£50,000 to £25m
Seed to growth
Oxford Science Enterprises (OSE) is an independent investment company based in Oxford, United Kingdom, created in 2015 to found, fund, and build companies from the University of Oxford's research. OSE operates through a unique partnership with the university - Oxford is a shareholder in OSE, and OSE typically receives half of the university's equity stake in each new spinout. This arrangement gives OSE preferred access to the university's intellectual property and academic talent across the sciences, engineering, and medicine.
OSE is structured as an evergreen, patient capital vehicle - a privately held company rather than a traditional VC fund bound by limited partnership agreements. It holds long-term investments without a fixed fund life, and can support companies from pre-seed through to exit without pressure to return capital on a set timeline. As of 2025, OSE is valued at approximately £1.1 billion ($1.45 billion) and has invested £0.6 billion in over 80 companies built on Oxford science. The firm has a team of 55+ people on the ground in Oxford, working directly with academics, departments, and students to identify commercial opportunities.
Mission
OSE's mission is to commercialise Oxford University's research by founding, funding, and building companies that can tackle major global challenges - and deliver market-leading returns for investors.
Goals
Values
OSE adopts a patient capital approach, recognising that the path from fundamental research to commercial scale takes time. Since OSE's founding in 2015, annual investment into Oxford spinout companies has grown from £135 million to £1.4 billion (in 2022), representing over half of all capital raised by UK university spinouts that year. OSE has brought in over 300 co-investors and facilitated more than £2 billion in total capital deployment into the Oxford ecosystem.
OSE was founded in 2015 as Oxford Sciences Innovation (OSI) by David Norwood, who had previously founded IP Group, the listed investor in UK university spinouts. The premise was to create a single, well-capitalised investment vehicle with preferred access to commercialise research from across all of Oxford's science departments - replacing the more fragmented, department-by-department model that had existed before.
The company raised an initial £600 million from international investors including Lansdowne Partners and Google Ventures. DeepMind founder Demis Hassabis and Google Ventures partners Tom Hulme and Krishna Yeshwant joined the advisory board. The company later rebranded to Oxford Science Enterprises, and in 2022 raised a further £250 million, bringing total equity funding to over £850 million.
In April 2025, OSE raised an additional £175 million ($232 million) in venture debt - a NAV facility led by Goldman Sachs and Deutsche Bank. This made it one of the first early-stage VC firms to secure bank financing of this kind. The firm's leadership changed several times in its early years before stabilising in September 2023 with the appointment of Ed Bussey as CEO and Jack Edmondson as the newly created Chief Investment Officer.

Jack Edmondson - CIO (appointed September 2023)
Other senior team members include Chris Chambers (Chairman), Jim Wilkinson (CFO), and David Norwood (co-founder).
OSE invests exclusively in companies built on or connected to University of Oxford research. The firm works across three sectors - life sciences, health tech, and deep tech - and goes beyond funding to provide hands-on operational support. This includes connecting founders with experienced management talent, providing access to co-investors, and offering lab and startup space (over 55,000 sq ft as of 2022). OSE also operates a Scientist-in-Residence programme and offers 12-month sabbaticals for Oxford academics developing spinout companies.
OSE is based in Oxford, United Kingdom, and its primary focus is on Oxford-originated companies. Most portfolio companies are UK-incorporated, with 71 of its investments based in the United Kingdom and a smaller number in the United States and elsewhere. OSE's investor base is international, including Google Ventures, Sequoia Capital, Tencent, Invesco, Lansdowne Partners, Aviva, Fulcrum Asset Management, and JIMCO (the investment arm of the Jameel Family).
OSE focuses on three high-growth sectors where Oxford has particular research strength:
OSE invests at the pre-seed and seed stages, typically as the first institutional investor in a new Oxford spinout. Investment sizes range from £50,000 to £25 million, and OSE provides follow-on financing for portfolio companies through to exit. The firm is actively focused on a core portfolio of around 40 companies at any given time, though total recorded investments exceed 110 (per third-party data from Tracxn and PitchBook). According to Tracxn, average deal sizes are approximately $5 million at seed and $22 million at Series A, though these vary considerably by sector. OSE works closely with Oxford University Innovation (OUI), the university's technology transfer office, which manages intellectual property and patent commercialisation.
First Light Fusion: Founded in 2011 as an Oxford spinout, First Light Fusion is developing a new approach to inertial confinement fusion energy using projectile technology. In April 2022, the company achieved fusion using its unique target technology - independently verified by the UK Atomic Energy Authority - having spent less than £45 million. The approach aims to offer a simpler and cheaper pathway to clean energy production than alternative fusion methods.
Oxford PV: A next-generation solar energy company developing perovskite-on-silicon tandem solar cells. Oxford PV set a world record for solar cell efficiency at 29.5% conversion (in 2020), compared with 15-20% for conventional silicon cells, and has continued working toward higher efficiency targets and commercial production.
Oxford Ionics: A quantum computing spinout that developed trapped-ion quantum processors. OSE was a founding pre-seed investor in 2019, providing venture building support from the earliest stage. Oxford Ionics was acquired for over $1 billion in 2025 - one of the largest acquisitions of a UK deep tech spinout.
OSE has raised over £850 million in equity from international investors since 2015. Key shareholders include Google Ventures, Sequoia Capital, Tencent, Invesco, Lansdowne Partners, Aviva, Fulcrum Asset Management, and JIMCO. Huawei invested £4.1 million in 2019 (approximately 0.7% of the fund at the time).
In April 2025, OSE raised £175 million ($232 million) in venture debt through a NAV facility led by Goldman Sachs and Deutsche Bank - one of the first secured bank financings for an early-stage VC of this type. OSE is structured as a permanent capital vehicle and expects to become self-financing as portfolio exits accelerate over the coming years.
