No public source ranks climate-tech angels, and most climate angel money moves through syndicates and networks rather than famous individuals. This page lists Climate Angels, Green Angel Syndicate and Planet Positive in no particular order, with the numbers each publishes and a link to where it says so, plus independent data on climate funding in 2026.
Why do climate angels invest through syndicates?
A syndicate pools several angels behind one lead in a single deal, and climate tech spans hardware, energy, materials and software. The sources below describe the structure but do not say why climate investors favor it. They do show the scale: their AngelList pages list typical investments of $128,000 for Planet Positive and $156,000 for Climate Angels. The pages do not say how much an individual member puts into each deal.
Climate syndicate data is thin. Climate Angels' AngelList page has no description text, and Planet Positive's page notes that private investments may not be included yet. The figures below are what each group publishes, not audited records, and each source is dated so the age of the numbers is visible.
What does the climate funding market look like in 2026?
The independent numbers come from CTVC, whose H1 2026 report, published in July 2026, draws on Currence data. It counted $26.1 billion of climate-tech venture investment in the first half of 2026, up 55 percent on the first half of 2025 and the strongest first half since 2022. Deal count fell 25 percent to a five-year low, and the ten biggest deals took 42 percent of all funding. Low-carbon data centers made up 34 percent of the total, and Series C reached a record $10.5 billion. The article does not cover seed or pre-seed rounds.
The pattern in those figures is capital concentrating in fewer, larger deals, and the groups below sit inside that market.
Which climate angel groups publish their numbers?
Climate Angels
Inc42 reported in November 2020 that the Noida-based GoMassive Earth Network launched Climate Angels as an early-stage investment syndication platform for pollution reduction and climate tech. GoMassive was founded in 2017 by Shailesh Vickram Singh. Its AngelList page lists Singh, Vivek Sekhar and Vinutha Raju on the team, a typical investment of $156,000, about 10 expected deals a year and 11 unique LPs.
Green Angel Syndicate
Green Angel, in the UK, says on its own site that it invests in climate technologies with potential for both climate impact and financial return, originates and screens more than 1,000 opportunities a year, and has deployed over £60 million, with four exits to date. Portfolio companies it names include NatureMetrics, DEScycle and Qflow. The site describes an EIS Climate Change Fund, and says it is authorised and regulated by the Financial Conduct Authority and intended for professional investors. Private Equity Wire reported in June 2021 that Nick Lyth is its founder and chief executive and called it one of the largest active angel syndicates in the UK.
A third-party profile adds more. Startups Magazine reported in July 2024 45 companies in the portfolio, a pace of typically 7 to 10 new companies a year, and more than 350 specialist investor members in the syndicate. It dates the EIS Climate Change Fund to 2020. The UK government's page on the Enterprise Investment Scheme sets out the reliefs that such a fund targets: 30 percent income tax relief on up to £1 million a year, capital gains tax exemption on shares held at least three years, and loss relief.
Planet Positive
Its AngelList page lists Anke Huiskes and Kirsti Chou as the team, a typical investment of $128,000, about four expected deals a year and 44 unique LPs who have invested. Listed investments include Vaayu, The Shellworks and Polar Night Energy. HackSummit's undated list of 24 climate syndicates describes it as backing climate tech in the US and Europe at pre-seed and seed. The same list is a place to look for a regional group, from Italy to Australia, though it carries no publication date and the groups on it were not each checked for current activity.
What do the groups' own numbers say about pace?
Taken together, the published figures describe selective funnels. Green Angel says it screens more than 1,000 opportunities a year, while Startups Magazine puts its new investments at 7 to 10 a year. Planet Positive's page expects about four deals a year and Climate Angels' about 10. Those expectations come from the groups themselves and may not match their actual pace, and the AngelList pages may omit private deals.
For Australian climate companies, Climate Salad, a community of Australian climate technology entrepreneurs, mentors and investors, lists 138 climate-tech investors and 812 climate-tech companies in its directories as of October 2026.

Frequently Asked Questions
Q:Who is the top angel investor in climate tech?
No public source ranks them. The groups here are listed in no particular order because each publishes different numbers, and none of the sources compares them. HackSummit's list is a curated directory, not a ranking by results.
Q:How much do climate angel syndicates invest?
AngelList pages show typical investments of $128,000 for Planet Positive and $156,000 for Climate Angels. The Green Angel pages cited here state no typical check, and its site says it is intended for professional investors. These describe different structures, so compare them with care.
Q:What is the UK EIS and why do climate funds mention it?
The Enterprise Investment Scheme gives UK taxpayers tax reliefs for investing in qualifying early-stage companies. The government's page describes 30 percent income tax relief on up to £1 million a year, capital gains tax exemption on shares held at least three years and loss relief. Green Angel's own site notes that the availability of relief depends on the company invested in keeping its qualifying status.
Q:Are these groups still active?
Dates vary. Inc42's report on Climate Angels is from November 2020, Private Equity Wire's profile of Green Angel from June 2021, and HackSummit's list is undated. Planet Positive's AngelList page notes that private investments may not be included, so a group's current focus and pace are best read from what it publishes now.
