Black Forest Labs was founded in 2024 by Robin Rombach, Andreas Blattmann, Patrick Esser, and Dominik Lorenz—the core researchers behind Stable Diffusion and latent diffusion models at LMU Munich and Heidelberg University. After leaving Stability AI, they founded Black Forest Labs in Freiburg, Germany to push frontier image generation research. The company emerged from stealth in August 2024 with the FLUX.1 model suite and a $31M seed round.
