About
QSimulate is a Cambridge-based quantum molecular simulation company founded in 2018 by Garnet Chan and Toru Shiozaki. It develops cloud-based quantum chemical simulation tools for pharmaceutical, materials, and chemical companies. Its QSP platform runs quantum chemical simulations that model thousands of atoms, making possible first-of-a-kind simulations of ligand-protein interactions across the computational drug discovery pipeline. In August 2025, QSimulate partnered with Mitsui & Co. and Quantinuum to launch QIDO (Quantum-Integrated Discovery Orchestrator), a quantum-enabled chemistry platform that combines QSP Reaction software with Quantinuum's InQuanto platform. The company also has a strategic partnership with Japan Tobacco for small molecule drug discovery. In November 2025, QSimulate raised new seed financing that brought total funding to over $11M and launched QUELO v2.3, a quantum-powered simulation platform for drug discovery. QUELO v2.3 showed a 1,000x speedup for drug-protein interaction simulation compared with conventional methods. Customers include Google, Mitsui, and five top-20 pharmaceutical companies.
