Breakthrough Energy Ventures

About

Breakthrough Energy Ventures (BEV) is a climate-focused venture capital firm founded by Bill Gates in December 2016 ¹. The firm is headquartered in Kirkland, Washington ². BEV was created as a for-profit, private-sector investment vehicle emerging from the Breakthrough Energy Coalition, which Gates announced at the 2015 United Nations Climate Change Conference with 28 high-net-worth investors from ten countries ¹.

The founding coalition includes some of the world’s wealthiest individuals: Jeff Bezos, John Doerr, Vinod Khosla, Richard Branson, Jack Ma, Mukesh Ambani, Michael Bloomberg, John Arnold, Reid Hoffman, Mark Zuckerberg, Masayoshi Son, and Abigail P. Johnson, among others ³⁴.

The firm has raised more than $3.5 billion in committed capital across multiple funds ⁵. BEV Fund I launched in 2016 with $1 billion ¹. BEV Fund II raised approximately $1 billion in 2021 ⁶. BEV Fund III closed at $839 million in July 2023 ⁷. The firm also raised a $555 million Select Fund focused on later-stage growth investments and follow-on funding for existing portfolio companies ⁸. Rodi Guidero serves as Executive Director of Breakthrough Energy and Managing Partner of BEV, overseeing more than $5 billion in committed capital and 160+ portfolio companies across the broader Breakthrough Energy platform ⁹.

The firm’s scientific leadership team was established in 2017 with the hiring of Eric Toone (former ARPA-E founding member and Duke University professor) as Executive Managing Director and science lead, and David Danielson (former DOE Assistant Secretary and ARPA-E’s first employee) as Managing Director for science ¹⁰. Carmichael Roberts co-leads the investment committee and is recognized as one of the world’s top climate-tech venture capitalists ¹¹.

BEV is distinguished by its 20-year investment horizon — roughly double the typical venture capital timeline — reflecting the understanding that energy technology commercialization takes longer than software ¹²¹. To be eligible for BEV investment, a startup must demonstrate scientifically sound technology with the potential to reduce annual global greenhouse gas emissions by at least 500 million metric tons ¹.

Stated Thesis

Breakthrough Energy Ventures publicly describes its mission as financing, launching, and scaling companies that will eliminate greenhouse gas emissions throughout the global economy ⁴. The firm organizes its investment focus around what it calls the “Five Grand Challenges” — the five sectors responsible for the vast majority of global emissions ⁴:

1. Electricity — fusion, geothermal, grid infrastructure, energy storage, renewables
2. Manufacturing — steel, cement, hydrogen, carbon capture, critical minerals
3. Transportation — electric aviation, cargo ships, battery innovation, low-carbon fuels
4. Agriculture & Food — alternative proteins, sustainable farming, methane reduction
5. Buildings — HVAC, insulation, sustainable materials, building management

Bill Gates has stated: “It’s hard to get any new technology from the lab to the market. It’s especially hard with energy, because energy systems are so slow to change” ¹². Gates has also emphasized that “BEV is also bringing together a unique mix of risk-tolerant and patient investors who are committed to accelerating the commercialization of new energy technologies” ¹².

The firm states that it invests in “visionary entrepreneurs building companies that can have a significant impact on climate change at scale” and is “committed to investing patiently in developing new ways to live, eat, travel, and build” ⁵.

Inferred Thesis

Based on 30 verified portfolio investments (of 120+ total portfolio organizations per Crunchbase ⁵), BEV’s actual investment behavior reveals the following patterns:

Sector distribution: The portfolio is heavily concentrated in energy and industrial decarbonization. Based on the verified investments: electricity/energy generation (fusion, geothermal, grid) accounts for approximately 10 of 30 verified investments (33%); manufacturing/materials (steel, batteries, recycling) accounts for 7 of 30 (23%); transportation (aviation, EVs) accounts for 5 of 30 (17%); agriculture/food accounts for 3 of 30 (10%); buildings accounts for 2 of 30 (7%); carbon capture/removal accounts for 3 of 30 (10%). This sample represents roughly 25% of the full portfolio; percentages should be treated as directional.

