Brainstack is a Ukrainian multi-product IT company that builds and operates consumer applications across three core niches: Parental Control, Wellness, and Artificial Intelligence. The company claims its portfolio reaches millions of users worldwide on iOS and Android. Its technical stack spans PHP, Python, Node.js, React Native, and Kotlin, supporting both cross-platform and native mobile development.
The team comprises more than 350 developers, designers, and marketers working across product disciplines. Alongside its live products, Brainstack runs an in-house R&D centre dedicated to testing new ideas and exploring adjacent opportunities. The company measures performance across three dimensions: revenue, user value, and lessons learned - and adjusts its product approach based on data.
Internally, Brainstack describes its culture as one that gives people genuine ownership of their work and room to grow without what it calls "artificial ceilings," while holding a corresponding expectation of tangible outcomes. The company also runs Focus on Impact, a social initiative supporting military families and community projects in Ukraine.
