About
Amjad Masad co-founded Replit in 2016 and turned the browser REPL he open-sourced from Amman years earlier into the AI coding platform valued at $9 billion in its March 2026 Series D — with revenue that ran from $2.8M to $150M in under a year as 'vibe coding' took off. A Jordanian of Palestinian heritage who graduated from Princess Sumaya University, he was Codecademy's founding engineer (his jsrepl powered its in-browser tutorials), then ran Facebook's JavaScript infrastructure team through the React Native era. He co-founded Replit with his wife, designer Haya Odeh, and his brother Faris.
