Black Forest Labs raises $300M to scale visual intelligence & R&D

Black Forest Labs has closed a major growth round, raising $300 million in a Series B led by AMP and Salesforce Ventures, valuing the Freiburg- and San Francisco-based lab at about $3.25 billion post-money. The funding follows an earlier, previously unannounced Series A and lifts total capital raised to more than $450 million.

The company — founded by the researchers who helped build modern latent diffusion methods — has positioned its flagship family of multimodal models, FLUX, at the centre of an emerging commercial market for visual intelligence. In under two years Black Forest Labs’ models have gained wide adoption: they sit among the most-downloaded text-to-image systems on public model hubs and are embedded into production workflows at major enterprises.

Management says the new capital will accelerate core research, scale infrastructure and expand hiring to meet growing demand for operational AI systems. CEO and co-founder Robin Rombach described the raise as “fuel for expanding FLUX’s research and enterprise footprint” and signalled heavier investment in model reliability, fine-tuning for customers and low-latency deployment tools.

Investors in the round and prior backers reflect a mix of strategic and financial support. The announcement names participation from Andreessen Horowitz (a16z), BroadLight Capital, Creandum, Earlybird VC, General Catalyst, Northzone and NVIDIA, alongside returning and new institutional names including Temasek, Air Street Capital, Bain Capital Ventures, StepStone Group, Visionaries Club, S32 Ventures, Notion Capital, European Tech Collective, Shutterstock, QuantumLight Capital, Canva, Figma Ventures, Cherry, Adobe Ventures, Deutsche Telekom's T.Capital, LEA Partners, SV Angel, Lux Capital, Samsung Next and Headline. Angel participants listed include Nico Rosberg, Guillermo Rauch, Michael Ovitz, Mati Staniszewski and Clem Delangue.

Industry partners have already embedded FLUX capabilities into creative and enterprise stacks. The company cites integrations with Adobe, Canva, Deutsche Telekom and Meta as evidence of commercial traction — a signal that customers are moving from experimentation to mission-critical uses for visual AI. Investors emphasised the combination of frontier research and fast productisation as the rationale for backing the team.

Beyond the immediate hiring and R&D plans, the round highlights a broader market trend: enterprises are prioritising models that can both generate high-fidelity images and supply robust visual understanding for search, moderation, product design and workflows. As demand for openly accessible, high-performance multimodal systems grows, Black Forest Labs intends to push FLUX further into production-grade tooling and enterprise integrations.
