Feedback summary: 

Because of the team’s consistent and reliable honesty, the client is able to trust in their growing relationship with them. They handle all their work with a personal touch, which encourages a continued long-term partnership. Communicating in several different ways, they easily stayed in touch.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

We’re a technology startup that builds marketplace mobile apps for the real estate industry.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco?

We needed help in creating mobile technology to facilitate our business goals.

SOLUTION

What was the scope of their involvement?

I’m not familiar with the technical end of things, so they came in and really managed the entire development process. We provided wireframes and overall ideas and business goals. Then, we worked with them to plan the product. They got to work and later helped us implement the technology.

The final product is a mobile platform that sells home services specifically for real estate professionals. Homeowners are also able to use the product. As of now, we’ve paused our Android development to realign from a business development standpoint. Their team also completed the web development end of the project, so we’re currently working on iOS. 

What is the team composition?

Originally, we were working with an iOS team, Android team, and a web development team. Now, we have a few iOS engineers, testing personnel, a business analyst, one project manager, and an API developer.

How did you come to work with Zco?

We found them on Clutch. Our team vetted them and several other potential vendors through interviews. We appreciate how much the Clutch platform provided for us, and the team used its listings as a guide to help narrow down our list. In the end, we had the best discussions with Zco and felt most confident in hiring their team.

What is the status of this engagement?

We started the project in March 2017, and the work is ongoing.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We’re extremely satisfied and grateful to have an excellent working relationship with them. With outsourcing, there’s always uncertainty surrounding how the relationship will work out. Two organizations aren’t likely to have the same processes or schedules, so it can be difficult. We’re happy to have our long-term partnership with them. 

How did Zco perform from a project management standpoint?

Our project manager was personable and helped to develop our ongoing relationship on a personal level. Whenever I need assistance, he’s on it. When there’s something urgent that needs deeper discussion, we jump on a video call to share screens and walk through issues. Otherwise, we use Basecamp, email, and phone to communicate. That’s been effective, so we don’t see a need for additional tools.

What did you find most impressive about them?

They’re trustworthy and dependable. Knowing that we have a company we can count on means a lot to us.

Are there any areas they could improve?

They’ve been great. I can’t say anything negative about them. 

Do you have any advice for potential customers?

I wouldn’t hesitate to hire them because of their trustworthiness. From a technical standpoint, they’re also very strong. I haven’t come across a situation where they couldn’t deliver on a feature we wanted. They’re professional and competent. It’s just a matter of managing the project the way you want to and finding the company you can rely on. If those things are important to you, Zco is the match for you.

Feedback summary: 

All initial feedback has been promising. The team at Zco delivers quality work. They’ll tackle any challenges and take scope changes in stride. Along with their responsiveness, their team is communicative and dedicated.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m on the marketing and business development side of a material handling company. We sell any service that goes into warehouses.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco?

One of our issues was that whenever we had sales reps inside of a warehouse, they didn’t have internet service. Because of this, the reps couldn’t pull up different product information on their tablets to show customers. In partnering with Zco, we hoped to eliminate that by creating an application that holds all of the literature, videos, and information about our products, which would be accessible without an internet connection.

SOLUTION

What was the scope of their involvement?

The team at Zco created an iOS and Android application for our sales team. When we met the first time, their team got to know our ideas before coming back with their suggestions. Once we decided on a solution, I provided all of the content before their team focused on all of the design and development.

We have around 200 products. The app would host all of the spec sheets, brochures, literature and any videos that went along with each product. It also has an ROI calculator. When the sales rep is meeting with the customer, they can punch in the parameters of the warehouse and receive what the ROI would be.

What is the team composition?

In total, our team has four people. My main contacts are Michael (Senior Project Manager, Zco) and Randy (Senior Account Executive, Zco).

How did you come to work with Zco?

We did a Google search. Our team was actually going to work with another company, but then we decided Zco would be a better fit. After interviewing several different companies, we went with Zco because of their responsiveness. They also wanted to come out and see our business. Their team wanted to learn what we do so that they would have the background before creating our product.

How much have you invested with them?

We’ve invested about $60,000.

What is the status of this engagement?

We started working with Zco in June 2019. We’re in the final stages, and it should be finished in the next few weeks.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We’re still in the testing phase. Our teams meet to go over issues or things that could be improved upon. Since we’re not experts by any means, they also give us feedback on what could be better.  

Everyone is excited about the app. Back in July, I revealed the concept during a sales meeting. I let everyone know what we were working on and what designs we had. All of our sales reps are pleased with it.

