Black Forest Labs Seeks $4 Billion Valuation in New Funding Round

September 29, 2025
German AI startup Black Forest Labs is in talks to raise $200-$300 million at a $4 billion valuation, according to the Financial Times.

Black Forest Labs is reportedly in discussions to raise between $200 million and $300 million, aiming for a valuation of approximately $4 billion. This development underscores the growing investor interest in AI technologies, as reported by the Financial Times.

The German startup, known for its advanced image generation capabilities, has previously secured funding at a $1 billion valuation. Black Forest Labs, which launched in August 2024, is one of the few European companies developing proprietary AI models. Its flagship Flux models are designed to generate realistic images from text inputs and adapt existing images, making them a strong competitor in the visual AI market.

The company has collaborated with Paris-based Mistral to provide image creation tools and has made some of its AI systems available under open-source licenses. Black Forest Labs' technology is already being integrated into products by major companies like Adobe and Meta, further solidifying its position in the industry.
