42 is an AI research company building an autonomous AI Scientist, a system for automating scientific discovery through a closed loop of hypothesis generation, experimentation, and real-world feedback, without human intervention. It operates in complex non-stationary environments across domains including human biology, neurotechnology, and fundamental physics, and in financial markets. 42 is based on the premise that scientific progress depends less on finding answers than on asking the right questions.

42 is built around a self-sustaining model in which an autonomous system generates both new knowledge and the capital needed to advance research. In science, it is designed to accelerate discovery and turn scientific insight into frontier technologies. In financial markets, it operates as an autonomous trader deploying capital in real time, serving both as an adversarial stress test for the system and the engine that funds the science.

42 brings together researchers and engineers across Europe and Canada. The company shares premises with Mila, the Quebec AI Institute, and collaborates closely with its research ecosystem.
