grubel is an AI research lab building specialized legal AI systems designed to handle complex, reasoning-intensive tasks beyond standard retrieval-augmented generation. The company automates a specialization loop that adapts models, agents, and harnesses to individual legal matters at test-time, allowing clients to deploy sovereign, case-specific AI models on private infrastructure. Founded by machine learning professors Moritz Hardt and Reinhard Heckel, the firm raised a €3 million pre-seed round led by Point Nine in September 2026. Prominent artificial intelligence pioneers and legal tech executives including Jeff Dean, Chris Ré, Ion Stoica, Gabe Pereyra, and Winston Weinberg participated as angel investors in the round.
