42 is an AI research company building an autonomous AI Scientist that conducts scientific discovery through a continuous cycle of hypothesis generation, experimentation and real-world feedback. It operates without human intervention in complex, non-stationary environments across financial markets and scientific domains including human biology, neurotechnology and fundamental physics.

The company has developed a self-sustaining model in which AI generates both new knowledge and the capital to fund further scientific research. Its first application is in quantitative trading, where the system develops and executes strategies, using financial markets to test its capabilities under adversarial conditions and finance new discoveries. 42 is guided by the principle that the greatest scientific breakthroughs begin with the right questions.

42 brings together researchers and engineers with PhD-level expertise in quantitative finance, artificial intelligence and computational science. It operates across Europe and North America, with R&D hubs in Amsterdam and Montreal. The company was founded by Kirill Eves, with Mira Weiser as co-founder.
