Frequently asked questions

How many Clean Technology investors are on RaiseHunt?

RaiseHunt currently lists 316 Clean Technology investors.

Are Clean Technology investors angels or funds?

Both. 261 are angel investors putting in their own money, and 55 are people making investment decisions at 10 firms.

Where are most Clean Technology investors based?

The largest concentrations are in San Francisco, Singapore and Paris.

What stage do Clean Technology investors invest at?

Most list Seed and Series A among the rounds they take part in.

How do I contact Clean Technology investors?

Every profile shows whether an email address is on file. The addresses themselves, along with AI matching and outreach, are in the RaiseHunt app.

Is the list of Clean Technology investors free to browse?

Yes. The directory and every profile page are free to read. Matching your own startup against them requires an account.

Do Clean Technology investors only back Clean Technology companies?

No. A focus area is a signal of interest, not a restriction. Investors usually list several, and the useful question is whether their existing portfolio looks like the kind of company you are building.

How do I know which Clean Technology investors are a fit?

Look at what they have already funded rather than what their profile says they like. Stage matters most, then sector, then geography. An investor who has never funded anything at your stage is unlikely to start with you, however well the sector lines up.

How long does raising a round usually take?

Longer than most first-time founders plan for. The work splits into building the list, running outreach, taking meetings, and closing, and each stage can stretch. Start before you need the money, not when the runway is short.

What do investors look at first?

The team and the problem, in that order, before the product. Early on there is rarely enough traction to argue from numbers alone, so the question they are answering is whether these particular people are likely to work this problem out.

Should I raise from one investor or several?

Several, in almost every case. A single backer concentrates the risk of the round collapsing if that one conversation goes cold, and a group brings more introductions later. Rounds are usually assembled from a lead plus others who follow.

How do I follow up without being annoying?

Follow up with new information rather than a reminder. A short note saying what changed since you last wrote gives the reader a reason to reply, where "just checking in" gives them none. Two or three of those, spaced out, is normal and expected.
