Breakthrough Energy backs companies developing the next generation of clean energy solutions. We invest in bold ideas, fund breakthrough technologies, and shape markets to accelerate innovation across the five major sources of emissions—manufacturing, electricity, agriculture, transportation, and buildings.
Founded by Bill Gates, Breakthrough Energy supports companies at every stage, from early discovery to large-scale deployment, using technology, policy, and market-driven solutions to make clean energy affordable and scalable.
We are an international company that supports a Fellowship for growth-stage entrepreneurs, channels exclusive deal-flow to investors, and partners with institutions to discover profit in solving global problems. As a community, we exist to lead the transition to a more just and regenerative economy.
The 400+ ventures in the Unreasonable Fellowship operate across more than 180 countries, have collectively generated $15 billion in revenue, raised $15.1 billion in financing, and are positively impacting the lives of more than 1.4 billion people.
Sound Unreasonable? We hope so. Because reasonable ideas seldom change anything.
First to believe. We lead pre-seed and seed rounds for founders who see a new market coming before it has a name. For twenty years, we've backed movements that grew into categories of their own, from Fitbit, Peloton, Blue Bottle, Duo, Ring, and HashiCorp to a new generation building in AI, biology, space, nuclear energy, robotics, and quantum computing. Over 70 founders have come back to build another company with us.
