Lovable, a Swedish vibe-coding startup, is in talks to raise $300 million at a valuation of $13.2 billion — exactly double the $6.6 billion valuation the company achieved last December, Sifted reported. Menlo Ventures, a firm that announced its latest $3 billion fund last month, is expected to lead the round, according to the report.

The less-than-three-year-old startup hit $500 million in annualized revenue run rate in June.

Lovable’s users include founders, individual designers, and salespeople building websites and e-commerce storefronts. The company also sells its vibe-coding tool to large enterprises, including Workday, Asana, and Nvidia.

Vibe coding, which allows users to build software simply by describing it, is by far the most popular and lucrative use case for AI. Other high-profile vibe-coding startups include Replit, valued at $9 billion in March, and Factory, a startup that helps enterprises develop AI agents, which raised $150 million at a $1.5 billion valuation in April. Meanwhile, Cursor, which offers vibe coding for developers, was acquired by SpaceX for $60 billion last month.
