Climate tech investors near Palo Alto

Climate investing on the Peninsula has a longer memory than most people assume. Firms on Sand Hill Road poured money into solar panels, biofuels and batteries in the late 2000s, lost a lot of it and then came back a decade later with new tools and a more careful playbook. Stanford, meanwhile, built a whole school around sustainability and now funds research projects with commercial potential.

This guide explains how climate and energy investing works, profiles local firms in the terms they use to describe themselves and walks through the Stanford programs that feed new companies. It is not a ranking. We name only firms whose focus we could confirm on their own sites or in recent reporting. For the basics of how venture funds work, start with our venture capital guide.

Why climate investing is different

A software startup can reach revenue with a few engineers and a cloud account. A company making green cement, a new battery chemistry or a geothermal plant usually cannot. It may need a pilot plant, then a demonstration plant, then a first commercial facility before it can show investors real economics. Each step costs more than the last and takes years.

That shapes who invests and when:

• Seed and Series A money often comes from venture firms comfortable with science risk, plus university and government grants.
• Growth rounds may bring in corporate investors from energy, chemicals or automotive companies that want early access to the technology.
• First-of-a-kind plants frequently need project finance, government loans or debt, because venture equity alone is too expensive for steel and concrete.
• Software climate companies, such as carbon accounting or grid analytics tools, look more like normal software deals.

People in the field talk about a "valley of death" between a promising lab result and a plant that banks will finance. A large part of climate investing is figuring out who carries a company across that gap.

Cleantech 1.0 and the second wave

Between roughly 2006 and 2011, venture firms around Silicon Valley invested heavily in clean technology. Our page on Kleiner Perkins covers one of the best known examples. The firm raised a green growth fund of about $500 million around 2008. Partner John Doerr became a prominent voice for clean energy. Returns from cleantech across the whole industry were mixed. Several companies that had raised large sums failed when cheap solar panels from overseas and falling natural gas prices squeezed their markets. Solyndra, a Fremont solar maker, went bankrupt in 2011 and became the symbol of that era.

The second wave began in the late 2010s and grew quickly. Its investors learned some lessons. Many now stage hardware bets more carefully, lean on grants and debt for capital-heavy steps and pair climate goals with clear cost advantages. Software, sensors and AI also make some climate businesses cheaper to start than they were 15 years ago.

Local firms that invest in climate

These firms have offices on Sand Hill Road or in downtown Palo Alto and describe climate or energy as part of their focus. Each has its own profile page on this site.

Khosla Ventures

Vinod Khosla founded Khosla Ventures in 2004. In its first decade it was best known for clean technology. By 2013 it had invested in more than 70 cleantech companies in areas such as biofuels, batteries, cement and new materials. Some failed, as did many cleantech startups of that period. The firm kept going. Its website shows newer climate companies in low-carbon cement and geothermal energy. Coverage of its fundraising has noted interest in fusion power. It describes its stages as seed to Series A.

DCVC

DCVC began as Data Collective in 2010 and works from 270 University Avenue in downtown Palo Alto. It calls itself a deep tech firm and says it has "one of the longest records of climate tech investment of any VC firm in the world." Its funds cover climate alongside AI, biology, space and defense. DCVC Bio, set up in 2018, covers life sciences, agriculture and industrial biology, which overlaps with climate in areas like food and materials.

Felicis

Felicis sorts its investing into four areas on its website: AI, cybersecurity and defense, global resilience and energy and health and bio. Most of its deals are at seed or Series A, by its own count. Its energy and resilience work sits next to software bets, which suits founders building software for the grid, insurance or supply chains.

Kleiner Perkins

Kleiner's clean energy chapter is history now. Its recent funds are aimed largely at artificial intelligence. John Doerr, still listed as chairman, has stayed involved in climate through philanthropy, including the gift that named Stanford's sustainability school.

Investors based elsewhere

Several of the largest climate-only funds are not on the Peninsula. Breakthrough Energy Ventures, backed by Bill Gates and other investors, is based in the Seattle area. Many climate specialists work from San Francisco. Founders in Palo Alto routinely pitch them by video and meet in the city once talks get serious.

Stanford's climate pipeline

Stanford opened the Doerr School of Sustainability on September 1, 2022, its first new school in decades. John and Ann Doerr gave $1.1 billion. With other gifts the school launched with $1.69 billion in funding. The school folded in the old School of Earth, Energy and Environmental Sciences along with the Precourt Institute for Energy and the Woods Institute for the Environment.

Two programs inside or alongside the school matter most to founders.

The Sustainability Accelerator

The accelerator funds Stanford projects meant to move research toward real-world use. According to Heatmap's 2024 report, its 2022 request for proposals set three tiers: up to $100,000, up to $400,000 and up to $1 million, for projects lasting three months to a year. The first cohort had 31 projects. In 2024 it chose 16 projects for its first flagship focus, greenhouse gas removal. Materials scientist Yi Cui is faculty director. This is grant funding inside the university, not a venture fund, but it can produce companies that later raise venture rounds.

Ecopreneurship

In 2023 the Doerr School and the Graduate School of Business launched Stanford Ecopreneurship, funded by the Benioff Ecopreneur Fund. It includes a summer immersion program, support for internships at early climate companies and one-year fellowships for graduating students who start environmental ventures. It builds on the Precourt Institute's Stanford Climate Ventures class and resources from the TomKat Center.

The local energy context

Palo Alto is an unusual place to build energy companies because it runs its own utility. City of Palo Alto Utilities sells electricity, gas, water and fiber. Its rebates for heat pumps and induction stoves are among the most generous in the region. Our guide to solar and batteries in Palo Alto explains how rooftop solar is credited here. Stanford also runs its own heating and cooling plant, described on our Central Energy Facility page. Neither is a venture program, but both give founders nearby examples of electrification at scale.

Pitching climate investors

1. Show the cost curve. Investors want to know when your product beats the incumbent on price, not only on emissions.
2. Map your capital stack. Explain which steps venture equity pays for and which will need grants, debt or project finance.
3. Name your first customer. Utilities, industrial buyers and governments move slowly. A signed pilot or letter of intent counts for a lot.
4. Know the policy risk. Tax credits and grant programs change with each administration. Show that the business survives without them.
5. Pick partners with sector depth. Ask how many climate companies the partner has backed and how those companies handled their first plant.

Our guides to pitching investors and term sheets cover the general process.
