Frontend Web Development for Wealth Management Platform
the project
“Brainhub was very engaged and provided the best service possible.”
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
I’m the head of delivery for DACH and Italy for a wealth management platform solution. We’re a utility provider and provide services to banks, insurances and asset managers.
What challenge were you trying to address with Brainhub?
We hired them to do frontend development for projects in Germany and Italy.
What was the scope of their involvement?
Brainhub did frontend development on a website using React, Redux, and TypeScript. We had created the wireframes with the design team and had our own developers. About 8 developers from Brainhub joined our individual Scrum teams. They participated in planning meetings, daily calls, retrospectives, and development.
Additionally, they supported us in implementing a test automation framework called Cypress, helping us set it up. After the initial setup, the project team took over the framework.
What is the team composition?
We worked with an account manager and about eight frontend developers from Brainhub.
How did you come to work with Brainhub?
I found them on Google while looking for a company who provides staff augmentation for top notch React developers. When searching on Google, Brainhub showed up in the top 10 results and through the entire vendor selection process. they presented themselves very professional. Although we issued an RFP to look at alternatives, Brainhub was the clear winner.
How much have you invested with them?
We spent roughly £500,000 (approximately $613,000 USD).
What is the status of this engagement?
The project lasted from May 2021–April 2022.
What evidence can you share that demonstrates the impact of the engagement?
Brainhub was very engaged and provided the best service possible.
How did Brainhub perform from a project management standpoint?
We had weekly check-ins through Google Meet, and they addressed any performance issues we found. They also shared very good feedback when they felt we were missing something or that something could be improved. I could raise issues with them when needed, too. Overall, the experience was very positive.
What did you find most impressive about them?
Brainhub was very proactive and acted as a cohesive company instead of a group of individual contractors. They worked together and really took care of their people. Additionally, we appreciated that they had a key person managing the project who wanted to ensure they were providing the best results possible.
Are there any areas they could improve?
No, they were excellent.
Do you have any advice for potential customers?
My advice is to be really clear in regards to what you want. Brainhub will tell you if you’re not explaining what you need with enough clarity because they want to be successful.

Increased Throughput for Software Dev Team
"I wish I could work with developers like them all the time."
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
We are a digital marketing agency. Our specialization is performance marketing, which means we are always focused on numbers. I’m a project manager in the design and development team, so I am responsible, for example, for website development.
What challenge were you trying to address with Brainhub?
We needed a skillful and responsible software house for development projects.
How did you come to work with Brainhub?
We already had a partnership when I came to my organization.
How much have you invested with Brainhub?
We have spent roughly $25,000.
What is the status of this engagement?
We started working with them in early-mid 2015.
Could you share any evidence that would demonstrate the productivity, quality of work, or the impact of the engagement?
I can say that we were always focused on top quality and deadlines, which sometimes were really difficult to achieve, but we always were able to find a solution in every situation.
How did Brainhub perform from a project management standpoint?
Perfect. They have been using JIRA, which is very cool tool, and Slack for communication, which is also a pretty good choice. After working a few days with these guys, you are sure that they know how to do stuff and that they are pros.
What did you find most impressive about Brainhub?
I found their mindset most impressive because they are not just a group of developers, but they are a group of cool people with extraordinary developer skills.
Are there any areas Brainhub could improve?
To be honest, I don’t have anything in my mind at the moment.

ReactJS Developers for Software Startup
"[Brainhub have been] working without being pampered, without needing a lot of assistance, and only asking the right questions."
the reviewer
the review
A Clutch analyst personally interviewed this client over the phone. Below is an edited transcript.
Introduce your business and what you do there.
We're a small software startup, and we create sales management software for the automobile industry in Scandinavia. I am currently the chief executive officer/chief technology officer.
What challenge were you trying to address with Brainhub?
We needed qualified ReactJS developers. We had a hard time finding that in the market, so we went to Poland and to Brainhub.
What was the scope of their involvement?
The staff found Brainhub to be incredible. The sales effort was really effective. The resources we worked with in Brainhub were above our expectations. They were really good guys. They were working remotely. I went there for a visit for a couple of days just to meet and greet and agree on the contract details. They did all the work remotely using Slack to communciate with my developers, and that worked really well.
How did you come to work with Brainhub?
Their sales manager contacted us. I think he used LinkedIn. He did a pretty cool canvassing job [direct outreach] on us actually. The initial contact was with a colleague of mine and he said that these guys might be good. Then that was it. We started talking, and it turned out we couldn't identify a single project because we have changing priorities, and we needed a little bit of stuff done here and there. We ended up body shopping one developer from them for three months. The purpose of that was to identify and to clarify if they could be used for scaling out capacity. We did the three months, and they were perfect for scaling. We have them on the list now if we need to scale on React and JavaScript.
How much have you invested with Brainhub?
It was 300 Danish krone per hour, and it was full time at 40 hours a week. [~ $22,000 total].
What is the status of this engagement?
May 2016 through July 2016.
How did Brainhub perform from a project management standpoint?
We're using JIRA as a project management tool, and then we used Slack for direct communication between developers. We had a couple of project managers, but they were at that point not involved using Slack. They were more involved using JIRA. Other than that, there was a lot of direct communication between developers. The main thing was that they didn't need a lot of support. I've worked with other externals that basically said they knew everything about that form and the technology, and when it came down to it, they needed a lot of help. These guys didn't need any help at all. They were just up and running in hours, even though our platform can be pretty complex. They just got it up and running locally. When they were delayed on getting access to some data, they created some mock-ups really fast so they could continue working.
What did you find most impressive about Brainhub?
Working without being pampered, without needing a lot of assistance, and only asking the right questions. Also, not being afraid to ask when they had a real question. Some people don't ask when they need to, and these guys ask when they had real questions. They didn't ask for stuff that a normal good developer should know.
Are there any areas Brainhub could improve?
No, not really. They did a good job, and they performed better than expected. I will be using them again if I need to scale capacity on that side of the platform.
