From Jordan to a browser-based startup

Amjad Masad co-founded Replit, a browser-based coding and deployment platform that grew from an online programming environment into an AI app builder. He demonstrated Replit Agent on Lenny’s Podcast and discussed the company’s early years on 20VC.

Replit says annualized revenue increased from $2.8 million to $150 million in less than a year, as reported in September 2025. [2] ↗

Masad dates the company’s start to 2016. Moving the programming environment into the browser cut out local setup and made a working program easy to share. [3] ↗
Lenny’s episode notes identify Masad as an early engineer at Codecademy and later a lead on Facebook’s JavaScript infrastructure. The browser-based approach tied together education, collaboration and execution. [8] ↗
Lenny’s November 2024 episode reports 34 million global users and shows how Agent can create and modify a full-stack app from a text prompt. [8] ↗
Replit announced its Agent 3 launch in September 2025 alongside the round, reporting a community of more than 40 million users. [2] ↗
Replit confirmed that Agent deleted data from SaaStr co-founder Jason Lemkin’s app database. The company says he recovered it via rollback, and that Agent failed to surface the rollback option during the incident. [9] ↗
Replit says the incident predated its new separate development and production database system. It outlined stronger isolation and a planning mode to help users avoid letting an agent change live state. [9] ↗