I also showed it to our vendor partners, who asked me about the development and who we hired. A lot of them want to do something similar with their teams. This morning, someone emailed me, asking for a couple of screenshots that he could share with his team.

How did Zco perform from a project management standpoint?

Their team is excellent at getting back to me. I could send them a message right now, and within seconds, they’ll respond. For project management tools, we use Slack, email communication, and sometimes Basecamp.

What did you find most impressive about them?

I have nothing but good things to say about Zco. I appreciate their responsiveness the most. If I’m having an issue during testing, they get right back to me. If I need to add something, they’re on it. Even if we throw a curveball.

Are there any areas they could improve?

No, they’ve done everything great. There are no complaints.

Do you have any advice for potential customers?

Let them know about your business and industry. Once they have that information, they can zone in on what’s important.

Feedback summary: 

Zco has released nine major iterations of the iPad app, each available in the App Store, as well as the initial version of the cross-platform Xamarin build. Their nimble team boasts a wide breadth of skills to match any given situation. Having clear documentation upfront has reduced onboarding time.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the director of R&D at Streamline Automation. We build inspection software for fire departments within a city municipality. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco?

We hired Zco to port our iPad-exclusive remote inspection software solution to a cross-platform build. The original was written using Objective-C, and the latest version would use .NET Xamarin to run on Windows and iOS.

SOLUTION

What was the scope of their involvement? 

Zco assigned two teams to work concurrently on our inspection software. The first team initially took over our native Objective-C platform to get a sense of our architecture and then continued to make enhancements throughout its lifespan. All in all, they’ve completed about nine major releases over the course of a year, building out new features as requested.

During this time, the second team was working on the Xamarin initiative to port the solution to Windows. They’ve completed the cross-platform version, and it’s now available in the Microsoft store.

What is the team composition? 

The first team consisted of an architect, a QA lead, and an Objective-C developer for the native iOS tool. That architect and QA lead would later go on to head the Xamarin team, joined by two Xamarin developers, a business analyst, and graphics artists to complete the package. The later helped with UI work, creating icons and other visuals.

How did you come to work with Zco?

We’d searched a number of companies but found that their fees were really expensive. Eventually, the owner of our company found Zco because they offered a reasonable price.

How much have you invested with them?

In total, we’ve spent about $250,000 so far. The Objective-C development cost a little over $102,000, and the Xamarin initiative has been about $150,000.

What is the status of this engagement?

We started working with them on July 2018 for the Objective-C app, and they’ve recently released the final version to the App Store. The Xamarin build started in September 2018, and we’re still working together to make enhancements.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

As I’ve said, we’ve had nine major releases to the App Store and one initial release to the Microsoft store. Each one has seen a great success rate. We’ve hardly ever had any QA issues after the fact, and, if we did, they were very responsive to them.

How did Zco perform from a project management standpoint?

We meet with their team once a week on a live conference call and interact using project management tools. Because we’ve been able to communicate our needs clearly, they’ve helped us hit all of our milestones by following our custom Scrum process.

What did you find most impressive about them?

Zco has a wide range of skill sets at their disposal, which allows them to adjust their team to as they see fit. For example, if we need a graphics artist or any other specialist, they’ll assign someone who can participate at the team level for a few short iterations. Once they complete the job, they switch out. 

Are there any areas they could improve?

No, we always have a high level of satisfaction with what they’re doing.

Do you have any advice for potential customers?

It’s best to have solid requirements and project definitions upfront before engaging any development firm. We were fortunate enough to have our software well-documented from our previous vendor, which became the basis for our requirements and project definitions. This helped minimize Zco’s discovery period.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I'm a founding partner of a fitness mobile app company called Challenge Me App.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco Corporation?

We engaged Zco Corporation to develop our mobile and web app.

SOLUTION

What was the scope of their involvement?

Zco Corporation designed and developed our app for iOS and Android from scratch, along with an administrative web-based platform to manage the app's insights, data, downloads, and other functions. They provided UX design in addition to development, using technologies such as PHP and MySQL. The app's features allow users to access and post to national leaderboards, accept fitness challenges from other users, and subscribe to fitness influencers. 

What is the team composition? 

We work with an account executive, the senior vice president, and a handful of designers, developers, and QA testers. We've probably worked with about 30 people on their team in total throughout different stages of the project. 

How did you come to work with Zco Corporation?

