Replit
The browser-based coding platform, founded in 2016 by Amjad Masad, Haya Odeh and Faris Masad, that spent eight years as a free learning tool for students and hobbyists with ~$2.8m of annual revenue, then cut ~20% of staff (May 2024), turned away from professional developers, and launched Replit Agent (September 2024) — an AI that builds, runs and deploys whole applications from a plain-English description. On Agent, Replit became one of the fastest-growing software companies on record by its own figures: ~$100m of annual recurring revenue (ARR) by June 2025, ~$150m by September 2025, and "tracking toward" a ~$1bn run rate by May 2026 (company claims, unaudited). It raised ~$250m at ~$3bn (September 2025) and ~$400m at ~$9bn (March 2026) (reported). Its story also includes two defining failures of the "vibe coding" era: an agent that deleted a user's production database during a code freeze (July 2025), and usage pricing that surprised users with large bills (2025). With Cursor sold to SpaceX and Windsurf split between Google and Cognition, Replit by late 2026 was the largest AI app builder still independent, and its CEO said he would "rather not sell".
