About O2h Ventures

O2h Ventures runs UK tax-advantaged funds that invest in biotech and life-science companies. Its funds use the EIS and SEIS tax schemes, so they suit UK taxpayers who qualify for those reliefs. The firm warns that investors could lose all of what they put in.

  • Human health SEIS fund: backs seed-stage companies working on novel drug discovery, along with enabling services, tools and AI technologies.
  • Seven Sisters Human Health EIS Growth Fund: targets growth-stage UK biotech firms, holding a portfolio of unquoted and AIM-listed companies.

Who it works with

UK biotech and drug-discovery companies, and investors who are high net worth or sophisticated. Prospective investors must self-certify their status before viewing the offers.

Key facts

  • Country: United Kingdom
  • Tax schemes: EIS and SEIS
