In early 2025, Maor Shlomo, working alone and without outside funding, built Base44, a tool that turns a plain-language description into working software. Six months after launch it had roughly 250,000 users and was profitable, with a team that had only just grown to six. Wix bought it for $80 million, with further payments tied to milestones through 2029. One founder, half a year, tens of millions of dollars. That is the new development, and it is why a method for choosing what to build now matters more than ever.