Stage distribution: BEV invests across the full venture lifecycle, from seed through growth. Check sizes range from $500K to $50M ¹³. The firm primarily invests at Series A, with significant seed and Series B activity ⁵. The $555 million Select Fund targets later-stage follow-on investments for portfolio companies requiring capital for demonstration projects and scale-up ⁸.

Geographic focus: The portfolio is overwhelmingly US-based, with particular concentration in the Boston/Cambridge, MA cluster (Commonwealth Fusion Systems, Boston Metal, Verdox, Form Energy) and the San Francisco Bay Area (Heirloom, Lilac Solutions, Antora Energy). The firm also has a European presence through Breakthrough Energy Ventures-Europe, a partnership with the European Investment Bank and European Commission ¹⁴. Heart Aerospace (Sweden) represents international portfolio exposure ¹⁵.

Deep-tech bias: BEV invests almost exclusively in hardware-intensive, science-based companies. The portfolio includes fusion energy (Commonwealth Fusion Systems, Pacific Fusion, Zap Energy), next-generation batteries (QuantumScape, Form Energy), novel steel production (Boston Metal, Electra), hydrogen production (Electric Hydrogen), and geothermal (Fervo Energy). Software-only or marketplace companies are largely absent.

Mega-round participation: BEV participates in some of the largest rounds in climate tech, including Pacific Fusion’s $900 million Series A ¹⁶ and Commonwealth Fusion Systems’ $1.8 billion Series B ¹⁷.

Co-investor patterns: Frequent co-investors include Khosla Ventures, Lowercarbon Capital, DCVC, General Catalyst, Capricorn Investment Group, and Prelude Ventures. BEV, Khosla Ventures, and DCVC launched a $300 million coalition to back climate tech ¹⁸.

Notable gaps: Despite claiming “alternative proteins” as an investment area, verified investments in food/agriculture are relatively few compared to energy and manufacturing. The firm’s strongest revealed preference is for hard physics and chemistry-based solutions to energy production and industrial processes.

In Their Own Words

Bill Gates, on BEV’s founding rationale: “It’s hard to get any new technology from the lab to the market. It’s especially hard with energy, because energy systems are so slow to change” ¹².

Bill Gates, on the investor coalition: “BEV is also bringing together a unique mix of risk-tolerant and patient investors who are committed to accelerating the commercialization of new energy technologies” ¹².

Bill Gates, on industry partnerships: “Industry partners like Total understand the energy business better than anyone else. They know how to deliver energy solutions reliably and affordably at scale” ¹².

John Arnold (BEV board member), on the scientific team: “BEV’s vision to transform the energy market requires the deep in-house scientific expertise that Eric and David provide” ¹⁰.

Eric Toone, on BEV’s approach: “It’s a little bit different. With a moonshot, you have a singular goal in mind, and then you build those technologies to make that goal. At BEV, there isn’t a singular goal like clean tech. We invest in a number of different technologies” ²⁸.

Eric Toone, on the scale of the challenge: “It’s time to start accepting reality and that we’re not going to be able to do this fast enough, the ship is too big, it’s too hard to steer” ²⁹.

Eric Toone, on energy: “Energy is Prosperity” ³⁰.

Carmichael Roberts, on fusion energy: “Achieving commercial, affordable fusion power would be one of the most transformative milestones in human history — delivering clean, limitless energy to help strengthen energy security and improve global living standards” ¹¹.

Carmichael Roberts, on Commonwealth Fusion Systems: “CFS is advancing fusion at a pace and scale that can turn this future into reality — providing a unique opportunity to shape the energy landscape, especially as AI and data centers are driving unprecedented demand” ¹¹.

Carmichael Roberts, on urgency: “It takes a while for the planet to cool down. That’s the harsh reality and the motivation — that we are running out of time” ²⁹.

What Founders Say

Val Miftakhov, CEO of ZeroAvia, on choosing BEV as an investor: “They’re working on some of the hardest problems that exist in the world on the sustainability agenda… we really wanted to bring them in as an investor and we found a match there. So we’re really grateful to Breakthrough Energy Ventures” ³¹.