We found Zco Corporation at a networking event. We had also hired a business consultant to help us find the right app development company, and they were one of our top three choices. After meeting with them, it was clear that they were experts in gamification and other capabilities. We knew we would be able to scale easily if necessary with their team, so it would be possible to do everything we needed without having to hire any additional agencies.

How much have you invested with them?

We've invested over $300,000 thus far, or about $15,000 per month.

What is the status of this engagement?

We've been working with them since October 2017 and have continued the relationship through a monthly retainer. 

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Zco Corporation has been instrumental in the growth of our company. They've done a great job of managing our expectations when it comes to developing something that's never been done before. They've helped bring our ideas to life by laying out a data-driven approach to achieving those goals. 

How did Zco Corporation perform from a project management standpoint?

We use Jira and Basecamp to manage communications, addressing bugs and checking off tasks through each sprint phase in an efficient manner.

What did you find most impressive about them?

They have the ability to bring enough manpower to a project when needed in order to get everything done on time. We never have to worry about delaying our timelines with their ability to scale their team to resolve any issues that may come up. They're very business-development oriented, so they do what they need to do in order to hit our deadlines. 

Are there any areas they could improve?

No, they've made improvements wherever we've requested them to as they come up.

Do you have any advice for potential customers?

Have as many in-person meetings as possible with their team.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I am the program development manager for an automotive company. 

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco?

One of the items I’m tasked with is implementing a mobile app device for our B2B e-commerce website. We needed to find a tool that would allow our customers to utilize features that exist on a mobile device to improve their day to day tasks and responsibilities within their company. Simultaneously, we wanted to provide a simplified version of our current e-commerce solution. 

SOLUTION

What was the scope of their involvement?

Zco built our mobile apps from scratch. We used Xamarin to develop versions for both iOS and Android. Through the product, our B2B customers can access over a million parts to view and order via mobile.

The team led us through the starting point of a UX/UI design. Once those components were complete, they worked with our IT team on interfacing the app with our existing e-commerce solution through API calls. The apps are synced to our website live. When users place an order on the web platform, it shows up on the mobile app simultaneously and vice versa. 

In addition to this product, we've had discussions with Zco about a second app for our RV division. We're aiming to begin development for that product within the next few weeks. They're also helping us research a separate marketing application. 

What is the team composition? 

We deal primarily with a project manager. I believe their team of developers includes about six people in total. 

How did you come to work with Zco?

I actually started my search by vetting companies through Clutch reviews. Most of the other vendors responded via email. Zco was the first company to call me back immediately. I was impressed with their responsiveness. 

How much have you invested with them?

We've spent right around $70,000. 

What is the status of this engagement?

We've been working together since March 2018. 

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We just launched the app a few days ago. From an internal standpoint, we had a substantial number of immediate downloads. We have not officially started marketing or rolled this out to our customers yet. I expect that we'll begin to have external metrics in the next week or two. 

Qualitatively, our beta testing customers have responded with comments about the app's simplicity and ease of use. They find that it functions much better than the website in some cases. 

How did Zco perform from a project management standpoint?

We're very pleased in this regard. Zco meets any timeline we set. They have exceeded our expectations about managing and fulfilling our goals. Honestly, the biggest challenge has been getting them the information fast enough from our end. They implemented Basecamp for us to use to communicate any updates or changes to the requirements.

What did you find most impressive about them?

Responsiveness is Zco's number one strength. They are quick to get back to us and make any necessary adjustments or changes to the project. 

Are there any areas they could improve?

Probably the only area they could improve would be offering more suggestions in areas where we’re less well-versed. 

Do you have any advice for potential customers?

Zco would be a great partner for anybody who wants to develop a mobile app. From start to finish, Zco has been a fantastic company to work with.

The app generated two potential new ways to monetize results from data assets. An intuitive display format pragmatically organizes useful results from the raw input. The project manager consistently responded with remarkable speed. Developers rapidly completed tasks at a high level of proficiency.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I'm the owner and president of operations at Ward Aqua Farms, LLC. We’re a research-focused aquaculture operation that commercially produces shellfish. Our consulting operations strive to improve domestic aquaculture.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco?

Our business has the internal resources to measure specific water quality parameters. To better drive business decisions, we needed a software solution to convert raw data into actionable insight. The pre-set sensor configurations display results in a suboptimal format. I’d worked with discrete aspects of development but had never completed an end-to-end app build. Zco had the professional design and development qualifications we lacked internally.

SOLUTION

What was the scope of their involvement?

