A studio that builds companies from scratch.
4421Lab was founded by three people who have spent their careers building and selling technology, and who got tired of watching good ideas die for lack of a process.
Why a studio
Independent teams spend months, sometimes years, validating ideas, and most run out of money or focus before they reach a working product. Investors, meanwhile, struggle to find early teams that can actually execute.
Serbia has the engineering talent to build world-class products, but no system for turning ideas into global companies. 4421Lab is that system: one process, one team, many ventures.
