Lovable, an AI-powered web development platform, has closed a $400 million funding round at a $13.3 billion valuation, according to TechCrunch. The raise comes on the heels of the startup hitting $500 million in annualized run rate revenue in June.

The company allows developers and non-technical users to build and deploy web applications using AI assistance. Lovable competes directly with other low-code and AI-assisted development platforms in a crowded market that includes players like Cursor, v0 by Vercel, and traditional low-code vendors.

This valuation represents significant momentum for the startup, which has rapidly scaled its revenue to half a billion dollars annually. The $400 million injection provides capital to fuel product development, expand its user base, and strengthen its position against well-funded competitors in the AI development tools space.

Lovable's growth trajectory reflects broader investor appetite for AI-assisted development platforms. The category has attracted billions in venture funding as companies seek tools that democratize software creation and accelerate development cycles. With substantial ARR and a substantial funding round, Lovable positions itself as a serious contender in reshaping how applications get built.

The startup's ability to reach $500 million ARR demonstrates strong product-market fit and customer willingness to pay for AI-powered development solutions. This new capital should accelerate Lovable's path to profitability and expansion into adjacent markets within the developer tools ecosystem.
