Mind Studios
5
(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.
