Europe’s favorite vibe-coding startup Lovable has confirmed previously reported whispers that it was raising another mega round at a $13.3 billion valuation. Lovable said on Wednesday that it has raised $400 million in a Series C round led by Menlo Ventures and the Scaleup Europe Fund, with more than a dozen other investors participating.

This new funding comes after Lovable hit $500 million in annualized run rate revenue in June, the startup told TechCrunch. Its previous round, announced in December, brought in $330 million at a $6.6 billion valuation and was also led by Menlo Ventures, with CapitalG as co-lead.

As the startup has grown — it now says it hosts 60 million projects that attract 900 million monthly visitors — so has its back-end needs and sophistication, the company says. Lovable, for instance, offers its own in-house trained AI model, as well as the usual frontier model options. In June, it signed a multiyear deal with Google Cloud, a fivefold increase in usage. Lovable has also backed other European startups, such as Danish startup Atech, which is building vibe-coding software that designs tech hardware.

Note: One of Lovable’s new Series C investors is Regent, the investment firm that also owns TechCrunch.
