Midven-RSF

The Rainbow Seed Fund (RSF) is an early-stage venture capital fund, managed by Midven, focused on commercializing breakthroughs from UK publicly-funded research organizations. It provides capital to small and medium enterprises developing innovative tools and products across diverse technologies. RSF aims to bridge the funding gap between initial start-up and sustainable growth, supporting development to proof-of-concept.

The Rainbow Seed Fund launched in May 2002 with initial government investment, addressing the "Valley of Death" in early-stage technology commercialization. Andrew Muir and Mark White independently manage the fund through Midven. Midven, established in 1990 by six entrepreneurs in the West Midlands, applies its investment expertise to nurture promising advancements.

RSF supports nascent technology companies originating from its partner research organizations or located at their science campuses. These enterprises leverage the fund’s investment to transition research into marketable solutions. The fund's vision is to foster high-potential UK technology businesses, ensuring scientific discoveries contribute to economic and societal benefit.
