Replit.

Replit is a platform for building software by describing it. A user types what they want and an AI agent writes the code. The platform runs it. The editor, the runtime, the database, the authentication, and the hosting live in one system, so the distance from idea to deployed application is a single conversation.

The company was founded by Amjad Masad and Haya Odeh and is based in California. The homepage pitch is blunt: "Turn ideas into apps in minutes, no coding needed." The customers run from founders and product managers to enterprise teams that need SSO and SOC 2, and to working developers who use it because the loop from code to running software is short.

What they're building

The product centers on Agent 4, which Replit says "writes production-ready code, evolves it, and stays out of your way." Agents run in parallel on separate tasks, and a visual design surface called Infinite Canvas lets users direct design changes without writing code. Around the agent sits the infrastructure. Authentication, database, hosting, and monitoring are built in, along with more than 100 integrations including OpenAI, Stripe, and Google Workspace.

The distinction from other coding tools matters. Most of them produce text and leave the user to assemble an environment around it. Replit gives the agent a computer where it can execute, test, deploy, and observe what it built. That step turns generated code into shipped software.

Why we backed the founders and team

AI now writes a growing share of the world's code, but code is not a product until it runs somewhere (provisioned, secured, deployed, watched). Replit spent years on that layer, executing arbitrary programs from anyone on the internet safely and packaging compilers, containers, and databases into something a browser tab can hold. None of it demos well, but all of it compounds.

When capable coding agents arrived, Replit was one of the few companies that could hand them a complete machine instead of a text box. Model, runtime, and infrastructure were joined into one loop and owned end to end. That is the assembly we look for. The number of people who can ship software is about to grow by orders of magnitude, and Replit built the factory floor before the workers showed up.
