Mind Studios

(4 reviews)
Long-Term Technology Partner for Growth-Stage and Mid-Market Companies
Recommended
Founded in 2013, Mind Studios is a custom software development company working with growth-stage and mid-market businesses across the US, UK, Europe, and MENA. The portfolio spans logistics platforms, real estate marketplaces, healthcare systems, and fitness ecosystems - operationally critical products built for companies where technology is central to how the business runs. The team engages at the architecture stage, before the critical decisions get locked in. Business analysis, technical scoping, and honest pushback on briefs that won't hold up at scale are standard. The goal from day one is a system that doesn't need to be rebuilt in two years. What distinguishes Mind Studios is what happens after launch. Scaling infrastructure, iterating on features, extending systems as the business grows - this is where most of the value gets built, and where long-term client relationships form. The average engagement runs over two and a half years. Many go considerably longer. 100+ specialists. 13 years in business. 70% client retention rate.

We help companies in fintech, edtech, healthtech, retail, logistics and beyond shape, design and build web, mobile and AI products. Our product leaders, senior designers and AI-native software engineers work as one team. We get to know your business and shape the product with you, and then the same team designs, builds and grows it. Everyone on your project is a Tallium employee, and the same people stay with your product for years. You can start with a focused proof of concept to test the idea, show investors or win your first customers with limited risk. As the product gains traction, we grow it into a full product team, and the engineers who already know your code bring new people up to speed. With AI-first engineering, AI agents handle routine coding within the standards we set for your project, and a named senior engineer approves every merge. The same budget covers more of your roadmap. If you can’t share code with an AI model, we use our classic process instead. 120+ people since 2012. Headquartered in Amsterdam, with R&D centers in Kyiv and Rzeszów.
