German AI research and technology company Black Forest Labs has announced a $300 million Series B round at a $3.25 billion post-money valuation, which will accelerate its research and development.
- Founded in 2024 by Robin Rombach, Andreas Blattmann, and Patrick Esser, Black Forest Labs develops advanced visual-AI models that generate and manipulate images.
- Its systems, including FLUX.2, produce high-resolution photorealistic output, maintain consistency across characters and styles, and allow multi-reference image editing such as replacing objects or transferring visual styles.
- The models operate via API or self-hosted deployment, using diffusion-based architectures that interpret user intent rather than simply executing prompts. The technology is used in enterprise workflows on platforms like Fal.ai, Replicate, and TogetherAI, and integrated by companies including Adobe, Canva, Meta, and Microsoft.
"But these are early days. Looking ahead, we aim to develop models that unify visual perception, generation, memory, and reasoning—laying the foundations for visual intelligence," commented the Black Forest Labs team in a press release.
Details of the deal
- The Series B round saw support from Salesforce Ventures, AMP, a16z, NVIDIA, Northzone, Creandum, Earlybird VC, BroadLight Capital, General Catalyst, Temasek, Bain Capital Ventures, Air Street Capital, Visionaries Club, Canva Ventures, and Figma Ventures.
- Black Forest Labs will use the fresh Series B funding to accelerate its research and development toward next-generation visual-intelligence models, expand the infrastructure needed to train and deploy increasingly large FLUX models, and grow its teams across Freiburg and San Francisco.
- The company also plans to strengthen enterprise-grade capabilities and support deeper integrations with partners as demand for its visual-AI technology continues to scale.
