Replit

Replit is a browser-based software development platform that lets users write, run, and deploy code in dozens of programming languages, with a growing focus on AI-assisted code generation through its Replit Agent. Used by millions of developers and students worldwide, the platform is pioneering a vision where natural language prompts can build and ship complete applications. In September 2025 Replit raised $250M at a $3B valuation, led by Prysm Capital with Amex Ventures and Google's AI Futures Fund, amid rapid growth in its agentic app-building business (~$150M annualized revenue).
