BEIT builds a hybrid classical-quantum computational chemistry platform for early-stage drug discovery. The platform is designed to improve the fidelity of molecular simulations while remaining deployable on today’s classical infrastructure, not dependent on future quantum hardware. The platform supports key molecular modelling workflows including docking, rescoring, free energy calculations, covalent binding, and larger biomolecular interactions. In short, BEIT brings physics-grade molecular modelling into scalable production software for drug discovery.
