How many clean technology investors are there?
AngelMatch tracks 11,000+ investors in the clean technology market, making it the largest energy and sustainability category on the platform by a wide margin. That includes angel investors, venture capitalists, and private equity investors backing companies across energy, industrial technology, transportation, and related infrastructure. If you're not sure whether your company fits this category or a narrower AngelMatch market, start here. It's the broadest lens on the platform for anything touching energy, sustainability, or industrial technology.
The sector's funding backdrop is shifting toward discipline rather than growth-at-all-costs, and it's useful context before you start outreach. Silicon Valley Bank's 2026 climate tech report found that US venture investment in climate tech reached $29 billion in 2025, the third-highest year on record behind 2021 and 2022, even as deal activity slowed across most subsectors. The same report found that 52% of climate tech companies reduced their net burn year over year as gross margins improved, which tells you something concrete about what investors want to see right now: proof you can run lean, not just proof you can grow fast.
What stage and type of clean technology investors are in the database
Unlike most categories on AngelMatch, angel and individual investors are the largest single group here, with 7,500+ tagged to clean technology. Venture capitalists follow at 5,500+, and private equity investors at 4,000+. That mix matters for how you sequence outreach: a category this size, with this many individual investors, rewards a broader first pass rather than assuming every check has to come from an institutional fund.
Seed investors are the largest stage group, at 3,000+, followed by early stage venture at 1,500+ and pre-seed at 1,000+. Series A and Series B investors make up smaller groups, at 700+ and 400+, which reflects how many clean technology deals in the database sit at the earlier, angel-heavy end of the funding curve rather than the later institutional rounds.
Corporate venture capital and micro VC investors each add a smaller but meaningful slice, with roughly 300+ and 500+ respectively. If your product has an obvious strategic buyer, such as a utility, an industrial manufacturer, or an energy company, it's worth including a handful of corporate investors alongside the individual angels on your list, even though they typically move more slowly and diligence longer than a standard check.
Check sizes and dilution follow AngelMatch's standard ranges: angel investors write between $25,000 and $500,000, venture checks run from $2 million to $100 million or more, and typical early-round dilution sits between 15% and 25%. Given how heavily this category skews toward angel and individual investors, expect more of your early capital to come in smaller increments from multiple checks rather than one large lead, and plan your runway math around stacking several angel commitments instead of waiting on a single institutional close.
Where clean technology investors are based
The United States dominates this category more than most others on AngelMatch, with 6,500+ investors, well over half the total list. California and New York lead among states, and San Francisco and New York City are the top cities by a wide margin. The United Kingdom is a distant second by country, with England as its leading region and London its top city.
If California is where you're starting, don't stop at the state level. San Francisco alone accounts for a meaningful share of the state's clean technology investors, so a city-level search will surface names a broader California search buries on page four.
The United Kingdom is worth a dedicated pass rather than folding it into a general Europe search. It's the largest market outside North America in this category, concentrated heavily around London, and UK clean technology investors tend to have their own networks and event circuit that's distinct from the US scene, so a warm introduction from another London-based investor or founder carries more weight there than a cold email referencing your US traction.
Beyond the US and UK, Canada, Germany, and India round out the next tier, each with meaningful but smaller pools of investors. If you're building a list outside North America, don't expect the same density you'd find in California or New York. European and Indian clean technology investors are real but more thinly spread across more cities, so plan for a longer research phase to find the right handful rather than assuming a single hub city will have everything you need.
Who invests in clean technology right now
The list spans a genuinely wide range of backgrounds, from individual operators who invest personally to institutional venture and private equity investors with dedicated energy and infrastructure focus. As of 2026, investors tagged to clean technology in AngelMatch include Brett Berson in San Francisco, Allen Miller and Brandon Gleklen in New York City, Candice Brackeen in Cincinnati, Michel Lempdes in Paris, and Matt Cross in Vancouver, each filed under venture capital in the database alongside other tags such as private equity or angel and individual. That geographic and type spread is the point: this category doesn't cluster around one investor archetype the way some AngelMatch markets do.
Investors based outside the usual coastal hubs, such as Candice Brackeen in Cincinnati, are worth taking as seriously as anyone in San Francisco or London. Clean technology touches industries, like manufacturing and utilities, that are often headquartered in the Midwest and other non-coastal regions, so an investor based there may have sharper industry relationships than a generalist coastal fund, even if their name is less familiar.
Use the location, stage, and type filters above the table together, not separately, or you'll end up with a list too broad to work through efficiently. A Fundraising CRM is worth setting up before you start reaching out at this scale, since tracking status across a list this size by memory or a spreadsheet gets unreliable fast.
How to approach clean technology investors
Lead with unit economics, not just mission. Investors in this space have absorbed the same shift SVB documented across the sector: capital is more selective, and the founders getting funded are the ones who can show a credible path to healthy margins, not just a compelling reason the world needs their product.
Because angel and individual investors make up such a large share of this list, tailor your pitch accordingly. An individual investor writing a $25,000 to $500,000 check often wants to understand you and your reasoning as much as your spreadsheet. Don't assume every recipient wants an institutional-grade data room on the first email. Lead with a short, specific note about why this investor's background makes them a fit for what you're building, then follow with the numbers.
Be direct about policy exposure if it applies to you. Tax credits, permitting rules, and regulatory support for clean technology have shifted meaningfully over the past two years, and investors have grown wary of models that quietly assume today's policy environment holds steady. If your business is exposed to a specific credit or mandate, address it before they ask.
Reference the profitability shift directly if your numbers support it. If you've improved your gross margin or cut your burn rate over the last year, say so in plain terms and lead with it, since that's precisely the signal SVB's data shows investors are rewarding right now. Founders who can point to concrete margin improvement stand out against a pool of pitches still leading with growth metrics alone.
Plan for a longer close than a typical software raise, especially if you're stacking several angel checks instead of closing one lead investor. Clean technology deals in this database often involve more individual conversations than a typical venture round, and each one takes its own time to build trust and close. Once you've built your target list from the investor database, budget more calendar time for this raise than you would for a comparable software round, and treat the extra time as part of the plan rather than a sign something's wrong.
