CrustLab provided backend mobile development for a sports betting app. Using Node.js, React Native, and AWS tools, they enhanced an existing platform on both iOS and Android to include live data processing.
CrustLab’s detail-oriented approach and development ability impressed the client, especially when they integrated live data feeds into the platform’s sportsbook. They made great suggestions for enhancements and workflow adjustments, and they communicated well via Slack and Google Meets.
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 CEO and sole owner of a company that created a social sports betting platform. Our service lets people bet with their friends without risking any money on the wagers.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with CrustLab?
We were looking for a development partner for the backend of our mobile application. Previously, we had been working with a different developer, so we needed someone who could come in and update the platform with new features and versions.
SOLUTION
What was the scope of their involvement?
CrustLab took over the development of our mobile app from a previous developer and continued to improve the platform. They primarily worked using Node.js, React Native, and a host of AWS services, and their teams developed for both Android and iOS.
One of the most important functionalities that they implemented was our live sportsbook. For this feature, they integrated our whole data flow in near-real time, which was a big challenge for us to overcome. They also did some design adjustments and testing for our platform.
What is the team composition?
I worked with 6–7 people from CrustLab’s team. To start, Adam (CEO) did our project estimation and kicked everything off, then he handed it over to Marcin (Co-Founder) who served as our project lead.
How did you come to work with CrustLab?
We did some research online for companies who matched our needs, and we ended up with three options. We asked two of these companies for offerings, going through two rounds of offerings with each one. In the end, we selected CrustLab because we thought that their impressive experience working with sports data justified a bit higher of an investment.
How much have you invested with them?
We invested around €30,000 (approximately $35,000 USD) with CrustLab in this project.
What is the status of this engagement?
We worked with CrustLab from December 2020 – June 2021.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
It’s difficult to share measurable results, since a lot of their work involved optimizing our backend — I can say that their development has been very helpful to us. The biggest success of the project was the integration of our live sportsbook, since rapid data processing can be so difficult.
How did CrustLab perform from a project management standpoint?
Their team handled project management as part of the engagement. For everyday communication, we relied on Slack and we also had weekly meetings via Google Meets.
What did you find most impressive about them?
The best part of working with CrustLabs was their attention to detail in every step of the development process. They were great about taking the initiative to suggest new enhancements and features that our product owners hadn’t thought of. Their team also had a lot of optimizations and best practices that they shared with us, which was helpful.
Are there any areas they could improve?
I would have liked to have received more regular, unrequested updates. However, we shared this feedback with them during the development, too, and they were able to adapt to better meet what we were looking for.
Do you have any advice for potential customers?
Have a clear idea of what you want, but stay open to their recommendations and expertise. CrustLabs has a lot of experience, and that can be really helpful for any development project.

CrustLab worked closely with the owner of a sports betting platform to provide UI/UX design and web development services. They collaborated closely from wireframing all the way through prototyping in Sigma.
CrustLab’s impressive domain expertise lets them collaborate with the client to execute their exact vision. They met frequently to discuss both granular updates and larger goals for the development. CrustLab communicated clearly and openly using Skype, Zoom, and Sigma.
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 founder of an online sports betting platform, though I have since left that platform behind to join another betting company.
OPPORTUNITY / CHALLENGE
What challenge were you trying to address with CrustLab?
Given that it was a new platform, I needed to build the entire project from the ground up. Sports betting is very complicated on the backend, so I was looking for a design team that had experience in that space and wouldn’t need to have all the lingo and inner workings explained to them.
It was also very important to me to find a company that could both execute on the UI/UX design and either lead the project themselves or contract with someone to manage the actual development.
SOLUTION
What was the scope of their involvement?
CrustLab helped me complete a full UX design project for this product. We started with a web version of the platform, and we had planned to add a mobile version eventually. CrustLab was there through the full process, from ideation to mockup, to a fully interactive prototype within Sigma.
I had a lot of ideas about how I wanted the product to look, based on my past experience in the domain, so I was able to give them wireframes to work with. I’d meet with the lead designer to go over the iterations on each screen, make suggestions about new screens, and draw up more wireframes. It was a very collaborative process, which is what I wanted.
What is the team composition?
Adam (CEO) was involved with a lot of aspects of my project, and I also had a designated designer with whom I worked closely on the development.
How did you come to work with CrustLab?
I actually found CrustLab by searching Clutch. I was looking for a team that had great reviews within the specific domain of online sports betting
How much have you invested with them?
During my time working with CrustLab, I invested $1,000–$5,000.
What is the status of this engagement?
I worked with CrustLab from May–August 2020.
RESULTS & FEEDBACK
What evidence can you share that demonstrates the impact of the engagement?
CrustLab delivered exactly what I wanted, which was fantastic. A lot of designers don’t want to be a part of the project moving forward, they just want to deliver something and move on to their next work — CrustLab was truly interested in collaborating with me. They seemed very invested in working together for a longer period of time.
It was definitely a process to get there, but the final design they delivered looked great. The goal of the project was to get the design completed and ready to raise investment funding, and they absolutely got it to that stage. We have an interactive, clickable prototype that totally works, and we could essentially present it as-is.
How did CrustLab perform from a project management standpoint?
I met with the lead designer 2–3 days per week to share updates, and I met with Adam once per week to talk about our overall concept. They didn’t miss a single meeting, which is a huge deal when working with external developers.
We mostly collaborated within Sigma, the design tool of the project. We communicated via Skype and Zoom, which was helpful for sending drawings back and forth. CrustLab was always on time and always prepared for our meetings.
What did you find most impressive about them?
What was most impressive to me was that they actually had their domain expertise. CrustLabs knew the nuances of building a platform like this — you can’t fake that in such a complicated industry.
When I’m ready to do my next project, they’re going to be my first phone call.
Are there any areas they could improve?
No, I don’t think there are any areas for improvement.
Do you have any advice for potential customers?
CrustLabs probably isn’t right for a company that just wants someone to execute a set plan and throw the project back over the fence. What makes them so good is that they get deeply involved in the process itself and act as another set of eyes. With their domain expertise, they can give suggestions, point out issues, and iterate on a wireframe. They’re not just an execution workshop.

