Lovable has raised a $400 million Series C at a $13.3 billion valuation, with Menlo Ventures and the EU-backed Scaleup Europe Fund leading the round and Tencent among the participating investors. Founded in 2023, the Swedish startup provides AI tools that let users build websites and applications from natural-language prompts, and counts Adidas, Deutsche Telekom and Hearst Group among its enterprise customers. The funding follows Lovable's statement that annualized run rate revenue reached $500 million in June and that its platform now hosts 60 million projects attracting 900 million monthly visitors. The company operates in the fast-growing vibe coding market, where AI generates working software from plain-language instructions. Lovable previously raised $330 million in December at a $6.6 billion valuation, also led by Menlo Ventures with CapitalG as co-lead, and has said it built its own in-house AI model, signed a multiyear Google Cloud agreement in June, and backed Denmark's Atech as Europe seeks to build globally competitive AI companies.
