OSS

Space Tech·Growth

Oxford Space Systems was founded in 2013 by a team of serial entrepreneurs and engineers including Matthew John, Juan Reveles, Mike Lawton, Matthew Dreaper, and Vincent Fraux, with Sean Sutcliffe joining as CEO in 2019. Based in Harwell, the company develops deployable antenna systems for satellite missions using its flagship Wrapped Rib technology, which combines traditional space engineering with expertise from Formula One and textiles to enable parabolic reflectors to stow compactly for lightweight spacecraft. OSS has partnered with Surrey Satellite Technology on synthetic aperture radar payloads for the UK Space Agency and Space Norway, and was selected as a key supplier for the UK Ministry of Defence Oberon earth observation mission led by Airbus Defence and Space. The company has grown to over 100 employees and raised $31M from investors including Longwall Ventures, IQ Capital, Foresight Group, and NSSIF.

Cambridge GaN Devices

Hiring
Semiconductors·Series C

Cambridge GaN Devices was spun out from Cambridge University's Department of Engineering in 2016 by Dr Giorgia Longobardi (CEO) and Professor Florin Udrea (CTO). The fabless semiconductor company designs and commercialises gallium nitride power transistors and integrated circuits through its proprietary ICeGaN technology, enabling energy efficiency levels exceeding 99% and reducing energy consumption by up to 50% in applications including data centre power supplies and automotive electric vehicles. The technology builds on decades of GaN research at Cambridge, with Udrea's work recognised through induction into the ISPSD Hall of Fame. The company raised $32M in a Series C in February 2025, bringing total funding to over $60M from investors including IQ Capital, ParkWalk, BGF, Cambridge Innovation Capital, Foresight Group, and British Patient Capital.

TidalSense logo

TidalSense

MedTech·Growth

TidalSense was founded in Cambridge in 2013 and is led by chief executive Dr Ameera Patel, a physician and engineer, alongside co-founder and chief engineering officer Julian Carter. Its N-Tidal device reads the carbon dioxide waveform of ordinary tidal breathing, so a patient breathes normally into a handheld sensor for 75 seconds instead of performing the forced manoeuvre spirometry demands, and machine learning models classify the resulting curve. A clinician can assess four to six patients an hour rather than roughly one, and any healthcare professional can run the test after ten minutes of training. In March 2025 N-Tidal Diagnose became the first non-spirometry AI diagnostic device to receive CE marking under EU MDR (Class IIa) for COPD. It entered NHS service in September 2025 and has raised $40M in total, including $11M in grants and a $19M round led by Cross-Border Impact Ventures in July 2026.
