Lovable, an AI coding assistant startup, is in advanced discussions to raise $300 million in funding that would value the company at $13.2 billion, according to Sifted. Menlo Ventures is expected to lead the round.

The funding would roughly double Lovable's previous valuation, signaling investor confidence in the AI development tools market. Lovable positions itself as a platform that helps developers build web applications faster using AI assistance, competing in a crowded space alongside GitHub Copilot and other code generation tools.

The round reflects broader investor appetite for AI infrastructure and developer tools, even as venture funding has become more selective. AI coding assistants have captured significant mindshare in the startup ecosystem, with multiple companies pursuing different angles on how AI can accelerate software development workflows.

Lovable's valuation trajectory mirrors patterns seen in other AI infrastructure startups that have attracted substantial capital in recent years. The company appears to be capitalizing on growing demand for tools that reduce development time and lower barriers to entry for building web applications.

The funding environment for AI startups remains active despite broader economic uncertainty. Investors continue backing companies addressing developer productivity and enterprise software efficiency, viewing these as defensible markets with strong unit economics and recurring revenue potential.

Details on the round's exact timing and whether other investors are participating remain unclear. If completed at the reported valuation, the funding would position Lovable among the most valuable AI coding assistant companies, rivaling other players in the space that have achieved multi-billion-dollar valuations through investor backing and product-market fit.
