Where it
all started


The Idea is Born

In 2013, whilst doing her PhD in Biomedical Engineering at Oxford, Katerina presented for the first time the idea behind Oxford Heartbeat to a wider audience at the Falling Walls Conference on Future Breakthroughs in Science and Society, and won the title “Young Innovator of the Year”.


Company Incorporated

Oxford Heartbeat was incorporated on 14th July 2015.


Our First Grant

Our first (of many) Innovate UK grants. This grant was to explore the idea (Proof of Market), and gave us the opportunity to interview 34 clinicians to understand the clinical need.


Our First Fellowship

We joined the Royal Academy of Engineering Fellowship programme. Awarded another Innovate UK grant to develop a Proof of Concept for cerebral stenting and received an NHS Innovation Award from Health Enterprise East (HEE).


Best UK Health Startup

Oxford Heartbeat is named Best UK Healthcare Start-up of 2018 by WIRED.



We are legitimately certified as a medical device company. Obtained ISO13485 certification as a medical device company and passed a BSI audit with only two minors (for those who don’t know, that’s no easy feat).


Clinical Trials

We received the prestigious AI in Health and Care Awards from NHSx and NIHR (one of 42 winners out of ~530) and this funds our prospective clinical trial. Also we had our first installation of PreSize® at St George’s hospital London.



PreSize® is used in real world clinical settings. We obtain the CE mark, and our declaration of conformity signed. First live patient in Leeds Teaching Hospital. The team hits double digits.



We are featured by The Times as a prominent AI start-up. 100 patients and counting participating in the PreSize® clinical trial, shown in action on the BBC.
