The UK Innovation & Science Seed Fund, previously known as the Rainbow Seed Fund, is an early-stage venture capital firm dedicated to kick-starting promising technology companies developed at some of the UK’s largest publicly-funded research facilities.

We help build companies from great science developed in: public 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.
