Lovable is reportedly in talks to raise $300 million, which would double its valuation to $13.2 billion, up from $6.6 billion in December. This funding round, expected to be led by Menlo Ventures, comes as the less-than-three-year-old startup achieved a $500 million annualized revenue run rate in June. The funds will likely support the expansion of its AI-powered vibe-coding platform, which serves individual users and enterprise clients like Workday and Nvidia.
