An Early-Stage Venture Capital Fund

Building and Growing Technology Companies

Stemming From The UK’s Research Base


The Rainbow Seed Fund is backed by the Department for Business, Innovation and Skills and the Fund’s partners are 9 publicly funded research bodies, including STFC, BBSRC, NERC and Dstl. The Fund is independently managed by venture capital specialist Midven.

We help build companies from great science developed in laboratories, science and technology campuses and synthetic biology.

We hold investments in some of the UK’s most innovative companies, in areas as diverse as novel antibiotics, research into Alzheimer’s disease, “green” chemicals and airport security.
