AI app-builder Lovable raises $400M at $13.3B valuation

Lovable confirmed a new $13.3 billion valuation after raising an additional $400 million. The vibe-coding startup said it hit $500 million in annualized run-rate revenue in June.

Why it matters: Lovable's valuation and revenue growth show how fast AI app-building tools have moved from novelty to real revenue businesses, alongside similar surges at competitors like Cognition and Cursor. It's a signal that investors see AI-assisted software creation as one of the clearer near-term monetization paths for large language models.
