European vibe-coding platform Lovable has secured a $400 million Series C led by Menlo Ventures and the Scaleup Europe Fund, with participation from Regent and over a dozen other backers. The deal doubles the company's valuation to $13.3 billion in just six months, following a $330 million round at a $6.6 billion valuation co-led by Menlo Ventures and CapitalG last December.
Unlike pure narrative plays in the generative AI space, Lovable is backing its price tag with aggressive monetization. According to disclosures Lovable made to TechCrunch, the startup reached $500 million in annualized run rate (ARR) this June. The platform reports hosting 60 million projects that draw 900 million monthly visitors, underpinning that volume with a multiyear Google Cloud expansion that increased its compute infrastructure footprint fivefold.
Yet beneath the top-line momentum lies the central vulnerability of the vibe-coding sector: long-term retention and platform dependence. To avoid functioning merely as a fragile interface on top of foundation models that could render third-party wrappers obsolete overnight, Lovable operates an in-house trained AI model alongside standard frontier options while backing ecosystem players like Danish hardware startup Atech. For enterprise buyers and CTOs, the critical operational task is auditing natural-language coding tools to confirm whether mission-critical workflows run on defensible proprietary architecture or volatile pass-through APIs.
