Feedback summary: 

In testing, the MVP’s functionality met all expectations. The team’s determined approach to the project resulted in a quick turnaround time for each iteration. Their industry expertise and high collaborative skills laid the foundation for a productive engagement.

BACKGROUND

Please describe your company and your position there.

I had an idea for a mobile app game called Solopreneur.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mentalstack?

With no prior experience in gaming or development, I needed to outsource the work.

What were your goals for this project?

I wanted to build a minimum viable product (MVP) and test it with a small group of users.

SOLUTION

How did you select this vendor?

I conducted an online search and shortlisted several candidates. Each shared a pitch based on my development brief. Mentalstack showed a result-oriented attitude and exceptional agility in their proposed approach to the project. I also reviewed their reputation on Upwork, which was largely positive.

Describe the project in detail.

Mentalstack began building an iOS application. After four development rounds, we had a working MVP, but I chose to pause the project for personal reasons. I relocated and needed to focus on generating income in a new country. My decision had nothing to do with Mentalstack, they performed well throughout our engagement.

What was the team composition?

I spoke with the lead software developer daily, but I was also in contact with a customer support representative.

RESULTS & FEEDBACK

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

We tested the MVP on our same Wi-Fi network and the application met the key functional requirements.

How effective was the workflow between your team and theirs?

The collaboration was smooth and effective. Their team was technically knowledgeable and proficient.

What did you find most impressive about this company?

With a customer-first attitude, their team worked quickly and productively.

Are there any areas for improvement?

There are no areas come to mind.

The Review
Feedback summary: 

The apps’ stunning, user-friendly designs can be credited to the immeasurable talent of Mentalstack’s development team. While their regard for post-release bugs is lacking, they make up for it with their attentiveness to core development and client satisfaction.

BACKGROUND

Introduce your business and what you do there.

I’m the president and founder of a development agency. We partner with agencies to develop products and services, in addition to engaging with our clients on internal projects.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mentalstack?

We needed help completing trial projects for two of our clients.

SOLUTION

What was the scope of their involvement?

We initially brought Mentalstack onboard to assist with just foundational work, but as time progressed, they were involved in every facet of app development. One of the products that they helped us develop was a blockchain app that allows users to invest in cryptocurrency with ease. We gave them a mockup of the design, and they built to our specifications. They also helped us with an early web release and included more features that weren’t in our original vision

The second app was a winery platform that connected wine lovers to beverages with an algorithm that analyzes their disclosed taste palate. We didn’t provide raw mockups for this app, so they had to redesign the app concepts from our PNG files. They also helped us with an early web release for the blockchain app. They also included more features that weren’t in our original vision.

Both apps are fullstack, so they’re available on all platforms including web, iOS, and Android.

What is the team composition?

We mostly interact with their project manager. Having multiple points of contact can be overwhelming, so we appreciate them for having one designated liaison.

How did you come to work with Mentalstack?

I discovered them while searching for app developers on Upwork. The project we initially hired them for was scrapped due to our client's funding. When future projects came along, we reached out to them via Skype and offered them the job.

How much have you invested with them?

We spent a little more than $65,000 to develop both apps.

What is the status of this engagement?

They’ve been working on the apps since April 2018.

RESULTS & FEEDBACK

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

Mentalstack is very results-driven, so we do not doubt that their work will live up to our expectations. Everything that they’ve produced for us so far has been incredible, but a few small bugs have popped up. We understand that they don’t want to take attention away from core development, but it makes us look bad to our clients when they’re taking weeks to resolve simple issues. To prevent this, we hired an in-house developer to work with them on post-release bugs.  

How did Mentalstack perform from a project management standpoint?

Our teams have biweekly meetings to discuss which features are on the agenda for development. We used Jira to cross-reference the sessions with work tickets, and they used the platform to provide frequent updates on their progress.

What did you find most impressive about them?

The project manager was extraordinary at his job. They’re working with a dozen other companies, yet they make us feel like our needs are their top priority.

Are there any areas they could improve?

They tend to neglect smaller tasks, which could easily be avoided by bringing a designated engineer on board to resolve technical issues while the rest of their team works on new developments. We also don’t like how pushy their sales team are, but we understand that’s common for most companies.

The Review
Feedback summary: 

Working from no documentation, the team was able to understand the project quickly and build out effective apps that function well and are bug-free. They displayed excellent attention to detail, managed the project effectively, and communicated well.

BACKGROUND

Introduce your business and what you do there.

I'm the manager of a technology consulting company. One of the things we do is outsource development work for apps for our clients.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mentalstack?

