An investment firm backing climate-focused companies aiming to unlock decarbonisation at scale

AccelR8 is an investment firm that backs companies working on the transition to a decarbonised and resilient economy, describing its approach as unabashedly market-driven. It says it maps market needs and system dynamics to build investment theses around industrial sectors, then partners closely with founders on product and organisational development from the early stages of a company's formation. The firm also works with private, public and philanthropic partners toward what it calls a climate-positive future. In choosing founders to back, it looks for people focused on customer problems who can build products, close deals and form strong teams; in choosing companies, it looks for solutions capable of measurable greenhouse gas reduction within twenty years, with technology proven at an early readiness level, sound unit economics and a committed team with technical and commercial expertise.
