Prior Funding
This isn’t their first cash infusion. Black Forest Labs had a previously unannounced Series A led by a16z, with BroadLight Capital, Creandum, Earlybird VC, General Catalyst, Northzone, and Nvidia joining in. That brought their total raised to over $450 million, per the official announcement and Crunchbase data.
Company Background
Founded in 2024 in Freiburg, Germany—now Germany's most valuable AI startup—with a lab in San Francisco, the company builds open-source AI models for image generation and editing, like the FLUX series. Its co-founders, Robin Rombach, Patrick Esser, and Andreas Blattmann, previously worked on Stability AI’s Stable Diffusion. SiliconANGLE noted their models power tools at Adobe, Canva, Meta, Microsoft, and others, with millions of users.
Black Forest Labs plans to put the new money toward engineering for models that handle visual perception, generation, memory, and reasoning. The raise stands out in Europe, where AI funding hit $5.2 billion in Q3 2025—up from $2 billion a year earlier—though still behind North America’s $35.7 billion, according to Crunchbase.