CrustLab developed a content management system for a technological institution and integrated it into their web portal. They were tasked with designing the system, developing its front and backend, and more.
CrustLab successfully delivered a product that was able to maintain its performance despite some sudden surges in the site's traffic. Their proactiveness and extensive technical expertise allowed them to provide valuable insights and optimal solutions to ensure the project's timely delivery.

BACKGROUND
Please describe your company and your position there.
The PFR Foundation conducts social activities through the implementation of projects in the field of education and science, including equalizing educational opportunities, equalizing opportunities on the labor market for various social groups through educational programs based on new technologies, counteracting digital exclusion, and strengthening the competences of the future of children and adults.
In 2019, the Foundation of the Polish Development Fund initiated the project: Central House of Technology - CDT, located in the center of Warsaw, with a modernly equipped space offering interdisciplinary educational activities in the STEAM methodology for children, adolescents, adults and the elderly. As the Managong Director of CDT I am responsible for overall activity of the institution.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire CrustLab, and what were your goals?
The main challenge of this project was the Content Management System development along with adding it to the current version of the web portal based on the java Magnolia framework.
The global situation related to the Covid-19 pandemic turned out to be an additional challenge. The real need to introduce distance learning forced the Central House of Technology to accelerate the project implementation.
The knowledge base aims to support education and to promote remote learning, therefore another challenge was fast publication of materials for teachers about remote lessons and additional complementary activities for students.
As with every content-related project, SEO optimization was a separate challenge. To make it easier for teachers and students to find the content of the knowledge base, we conducted on-site optimization.
SOLUTION
How did you select this vendor and what were the deciding factors?
We were looking for a subcontractor who would be able to work in the Magnolia framework, had good opinions and had a large enough organization to ensure efficient implementation of the project.
Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.
As part of this project they provided services such as design, front-end development, back-end development and Responsible Web Development. At the first stage of the project a web application was designed - it contained some knowledge and specific lectures for both students and teachers.
The content was divided into four categories: webinars for teachers, daily dose of technology, digital debutants, and a database of lessons for students. Bearing in mind the creation of positive user experiences when using the knowledge base, the important element to design was a search engine.
How many people from the vendor's team worked with you, and what were their positions?
Five specialists were working on the project, they were UX / UI designer, front-end developer, back-end developer, DevOps and Project Manager.
RESULTS & FEEDBACK
Can you share any measurable outcomes of the project or general feedback about the deliverables?
The most important result of the cooperation is the timely implementation of the project. In addition, the cooperation ran smoothly, and the developers' great commitment was visible.
The most important test for the system was the period of "maturity exams" (polish high school graduation exams) and increased interest in training materials posted on the portal. Despite the several times increased traffic, we did not notice any problems with the performance of the portal.
Describe their project management style, including communication tools and timeliness.
Project management was very well organized. We met during regular sprints. In addition, I could keep in touch with the Project Manager by phone or email. The implementation of the project was fully transparent thanks to the access to Jira, where I could follow the progress of work on an ongoing basis.
What did you find most impressive or unique about this company?
CrustLab is not only a specialist in the field of development. I really liked the fact that I could count on their advice at the product design stage. Thanks to their experience and ability to predict problems, we found solutions and built the project on time.
Are there any areas for improvement or something they could have done differently?
I have no objections, the cooperation was as it should have been.