Our client had an app that had been in development for a year. It was unfinished and had a lot of features that were missing. We took over the project and needed someone to take on the development.

SOLUTION

What was the scope of their involvement?

The application is for both Android and iOS, and we hired Mentalstack to develop both, as well as to build out the API. The applications are native, for a client with a general membership of several thousand people that they want to keep in touch with. They also want to post news and get information from the members, conduct polls, and include some event functionality.

We didn’t have much from the original developers to provide to them. We had to schedule several meetings with the Mentalstack managers in order to explain the project. We had designs and wireframes which we gave to them.

How did you come to work with Mentalstack?

We found them on Upwork. We posted the project, and they were one of the biggest companies that replied to us. We felt safe giving the project to a larger software house.

How much have you invested in them?

We have invested around $50,000.

What is the status of this engagement?

We started working with them in September 2017 and the work is still ongoing. The project is in its later stages.

RESULTS & FEEDBACK

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

The project itself had a lot of features and a functional API already developed. They had to take all of that without any documentation. We were unable to provide them with any information about what the API did and where the bugs were coming from. They had to understand what they were doing and did it without our help.

They pay great attention to detail. Compared to the version they got when they started the development, the app is so much more usable and is now spotless.

How did Mentalstack perform from a project management standpoint?

We communicate with them through their managers, but we have access to the help desk and we can see what they're doing. They have a lot of people on staff, besides the programmers, who take care of testing, reporting, and other things.

We pay them through Upwork, and through the Upwork platform there is time tracking for each developer, so we can pay them based on the hours they work. Additionally, they use HubSpot internally, and I use their HubSpot reports to complete my own reports based on the tasks completed.

What did you find most impressive about them?

The most impressive thing is when we tell them about any new features or changes that the client requests from us, they are able to understand right away and do it without having to go back and forth.

Are there any areas they could improve?

It would be good to have a little bit more communication directly with the programmers because we mostly deal with the managers. I can communicate with the developers through Atlassian, the task management program that they use, but generally, if the developers have questions, they don’t ask; they ask their managers who then come to us.

Mentalstack developed a high quality mobile app that's been well received by users. They continue to provide optimal customer support and fix any bugs quickly, while remaining flexible to client needs. 

BACKGROUND

Introduce your business and what you do there.

I'm the CEO of a company that has developed an app that helps people find street parking.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mentalstack?

We needed to find an app developer to help us build our mobile platform for both iOS and Android.

SOLUTION

What was the scope of their involvement?

Mentalstack designed and developed an app for both iOS and Android from scratch, based on the specifications and requirements we provided. They also provided testing and worked with us closely throughout development, so we could make changes and adjust features as we progressed. They incorporated mapping components that communicate to our API and populate specific information on the map, so users can find available street parking.

What is the team composition?

We work directly with a developer and a project manager.

How did you come to work with Mentalstack?

We posted the project on a couple different online forums and jobs boards and interviewed a few vendors that reached out to us. Mentalstack seemed like the best fit because they offered competitive pricing and could develop the app for both iOS and Android.

How much have you invested with them?

We've invested $10,000–$15,000 thus far.

What is the status of this engagement?

We started working together in March 2018 and they're still working on additional features in the app for us.

RESULTS & FEEDBACK

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

Not only did Mentalstack finish development on time, but they also provided high-quality work that's been well received by our users. They've been good about fixing any bugs quickly as they pop up as well.

How did Mentalstack perform from a project management standpoint?

We typically have a meeting over the phone with them every morning and manage project tasks through Trello. They've been able to meet our tight deadlines, so we're very happy overall.

What did you find most impressive about them?

In addition to their technical expertise, Mentalstack is also very flexible and easy to work with.

Do you have any advice for potential customers?

I would only recommend asking them about their holiday schedules before setting up a timeline since they're located in Russia and often take longer holidays than in the US.

Mentalstack's high-quality web development support has helped the company raise capital and move forward with a series of commercial pilots. Proactive and thorough in their approach, their team is easy to work with. They're also competitively priced compared to others in the U.S. 

BACKGROUND

Introduce your business and what you do there.

I'm the chief technology officer for an insurance tech startup.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mentalstack?

I needed additional development resources to help build out a service as a software platform on Microsoft Azure.

SOLUTION

What was the scope of their involvement?

Mentalstack worked with us from the inception of the company, facilitating most of our technology roadmap and staff augmentation. They worked within Angular JS, OCR engines, and Microsoft Azure frameworks, developing both frontend and backend designs for the platform on the cloud.

What is the team composition?

I work with Kirill (CEO and Founder, Mentalstack), Igor (COO, Mentalstack), and about 7 resources, including a project manager, someone in QA, and developers.

