Leadership Team

We have a vision of a world where all surgery works exactly as planned.

Our foundations

We started in 2012, founded by a vascular surgeon and imaging scientist frustrated by the difficulty surgeons had visualising 'image guided' procedures and the resulting inconsistency of patient care. Since then, our team has been dedicated to building a future where all patients benefit from augmented surgical intelligence.

Find out about our incredible team that is working together to revolutionise surgical knowledge and patient care.
