To find family offices investing in climate and cleantech, look for five signals: a stated climate domain, named climate companies in the portfolio, family wealth from energy, utilities, agriculture, or industrials, sector-savvy investment staff, and co-investments in rounds like yours. First decide whether you are raising for venture, project finance, or an impact fund.
Full disclosure: we sell a family office database, and the climate and cleantech list is one of our most-bought segments. This guide works with or without our file.
Why pitch family offices investing in climate?
Family offices can hold a position for a decade. They write checks between what angels and institutions do. They also bring operating knowledge when the family's wealth came from the sector.
Many of the offices most active in climate and cleantech do not publish a thesis page. So most of the work is identification.
How to find family offices investing in cleantech: five signals
- Stated investment domain. The office's website or LinkedIn says climate and cleantech. This is the strongest and rarest signal.
- Portfolio evidence. Named climate and cleantech companies on the website, in press releases, or in the decision-maker's LinkedIn activity.
- Wealth origin. Families whose wealth came from energy, utilities, agriculture, or industrials often invest in the transition of their own sector. Families with a philanthropic focus on the environment often run a parallel impact portfolio.
- People. A partner, principal, or investment director with a background in climate and cleantech. Search LinkedIn for family office titles plus sector keywords.
- Co-investment trails. Rounds in companies like yours where a family office appears next to funds. Trace the cap table backwards with public funding news.
Venture, project finance or impact: decide first
Climate investing splits into three types:
- Venture: early-stage technology.
- Project finance: solar, storage, and infrastructure.
- Impact funds.
Decide which you are raising for before you build the list, because the decision-maker is different for each. Our European family offices investing in climate post complements the USA one for a cross-border raise. Managers raising an impact fund can also read our family office database guide for emerging fund managers.
A one-week process to build your climate investor list
- Day 1: build the long list from a verified database filtered to climate and cleantech (ours tags the domain), plus the free family office directories.
- Day 2: read each website and the decision-maker's LinkedIn. Drop offices with no sector evidence.
- Day 3: rank by stage fit and check size where visible. Aim for 40 to 80 offices.
- Day 4 onward: write to the named decision-maker with the sector reason first, in batches of 20, and track replies.

Where the Active Family Offices database fits
Each family office in our file was verified as active (it runs a live website). Each record lists the website, LinkedIn page, location, investment domains, and named top decision-makers. Climate and cleantech is tagged where the office states it.
Most USA-region offices come with mail-server-verified work emails. Privacy law limits this for the EU, UK, and some other regions. Our post Climate and cleantech family offices shows ten offices from the file.
FAQ
How do I find family offices that invest in climate and cleantech?
Look for five signals: climate and cleantech stated on the website or LinkedIn, named climate companies in the portfolio, family wealth from energy, utilities, agriculture, or industrials, investment staff with a sector background, and family offices next to funds in rounds like yours. A verified database filtered to the domain speeds up the first step.
Which families are most likely to invest in climate?
Families whose wealth came from energy, utilities, agriculture, or industrials often invest in the transition of their own sector. Families with a philanthropic focus on the environment often run a parallel impact portfolio. A partner or investment director with a climate background is another strong sign that the office invests in the sector.
What kinds of climate deals do family offices invest in?
Climate investing splits into venture for early-stage technology, project finance for solar, storage, and infrastructure, and impact funds. The decision-maker is different for each, so decide which one you are raising for before you build the list. Then filter to offices whose website or portfolio shows that type.
How many family offices should I contact for a climate raise?
Aim for a ranked list of 40 to 80 offices. Read each website and the decision-maker's LinkedIn first, and drop offices with no sector evidence. Rank the rest by stage fit and check size where visible, then write to the named decision-maker in batches of 20 and track replies.