How did you come to work with Mentalstack?

I found them online and felt they were the best fit after interviewing a couple other vendors. 

RESULTS & FEEDBACK

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

Mentalstack has guided us through several series of successful rollouts, from wireframe inception to raising capital to moving forward with commercial pilots. We're very happy internally with their work overall.

How did Mentalstack perform from a project management standpoint?

We run a tight ship and work alongside their project manager through bi-weekly sprints. They've been very thorough in each sprint and are accessible through Slack.

What did you find most impressive about them?

They're hardworking, knowledgeable, and diligent. Compared to many domestic developers, they also offer a great value for the investment.

Are there any areas they could improve?

No, not really. Sometimes I worry about mitigating risk since we only work with about six developers and some are more junior than others. However, that's just part of working in a startup environment. I don't have any complaints thus far. 

Do you have any advice for potential customers?

I would encourage anyone to hire Mentalstack. It helps to have someone more technically inclined on your team involved in the process, so you can both collaborate more effectively.

The updated app attracted exclusively five-star reviews on the App Store. Mentalstack’s consistent availability, problem-solving skills, and eagerness to deliver excellent results contributed to a productive partnership.

BACKGROUND

Please describe your company and your position there.

I'm the founder/owner of Note Quest, a unique app for iOS that bridges music and education by helping users build note-reading skills at the piano. The app utilizes an interactive flashcard format with sound detection technology packaged in a game experience.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire Mentalstack?

Mentalstack took my minimum viable product (MVP) and overhauled the existing code, eliminating bugs while completely redesigning it. They also added several features based on user feedback.

What were your goals for this project?

I wanted to give the app an updated, fresh design and UI/UX. The project also involved adding features that were planned but not yet implemented.

SOLUTION

How did you select this vendor?

While transitioning from the previous developer, I interviewed three different vendors on Upwork. I looked specifically for Swift proficiency, experience with audio-based tools, and a basic understanding of music notation. I spoke with candidates after I allowed them to review my app's code; this allowed me to gauge each developer’s level of competency in regards to my job. Mentalstack seemed eager and passionate about my project, so I selected them.

Describe the project in detail.

First, the developer eliminated the app’s ties to an AWS (Amazon web services) backend server, which was causing unnecessary problems. Then, we started cleaning up the code, which wasn’t completely in Swift yet, while creating a more logical, cleaner format. Concurrently, the designer and I updated the visuals and made many UI/UX improvements. We also added several features that users had been requesting. In the end, we accomplished even more than I planned.

What was the team composition?

The team included a project manager, developer, and designer. The developer sometimes cooperated with other developers for QA assistance or input.

RESULTS & FEEDBACK

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

The app gained unanimous five-star reviews after its release. I can’t measure any long-term metrics since the release was only a week ago. My colleagues are enthusiastic about the app and are starting to promote it pro bono. The app is functioning far better than ever before, and the UX is much more attractive.

How effective was the workflow between your team and theirs?

Our interactions were smooth. The project manager spoke English fluently and communicated extremely well. Both of us were consistently available beyond our normal hours for questions or issues when they arose, which contributed significantly to our success.

What did you find most impressive about this company?

I liked their technical abilities and "can do" attitude when faced with challenges related to the niche nature of my project. They were eager to seek solutions that would work technically and satisfy my goals.

Are there any areas for improvement?

Because of their rapid growth as a company, there was a brief personnel transition. Once the transition took place, we had a smoother experience for the latter half of the project.

Feedback summary: 

The developers were extremely helpful in providing suggestions and helping to scope out the project and make it feasible and appropriate. The application is currently in demo and has been found to be very clean. They are reliable partners who work on a Kanban system, keeping to milestones regularly.

BACKGROUND

Introduce your business and what you do there.

I am the COO and CTO of a small startup which offers optimization, Google adverts, and software development.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mentalstack?

We don’t have our own in-house software developers and usually, we work with external partners for development.

We needed to build a web-based dynamic backend system where several applications could be added, such as a web-based operating system.

SOLUTION

What was the scope of their involvement? 

The platform was a new concept. We started with an introductory call where we discussed what the project entailed. After that, they brought in some developers to think about the project and give us their recommendations. This helped us a lot on the concept side, as well as the development side. The developers know what they are doing.

They used Node.js, TypeScript, AngularJS and Angular 2, and Elasticsearch for deep search interface. For the database, they used MongoDB, and we were connected to some other existing libraries from the Google Cloud, IBM Bluemix, and from Amazon developer’s platforms, as well as used some of their services.