Our initial discussions clarified how to maximize our existing data assets and the ideal UX/UI. We collaboratively developed a basic starting template. The specs outline new types of metrics we wanted to gather. Zco incorporated my feedback on design specs including wireframes and storyboards. The iOS app lets me set custom alerts and apply my parameters to incoming metrics. User-configurable thresholds maximize data utility.

They transitioned hosting from a third-party platform to my Amazon cloud-based account. I have much more control over this platform. The app lets me conduct quality checks in-house. An intuitive display visualizes results from raw incoming data. Several design iterations and a data acquisition phase yielded a viable mobile app.

What is the team composition?

My two main contacts at Zco are the project manager and his supervisor. I've only interacted with those two resources but assume a full development team writes the code.

How did you come to work with Zco?

I considered several potential contractors. After finding Zco via Google, I contacted their CEO. Their excellent communication skills were the deciding factor. Most vendors can offer comparable development work. We had a tight deadline to get the quote into a federal agency. Zco was by far the most responsive option.

What is the status of this engagement?

We started working together in June 2017 and wrapped up the first phase by December. I plan to work with them again shortly to expand this project. Ideally, we’ll establish a new six-month scope in April 2018. Having established new uses, we’re going to develop the app much further.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Zco is an efficient and professional partner. I was amazed by the quality, speed, and accuracy of their work. We measured their progress against the scope and timeline. They offer a very fair price, especially in light of the project’s scope and quality.

The app generated two new pathways to monetization outside the original scope. Using this product in-house has reduced risk substantially and generated innovative future business opportunities.

How did Zco perform from a project management standpoint?

Zco walked me through the entire process. We used email 90% of the time with intermittent phone calls. I interacted with our project manager daily and only spoke with his supervisor about billing concerns. He always responded immediately, often within hours. The cost was split into five invoices, each one predicated on meeting monthly milestones.

Even though I frequently kept them waiting, they adhered to a challenging timeline. They probably could have finished in half the time if our supplier had promptly provided materials. Resources were straightforward, transparent, and seamlessly transitioned between tasks. They made critical changes to the original document on the same day.

What did you find most impressive about them?

I can't think of a single time our project manager took more than an hour to respond. He prioritized my needs regardless of off-hours, holidays, and even the time zone difference. I've never experienced that attentive level of support with any other vendor. This dynamic facilitated uniformly smooth and efficient progress.

Are there any areas they could improve?

I wouldn't change anything. Based on our great experience so far, I’ve extended their engagement.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I'm the VP of Administration at a manufacturing company. We manufacture swimming pool and spa filters.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco?

About five years ago, Zco built an iOS application for us and we wanted to update it to make sure it's compatible with the iPhone X. Since we also wanted to have an Android version, we decided to develop a hybrid mobile app that would work with both iOS and Android. We reached out to Zco and asked them to update the application they had developed previously.

SOLUTION

What was the scope of their involvement?

The hybrid application they built was essentially a duplicate of our existing app in terms of functionality, but they changed the look of the app and added new graphics. When we noticed there were some issues with our initial version, they addressed those issues. I also asked them to turn off some database searches that I wasn't maintaining correctly.

The app is for swimming pool and spa professionals, but it has some free functions and can also be used by homeowners. It helps users find cartridge filters based on the size and the model. Users can enter different parameters in the search fields and the app determines relevant cartridges, creating a catalog. Also, users can set reminders for cleaning their filters and watch instructional videos.

In addition to managing the app development, they’re helping us redesign our website and update its content.

What is the team composition?

I primarily work with our project manager and one developer.

How did you come to work with them?

Originally, one of my other vendors referred me to Zco.

How much have you invested with them?

We've spent over $100,000. (This doesn't include the website redesign, which will be over $40,000.)

What is the status of this engagement?

Our latest project began in December 2017 and we're still working with them.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

The app is widely used in my industry. When I do trade shows, people come up to me and compliment me on the app. Zco delivered everything on time and made sure the app is secure and bug-free.

How did they perform from a project management standpoint?

They're very upfront and responsive, explaining the process to me in a way I can understand. (I don't have an IT background, but they answer all of my questions.) We usually communicate via email, but initially, I talked to them on the phone to explain what exactly I needed. Sometimes, I send them emails at odd times and they respond almost immediately if it's within reasonable business hours. They also use Basecamp for project management.

What did you find most impressive about them?

I appreciate their response time and their willingness to work with my budget. They're very fair in their pricing.

Are there any areas they could improve?

No. I'm very satisfied with their work.

Do you have any advice for potential customers?

