San Francisco–based AI coding platform Replit has secured $250 million in new funding, propelling its valuation to $3 billion, nearly quadrupling from its previous $800 million mark.
The latest round, led by Prysm Capital, also attracted heavyweight backers including Amex Ventures, Google’s AI Futures Fund, a16z, Coatue, Y Combinator, Craft Ventures, and Replit co-founder Paul Graham.
The funding underlines investor appetite for AI-driven developer tools, particularly as Replit’s rapid growth signals strong demand for autonomous coding solutions.
Revenue Growth Outpaces Market Expectations
Replit’s performance has been nothing short of remarkable. In less than a year, the company’s annualized revenue skyrocketed from $2.8 million to $150 million, a 50x increase that has reshaped perceptions of AI’s commercial potential.
This explosive growth helped justify its near-4x valuation surge, as investors increasingly reward proven market traction over pure speculative bets.
The company’s tools are now used by more than 40 million developers worldwide, solidifying its position as a go-to platform for both professionals and learners experimenting with AI-driven code generation. With its recent entry into the Google Cloud Marketplace, Replit is widening its distribution footprint, making its products more accessible to enterprises and startups alike.
Autonomous Agents Reshape Software Creation
Alongside its funding announcement, Replit unveiled Agent 3, the latest evolution in its line of AI agents designed to automate coding workflows. Unlike earlier iterations, Agent 3 can run independently for up to 200 minutes, representing a 100x leap in autonomous capability since the company’s first model.
This breakthrough allows the AI to write, test, and even fix code without human intervention, effectively handling end-to-end development cycles. Where most coding assistants stop at suggestions or snippets, Replit’s new agent marks a step toward fully autonomous software engineering.
📣 It’s a very special day here at Replit- we are proud to introduce Agent 3, our most autonomous Agent yet 🔥
What's new with Agent 3:

The scaling pattern of these agents, each delivering an order-of-magnitude improvement, suggests exponential growth in capability. By crossing the three-hour autonomy threshold, AI systems like Agent 3 could soon deliver production-ready software projects, shifting how companies think about hiring, timelines, and cost efficiency in development.
Strategic Investors Signal Industry Confidence
The composition of investors in this funding round also tells an important story. Backers such as Google’s AI Futures Fund and Amex Ventures highlight the growing interest of established tech giants and financial players in platforms that complement their own AI strategies.
Google, for instance, is betting on ecosystems that extend the reach of its cloud and AI services, while Amex could see applications in fintech development.
By drawing in both strategic and traditional venture capital, Replit positions itself as not only a fast-growing startup but also a critical enabler of the AI-powered software economy. The funds will be directed toward expanding global operations, scaling product development, and accelerating innovation in autonomous coding technology.
