Our approach
We combine a unique tech-savvy culture, product-oriented approach, and strong focus on achieving business goals.
Domain proficiency
Deep domain proficiency requires a thorough understanding of the business context to provide the most effective solution. This translates to taking an analytical approach to recognizing patterns and user behavior – getting to know users and learning why certain features are needed or which platforms should be supported.
We are the team
Working together to build a product means a deep understanding of all the facets of the business and taking ownership of the product. Together, we can achieve more than the sum of our efforts – that’s why each of us works hard to add our best to the product.
Data-driven decisions
We do what will work for your product. We have intelligence systems specializing in validating hypotheses and helping you understand what will work best for your product. Such data-driven decisions add value to every application layer.
Reviews
Engage them as early as possible and lean on their technical, strategic, and architectural expertise. One of the best things about them is their technical and thought leadership.
Clutch Review
We needed developers to redesign the already existent features of our native iOS and Android apps. Communication was ideal, and they were always available for us whenever we needed to meet specific deadlines. They were always involved, and it was pleasant working with them. Their professionalism and quality of the code were excellent as well.
Clutch Review
Techstack has launched a customer web portal with great success. It has offered a great UX while operating with a large data volume. Thanks to Techstack's efficiency, the company has rapidly scaled the project team and provided an advisor resource.

FAQ
What work models do we support?
We strive to build a long-term relationship with our partners, so providing short-term development services isn’t our primary focus. We can provide product development from scratch, MVP development, staff augmentation, and a dedicated team.
Is product scope estimation free?
Yes, you can get a free estimation, consulting, and quality audit by requesting a quote from our experts.
Where are we located?
We have legal entities in Ukraine, Poland, Estonia, and Hong Kong. Our software development hubs are in Wroclaw (Poland), Kharkiv, Lviv, and Kyiv (Ukraine).
How long does it take to build a software product with Techstack?
Each development case is individual. Request a free quote on your product development so our experts can take a deep dive into your situation and come up with realistic timeline estimates.
Are all of our engineers in Ukraine, or do we hire worldwide?
Ukrainians make up the most significant percentage of our team members. They are now scattered around safe places in Ukraine, Poland, Germany, Spain, and other countries. We hire both Ukrainians based in Ukraine and elsewhere, as well as local technology experts in our newly opened location in Wroclaw, Poland.
Can we provide individual engineers for staff augmentation?
You can start with one engineer and gradually scale to a fully dedicated team of engineers when the situation requires it. However, we strive to build long-term relationships with our partners, so providing one-time recruitment services isn’t our primary focus.
How long does it take to hire a product starter engineer?
Hiring time depends on product specifics, market conditions, and position seniority. Usually, we hire and onboard product starters during the first month of our collaboration with partners.
Have we worked with startups before?
Yes, we have experience working with startups. We have worked on products in the scale-up phase providing our expertise and team extension, and we took part in the development of a startup from scratch, delivering UX and user research to come up with product ideas, implementing MVPs, scaling the development teams—everything—to product release and beyond. We’ve also built and launched a proprietary product for the hospitality industry, ServeMe, so we’ve walked a mile in your shoes. Find more details in our case studies.
Do we work with fixed-cost projects?
We don’t work with fixed-cost projects, but we work with time and material, and also we can provide QA as a Service and Consulting services, which are provided on a project basis.
