Our Story

Arctoris was founded to solve a fundamental problem in drug discovery: biology has not kept pace with the scale, rigor, and data quality modern science demands.

Born out of the University of Oxford, our founders believed life sciences deserved the same industrial discipline that transformed aerospace and semiconductor manufacturing. Manual workflows, fragmented data, and inconsistent quality control were holding discovery back, especially as AI and data-driven approaches became central to R&D.

Our answer was not automation for automation’s sake, but industrialised biology.

At the heart of Arctoris is Ulysses®, our fully robotic, cloud-controlled discovery platform. Ulysses runs entire assay cascades across biochemistry, biophysics, cell biology, and structural biology, capturing every action, every parameter, and every datapoint in real time. The result is highly reproducible, FAIR-compliant datasets generated at a scale and consistency conventional CROs cannot match.

But technology alone is not enough. Arctoris operates as a Partnership Research Organisation (PRO), combining world-class scientists with a data-first automation platform to work as a true extension of our partners’ teams. We design bespoke experimental strategies, solve complex biological problems collaboratively, and deliver data that scientists, regulators, and machine-learning systems can trust from day one.

We don’t just scale experiments.

We scale certainty.
