Connecting entrepreneurs and companies with highly active business angels.

Investor / Business Angel Entrepreneur / Company

We work with entrepreneurs and companies seeking to raise finance by connecting them with highly active potential investors (‘business angels’), who frequently provide commercial experience and contacts, in addition to vital capital.

Oxford Investment Opportunity Network (OION) was established in 1994 as one of the UK’s first business angel networks. OION has a particular interest in companies with a strong barrier to entry, often patented; but will consider any company with a strong vision for growth and seeking investment from £200k to ~£2m. We link qualified Investors (High Net Worth, Sophisticated and Institutional) to companies with high growth potential.

Following the success of the OION 2015 & 2016 SEIS Funds, OION, as part of OION Ltd, is pleased to announce the launch of The OION Fund - investing in to both EIS & SEIS qualifying companies. For more information, please visit

The next investment meeting will be held at Oxford Martin School, Oxford at 4.30pm.
