QSimulate

QSimulate is a Cambridge-based quantum molecular simulation company founded in 2018 by Garnet Chan and Toru Shiozaki that develops cloud-based quantum chemical simulation tools for pharmaceutical, materials, and chemical companies.

November 2025: Raised new seed financing bringing total funding to over $11M, and launched QUELO v2.3, a quantum-powered simulation platform for drug discovery.

In August 2025, QSimulate partnered with Mitsui & Co. and Quantinuum to launch QIDO (Quantum-Integrated Discovery Orchestrator), a quantum-enabled chemistry platform integrating QSP Reaction software with Quantinuum's InQuanto platform. The QSP platform enables quantum chemical simulations modeling thousands of atoms with state-of-the-art quantum chemistry methods, enabling first-of-a-kind simulations of ligand-protein interactions throughout the computational drug discovery pipeline. Strategic partnerships include Japan Tobacco for small molecule drug discovery acceleration.
