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

The less than three-year-old startup reached an annualized revenue rate of $500 million in June.

Lovable users include founders, individual designers, and sellers who build websites and e-commerce stores. The company also sells its vibration coding tool to large companies, including Workday, Asana, and Nvidia.

Vibe coding, which allows users to create 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 companies develop artificial intelligence 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.
