Infrastructure Market: Traxit Investment Launch & Callstack's €20M Acquisition of Margelo
Following Tractive's €770 million acquisition by Bending Spoons, 19 former members of the Tractive leadership team have launched Traxit GmbH, a low seven-figure angel investment vehicle targeting early-stage consumer, subscription, and pet-tech startups. Simultaneously, Polish React Native specialist Callstack has announced the acquisition of Vienna-based mobile engineering firm Margelo at a valuation exceeding €20 million. Backed by Viking Global Investors, Callstack aims to integrate Margelo's popular open-source libraries—including Nitro Modules, VisionCamera, and react-native-mmkv—to better serve enterprise clients. This consolidation highlights the growing demand for highly optimized, reliable mobile architecture and technical foundations as autonomous AI tools reshape traditional software development workflows.
Highlights a major exit-and-reinvestment cycle in the European ecosystem (Traxit) alongside a strategic software development consolidation (Callstack acquiring Margelo) motivated by structural shifts in how AI is altering software engineering.