They're a great fit for anyone who needs to develop an app or a website, but doesn't have a background in IT. They're great communicators, so they’ll ask you many questions.

Feedback summary: 

Zco not only understood the vision for the app, but they helped shape it to be more robust and interactive. As a result of their forthcoming input and high-quality development, the app has received a tremendous amount of positive feedback from its market.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m a chef, author, and TV personality, as well as the founder and CEO of ALK Ventures.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco?

I hired them to help build my storybook/game app, Issa’s Edible Adventures, which surrounds a little girl named Issa who travels around the world to gather ingredients for her mom’s recipes.

SOLUTION

What was the scope of their involvement?

I came to Zco with the app idea, and we worked together to develop the imagery. Initially, it was going to simply be a storybook concept, but after working on character development, design style, and the 3D and 2D animation, the app evolved into more of a game concept. Zco helped me develop three game episodes that center around three of my recipes. From there, we underwent a lot of crafting and editing the dialogue. We then did voice-overs and developed music for the app. 

Zco has also been extremely helpful in launching and marketing the app. They submitted it to the App Store and created the promotional content for it. They’ve helped me with SEO as well, assisting in putting together keywords and phrases to boost the app’s ranking. They’ve also sent it to news outlets to help promote it.

Currently, the app is for iOS only, but we intend to create an Android version once I get more traction.

What is the team composition? 

Kevin Morrow, the senior account manager of Zco, was my initial point of contact. During development, I worked closely with Don Austin, Zco’s Executive Vice President, who liaised with about two or three of their developers on my behalf. I also worked with Matt Henry, their creative media director, who handled the sound and video production.

How did you come to work with Zco?

I had a very specific vision of an animated concept, so in my search, I prioritized developers who were skilled in animation. I was also interested in a work-for-hire basis to ensure I owned the future assets.

I came across Zco, and they had incredible reviews. I spoke to the references they provided, and they raved about them. I also appreciated that, unlike a lot of other firms I spoke to, they didn’t have to get external graphic designers to create images for me and then attempt to manipulate it into an app. They have a very holistic approach. Last but not least, I loved their work, so it wasn’t a difficult decision.

What is the status of this engagement?

We began working on the app in October 2016 and wrapped up development in early January 2018. The timeline was initially shorter, but as the scope of the project increased, so did the timeline. I didn’t have a strict deadline; I just wanted the product to be perfect. It took a bit longer than we thought, but I’m really happy with the end result. 

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

Because we just launched, I don’t have any data to offer currently. I can say that the reception to the app has been great. People are extremely impressed with the product. I’ve especially received positive feedback from charter and private schools, where I’ve been able to demo the app as a teaching and enriching tool. Some museums have shown interested in the product, and I’ll be doing a demo at the New York Hall of Science soon.

How did Zco perform from a project management standpoint?

Their communication is great. There was a lot of minutiae within the project, so we went back and forth a lot.I was able to reach someone on their team within a day. They work normal hours, so someone was always available to address my concerns within my eastern standard work hours. They’ve been great partners and I’m thankful I found them.

What did you find most impressive about them?

It’s been fantastic working with like-minded individuals who understand my vision and are dedicated to bringing it to life. They’re able to take your idea to the next level. I didn’t start with the same app I ended up with, and I’m really happy for that because I ultimately got a better product in the end.

Are there any areas they could improve?

I don’t have anything negative to say about them. They’ve done everything I’ve asked them to and were forthcoming throughout the process.

Do you have any advice for potential customers?

Don’t hesitate to work with Zco. They’re upfront about the cost, and they’ll deliver the best product.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m a product manager at an electrical connector manufacturer. We sell connectors and installation tools for utility and distribution in various markets.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco?

We wanted to build an app to highlight our wide range of products and clarify proper installation methods. We wanted customers with a particular connector, for instance, to be able to quickly identify which tool to use and understand how to use it.

SOLUTION

What was the scope of their involvement?

This was a multi-tier project. We initially provided an Excel wireframe that listed the basic functionalities we expected and the necessary data. We left the design work in their capable hands and they provided a custom user interface.

We then built a basic version of the app which we added onto in stages. The initial model focused on helping installers identify the connectors and tools necessary for any given job. Next, we added a feature to help inspectors validate electrical installations. We then built a function that allows users to easily find local sales representatives. Finally, we added our tool catalog.

They provided a beta version for us to test and made changes based on our feedback.

We’ve launched the iOS and Android models and plan to build a Microsoft version in the future.

What is the team composition?

