Replit secures $250M and debuts Agent 3, an AI agent that automates coding, testing and workflows for enterprises and developers.

Key Takeaways

  • $250M funding secured. Replit raised $250 million in a round led by Prysm Capital, reaching a $3 billion valuation.
  • Agent 3 launch. The company’s most autonomous AI software agent, built to extend runtime, self-test and automate workflows.
  • Enterprise adoption. Designed for developers and non-technical staff to accelerate software creation and automate business processes.

On September 10, 2025, Replit announced a $250 million funding round, led by Prysm Capital, with participation from Amex Ventures and Google’s AI Futures Fund. The investment boosted Replit’s valuation to $3 billion.

This comes after major revenue growth, with the company jumping from $2.8 million to $150 million in less than a year.

Launch of Agent 3: Replit Expands Its AI Toolkit

Alongside the funding news, Replit introduced Agent 3, its latest autonomous AI coding tool.

According to company officials, Agent 3 significantly expands on earlier versions:

Self-Testing Navigates application interfaces to test itself periodically
Code Improvement

Workflow Automation Builds custom agents and workflows for business tasks

CEO and founder, Replit

Are AI Coding Agents the End of Traditional Programming?

Replit’s strategy reflects a wider industry shift toward AI coding agents.

  • Founder Amjad Masad has predicted companies will soon operate without dedicated computer engineers, underscoring the disruptive potential.
  • Competitors such as Google DeepMind’s AlphaEvolve and open-source frameworks like Meta’s LLaMA are reshaping how AI development tools evolve.
  • Major funding rounds — such as OpenAI’s $6.6 billion raise at a $157 billion valuation — stress the pressure on startups like Replit to deliver results at scale.

The race to eliminate traditional coding roles through autonomous AI agents is intensifying.

“We invested in Replit because we believe its vibe-coding solutions have the power to transform how businesses build — by empowering non-technical employees with the tools to bring software products to life.”

- Kevin Weber

Vice President, Amex Ventures
