Vibe coding startup Lovable’s latest funding round values the firm at $6.6 billion and includes U.S. VC firm Accel, sources with knowledge of the deal told CNBC.

That figure is more than triple the $1.8 billion valuation the Swedish AI company achieved after closing its most recent funding round in July. It’s Lovable’s third in 2025 and follows a breakneck year of growth that’s seen it become one of Europe’s most valuable startups.

Accel was participating in the round, both sources said, which has not been previously reported.

U.S. investor Khosla Ventures is also participating in the latest round, one of the sources told CNBC.

Founded in 2023, Lovable reported $200 million in annual recurring revenue (ARR) in November, just under a year after achieving $1 million in ARR for the first time.
