Frequently asked questions

How many Sustainability investors are on RaiseHunt?

RaiseHunt currently lists 4,594 Sustainability investors.

Are Sustainability investors angels or funds?

Both. 270 are angel investors putting in their own money, and 4,324 are people making investment decisions at 1,552 firms.

Where are most Sustainability investors based?

The largest concentrations are in London, New York and Paris.

What stage do Sustainability investors invest at?

Most list Seed and Late-Stage among the rounds they take part in.

How do I contact Sustainability 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 Sustainability 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 Sustainability investors only back Sustainability 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.

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.

What if no Sustainability investor replies?

Usually the list was too short or too loosely matched, not that the company is unfundable. Widen it, tighten who you are writing to, and rewrite the first two lines of the message. Those lines decide whether anything below them gets read.

What is the difference between an angel investor and a VC fund?

An angel invests their own money and can decide alone, which usually makes the process shorter. A fund invests money it raised from other people, so it answers to those backers and normally runs a longer diligence process before it commits. Founders often raise from angels first and bring in a fund once there is more to show.
