Frequently asked

Q1

Does a climate tech startup need a climate tech-focused investor?

No. Most of the 2,130 are generalist funds with a handful of climate tech deals; a focused thesis matters mainly at pre-seed and in capital-intensive sub-sectors. Look for the partner who led the fund's last climate tech deal, not for the word in the fund's name.

Q2

How many investors do founders contact to get meetings?

Founders in our Raise Benchmarks reached 45 to 900 investors per round. Besample reached 900 investors for 55 first meetings. Climate tech rounds are crowded on both sides, so targeting matters more than volume.

Q3

How do I get a warm intro to a climate tech investor?

Fundraisly's Warm Intro maps your team's LinkedIn connections against every investor in this database and shows which of these funds and angels a colleague can introduce you to.
