(11 reviews)
Fuelled by Excellence. Trusted by Leaders.
Tallium is a trusted partner for product co-creation, taking ideas from concept to award-winning apps through AI-native development and long-term collaboration. 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.