We currently have a demo application for some closed groups to show what we are doing. It is existing, but not available for everyone.

What is the team dynamic?

I have one contact person who was responsible for the whole project and the communication. If there are specific questions which go deep into development, I can also contact the head of development. There’s one head of backend development, 2 senior developers, and one frontend developer. We also have one QA engineer.

How did you come to work with Mentalstack?

I’d been looking for developers for 4 months and had tested a lot of them. I originally found their profile as well as their developers through Udemy [online learning platform]. I don’t like to work through Udemy, so I looked them up myself and I found out they had previously done some great projects. We connected via Skype. I found they have clear communication and are deep into the technology — they know what they are doing.

How much have you invested in them?

I have invested between 70,000–85,000 [currency needed].

What is the status of this engagement?

We started in February of this year and the work is ongoing.

RESULTS & FEEDBACK

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

The user experience has been great. They created an icon for each function to make it clearer for the user to see where they need to click. They used colors to separate the different extensions of the system. The platform is very clean as it is based on the material design.

How did Mentalstack perform from a project management standpoint?

The project management is very good. Each project can be better — there is never 100% — but the project management from their side has been very good. We receive weekly reports from them outlining what had been done, some results, where they had allotted their time, and parts they struggled with. They also add a prediction of what would be done in the coming week, and when it will be completed.

We work on the Kanban system, set up with milestones. It is very clean and we know when work will be done. They deliver on time, and if there are ever delays in deliverables, it is from our side. Our direct communication is through Slack.

What did you find most impressive about them?

I like that they take the time to speak about any problems in order to really understand what the customer wants. For example, developers normally just try to understand what you want, and then want to go ahead and try to develop. Instead, they take the time to think, ask the right questions, and start developing when they are ready. 

Are there any areas they could improve?

It is nothing big, but I would recommend that they host their own Slack system and bring customers onto their platform so that everything is already installed and ready for the project management. We use Slack from our side, not because they couldn’t do it, but it wasn’t done at the time, so I created it myself.

BACKGROUND

Introduce your business and what you do there.

We are an incubator for different startup projects. I am the CTO.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with Mentalstack?

We have several start-ups going on at the same time, and although we have some in-house developers, they were busy on other projects, so we used Mentalstack to fill in the gap.

SOLUTION

What was the scope of their involvement?

We're building a website that is a perfume personalization tool for mass market. The idea behind it is you can get online and go through a journey of finding the scents that you might like and personalize. We recommend a scent based on user's selections, and we allow to personalize the packaging. Users get the perfume bottle with custom name engraved on it. There are no other people doing anything like that on the market. We partner with one big perfume house that's making the perfume for the customers, but we are doing everything on the technology side and making recommendations. It's a website, and it works on desktop and mobile, it's a Node.js application with Angular 2 on the front-end.

How did you come to work with Mentalstack?

Originally, we were looking for freelancers, but we came across a few agencies. We evaluated their prior work and spoke to them on Skype several times. It ticked all the right boxes from technical and managerial points of view. We decided to get an agency rather than individual freelancers because we feel it works better from the responsibility point of view, tracking and for assurance. Sometimes, freelancers just disappear or you have little visibility and control on what's going on. The price was right, so it was a great choice all round.

How much have you invested with Mentalstack?

The project cost around $200,000.

What is the status of this engagement?

It's in the final stages. It's not completed yet. It's completed to a certain degree, but we're doing some final changes. It's a live product now. We received feedback from customers, so we're making changes. It may carry along for some time.

RESULTS & FEEDBACK

Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?

The project is delivered, the site is live. We’re always tracking all project activities. We’ve also done some external QA to validate the quality.

How did Mentalstack perform from a project management standpoint?

The project management was excellent. One of the things we've enjoyed most was working with our project manager. He was quite involved, and he was there all the time when we needed him to be. He gave us timely project updates, and the estimates were quite precise, so we had great visibility. 

What did you find most impressive about Mentalstack?

Compared to freelancers, it's a different category. It's a full stack agency – people with a variety of knowledge sets and skills. The team also made a great effort to deliver the project on time and flexible with working long hours and weekends. 

Are there any areas Mentalstack could improve?

Would be good if Mentalstack had more engineers and broader expertise. So if we need to get more developers on the project or use a different technology stack, they could allocate us resources easily.

    It's good value for the money for us. If they could have slightly more expertise, then it would be excellent. We get what we pay for.

    Sometimes, we had to go back and redo things they've done. That had to do with somebody not capturing the requirements accurately. It happened a few times, and it's not major, but they could be more accurate in some parts of the organization.
