Axiom addresses the reasoning bottleneck holding back breakthrough progress in science, finance, and engineering. The world's hardest problems—drug discovery, quantitative trading strategies, software verification—aren't constrained by data or compute, but by reasoning capability itself. By training AI on verified mathematical proofs rather than human preference, Axiom is building models capable of the rigorous and verifiable thinking these intelligence-constrained domains demand.Initial Investment2025Axiom addresses the reasoning bottleneck holding back breakthrough progress in science, finance, and engineering.