We initially spoke with one of the sales representatives who set us up with a principal project manager. We stayed in constant contact with both of these individuals and they communicated our needs to their developers.

How did you come to work with Zco?

We found them on Google. We conducted an in-person meeting since they were nearby and we had a nice, comfortable discussion about our goals. They seemed very knowledgeable and offered a competitive price, so we made the decision to go with them.

How much have you invested with them?

Slightly more than $30,000.

What is the status of this engagement?

We started working together in November 2016 and completed the project in June 2017.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

The app has only recently launched, but the feedback we’ve received so far has been overwhelmingly positive. Users appreciate the functionalities and find the interface easy to use. We currently have roughly 100 registered users, though registration is not required.

It will take time for the app to catch on among our diverse network of distributors and end customers, but the tool works flawlessly and we haven’t received any complaints.

How did Zco perform from a project management standpoint?

Communication was very effective and responsive. We worked together through email and used GoToMeeting to conduct video conferences. We also conducted in-person meetings during the early stages of the project.

They utilized an effective system for improving on the app’s beta model, using a web portal to go over wireframes. We provided feedback, they made adjustments, and we repeated this process until we were satisfied with the product.

What did you find most impressive about them?

They have excellent customer service, responding to any questions within 24 hours. They also rely on highly skilled developers. We only found a single error in the beta test and the issue was resolved within 12 hours. Not only did they fix the problem, they also explained what went wrong in order to assure us the issue wouldn’t reoccur. Not many companies take that kind of care.

Are there any areas they could improve?

We worked well together and our project was a success, so I don’t have any suggestions.

Do you have any advice for potential customers?

It’s important to have a clear goal in mind when working with any developer. They may be unfamiliar with your industry, so it helps to precisely articulate your requirements and establish clear parameters. If you’re disorganized, your project may encounter issues.

We also set up a focus group on our end to ensure our product met all demands. We had our internal sales team and customers come in to review the app at various stages to gauge its usability. In this way, we took proactive steps to guarantee the success of our product on the market.

Zco offers highly competitive rates and transparent, responsive project management. They typically meet deadlines, though delays naturally occur given the niche nature of the project. Their dedication allows them to tackle the challenges of the burgeoning wearable technology field.

A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.

BACKGROUND

Introduce your business and what you do there.

I’m the Co-Founder of a company developing smart accessories capable of alerting friends, family, and police in the event of an emergency.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zco?

We hired Zco to develop the app for pairing our software with wearables.

SOLUTION

What was the scope of their involvement?

The app essentially presents users with onboarding tutorials that explain the setup process and how to use the product. It also prompts users to fill out personal information to assist police before pairing with a smart device. Zco provided design, as well as frontend and backend development, for the native iOS and Android versions of the app.

To begin, they designed screens based on a list of requirements we provided. We went back and forth on edits before development began. From here, they arranged the project in detailed milestones, producing deliverables for testing every couple of weeks.

In addition to developing the app, they provided website development at no extra charge. They also volunteered to assist with the production of marketing materials, creating a promotional video. As we approach completion, they’re helping launch our product on the App Store.

What is the team composition?

There are four or five people assigned to our project in total, though we communicate directly with two. We have a U.S.-based project manager who oversees the project, as well as a team lead who manages their overseas developers.

How did you come to work with Zco?

We were looking for developers in the Boston area and came across Zco, one of the world’s largest app development firms. They had a number of positive reviews, offered better rates than other agencies we considered, and had experience with projects similar to our own. We also seemed to connect with the team, so we decided they’d be a good fit.

What is the status of this engagement?

We started working together in August 2017 and our relationship is ongoing. We’re currently in the final testing phase of the project.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

While we haven’t yet launched the app, we’ve been very pleased with the work Zco has provided.

How did Zco perform from a project management standpoint?

We communicate through Basecamp on a daily basis. They’re very responsive and transparent about updates. They also stick to the budget, though our price did increase after we added to our initial scope.

While they stick to project deadlines, we did run into a software pairing issue that caused a month and a half of delays. Still, they worked diligently to identify the root cause of the issue and have done everything in their power to fix the bug.

What did you find most impressive about them?

They offer significantly better rates than their competitors. Additionally, while they rely on overseas developers, having a U.S.-based project manager ensures smooth communication.

Are there any areas they could improve?

There’s been a bit of a learning curve in working with wearable devices, but this is understandable since it’s a bit of a niche field.

Do you have any advice for potential customers?

Make sure your requirements are clear because they’ll provide exactly what you ask for. Be sure to be as detailed as possible.
