Feedback summary: 

The app's improved design and usability have increased confidence in the product as a whole. Workflow between teams was very effective, both simplified by having only one point of contact and expedited by prioritizing availability.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I am the founder of a multi-service platform based on blockchain technology. The platform will try to bring people together and offer them an passive income for their human data as property.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Zipper Studios?

Zipper Studios is doing the redesign for our mobile client. They've created the UI/UX design in Sketch and implemented it in our Android app.

What were your goals for this project?

The problem on our app was the design and we decided to change it, this app is part of an blockchain platform that will connect users to our services. This new design make us more confident in our project.

SOLUTION

How did you select this vendor?

I came in contact with one of their business managers after someone from my network recommended them. They were professionals and their portfolio and previous clients definitely reflected that.

Describe the project in detail.

We have a native Android app that need redesign of UI/UX. Zipper Studios is doing the redesign and implemented it in our Android app, this app is part of an blockchain platform that will connect users to our services.

What was the team composition?

We worked with 1 project manager, 1 developer and 1 designer from Zipper Studios. 

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

Before working with Zipper Studios, I hired another remote team in the past but that experience was a complete disappointment. I needed an MVP delivered fast because I was looking to get a round of investment. Zipper Studios not only helped us cross the finish line but they understood our product’s needs, got involved and delivered the MVP very efficiently.

How effective was the workflow between your team and theirs?

The workflow between us was very effective. We had only one point of contact (Vlad, Co-Founder) who managed the whole team by creating and assigning tasks.

What did you find most impressive about this company?

The communication was excellent, they were always available and they truly understood the product. It really felt like they were part of the team.

Are there any areas for improvement?

I can’t see any ways they could improve. The communication and development process went so smooth, I couldn’t have hoped for anything better.

Feedback summary: 

Internal stakeholders are pleased with the platform’s stability, speed, and design, particularly its UI. Zipper Studios takes ownership of their work by understanding requirements and managing expectations. Customers can expect a committed, caring partner with strong technical expertise.

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 managing director of GoHustly. We’re developing a booking engine for hotels.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zipper Studios?

My company has outsourced all development of our hotel booking platform to Zipper Studios.

SOLUTION

What was the scope of their involvement?

Zipper Studios built the front- and backends of my platform from scratch using AngularJS and AMP HTML. We’re using Firebase, and there are some cloud functions.

Zipper Studios developed backend features that allow hotels to list all of their room types, restrictions, rates, and so on, along with an availability calendar. We connected that to the frontend, where users enter information—including check-in and check-out dates, the number of people in the room, room type, and personal and payment information—to book a room.

What is the team composition?

I primarily worked with Zipper Studio’s CTO and project manager. They also assigned one designer, two developers, and someone who helped with staff management and paperwork. We had an extra developer at one point, but we realized we didn’t need him.

How did you come to work with Zipper Studios?

I had the chance to meet them in person while I was in Sweden. Their CTO flew there to visit me, and we discussed everything over a few days. We were on the same page, so I decided to work with them.

How much have you invested with them?

I’ve spent around $30,000 on their services so far.

What is the status of this engagement?

We started working with Zipper Studios in June 2017, and the project is ongoing.

RESULTS & FEEDBACK

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

The system looks great; it has a very nice UI. It’s quite stable and fast, given that Google backs the technology we're using.

How did Zipper Studios perform from a project management standpoint?

They have understood everything from the beginning, and they provide the technical expertise I need. We had to change the project manager when he couldn’t cope with the requirements. However, before we could say anything, the CTO noticed and made the decision at the right time. We’re using Slack, Skype, email, and phone for communication, and Trello for project management.

What did you find most impressive about them?

Their involvement is their most impressive attribute. They care about the project, and they help with not only developing the product but also selling it. They’re more like a part of the company and less like an extension of my team. They simply care.

Are there any areas they could improve?

I don’t think so.

Do you have any advice for future clients of theirs?

Clients should remain involved, weekly if not daily, and not just send requirements and expect results. It’s important to remain involved throughout the development process, unless Zipper Studios has a very clear picture of what the product should look like.

The platform has a chat feature that employs text-to-speech and speech-to-text functionalities. The interface provides a feed containing the information requested by the user or the information the system wants to send to the user. The main tab is a kind of social media feed that contains different information relevant to the user. We also have an agent chat tab and a push notifications system.
 
What is the team composition?

We work with 2–4 developers from Zipper Studios, depending on how many hours a feature requires and when we need it delivered. We prioritize key features. Filip (Co-Founder, Zipper Studios) is our main contact and lead developer. I don’t need to communicate with the other team members.

How did Zipper Studios perform from a project management standpoint?

Zipper Studios is performing very well. We use some tools to improve communication and project management, including Jira and Slack. We’re using a scrum methodology.
 
What did you find most impressive about them?

We’ve worked with other developers in the past without any success. Zipper Studios has been our partner for a core part of the platform.

Use scrum principles. Zipper Studios is an excellent company to choose for this type of work.

Feedback summary: 

Zipper Studios is extremely organized and uses various tools to manage the project and maintain constant contact. They take time to understand project goals to develop the best product possible.

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 RunLive Inc., a sports tech startup. Our first product is a running app that allows users to connect to each other in real time and run together, no matter where they are in the world.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Zipper Studios?

We had a firm build our iOS app, but we needed a new partner to improve the code and also build an Android version.

SOLUTION

What was the scope of their involvement?

Zipper Studios migrated the iOS code from Objective-C to Swift, cleaning up the code and making it more stable. They fixed quite a few bugs and also added some new features and improved the UX. They built the Android version from scratch, implementing the same types of features found in the iOS version. The iOS app is currently available in the App Store, and the Android app is about 70% finished.

Users enter how far they want to run, and the app connects them with someone in real time to run with. The app has a built-in rewards store and live leaderboard, and users can even schedule runs instead of doing it at the moment. They can also invite people to join the app through a built-in feature.

What is the team composition?

They provide one main point of contact, three Android developers, and two iOS developers.

How did you come to work with Zipper Studios?

They were a referral. I met them and was confident they could do the work, so I hired them.

How much have you invested with them?

We’ve spent about $80,000.

What is the status of this engagement?

We partnered in November 2018, and the work is ongoing.

RESULTS & FEEDBACK

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

Before hiring Zipper Studios, the iOS app was about 70% stable, but now it’s about 95%. They addressed concerns the previous developer wouldn’t, making the app more stable, sustainable, and scalable. Now that we’ve fixed some bugs and added features, users are spending more time in the app.

How did Zipper Studios perform from a project management standpoint?

They manage the team well and are highly organized, which makes my job much easier. We use Trello to manage tasks, Slack to communicate, and Fabric to track bugs.  They’re incredibly flexible, adjusting to my schedule and time zone.

What did you find most impressive about them?

They’re the most professional offshore partner I’ve ever worked with, and they have phenomenal communication. They follow up regularly and ensure the project is progressing smoothly, quickly addressing any concerns. Unlike other agencies, they take the time to understand our project goals and vision. They’re not just technically competent, but they also know how to make the best version of your product.

Are there any areas they could improve?

I can’t see any ways they could improve.

Do you have any advice for future clients of theirs?

Maintain open communication and give them as much information as possible. The more they know about your product, the better the partnership will be.
