How to find investors for your startup

Find investors for your startup through the people who already have their attention: founders they have backed, angels and operators in your space, your accelerator, and investors who just committed to you. Fill the gaps with investor databases, small events and short cold emails. Then check every name for stage, check size, sector, recent activity and whether they lead, before you spend a meeting on it.

Sourcing and qualifying are two jobs. This post covers both. Turning the names that survive into a tiered, tracked list is a third job, covered in how to build an investor pipeline from scratch.

Where do early-stage investors actually come from?

Roughly in order of how well each source tends to convert into a real conversation:

1. Founders an investor has already backed. Look up the portfolio, find a founder a year or two ahead of you, and ask for advice before you ask for an intro. Portfolio founders are far easier to reach than partners, and their word carries.
2. Investors who just committed. The moment someone says yes, ask who else they would want around the table. A fresh commitment is the most credible introduction you will ever have.
3. Angels and operators in your category. Former founders and senior people at companies your buyers already know. They tend to decide faster than funds, and they usually know which seed funds should come next.
4. Accelerators and their alumni. The demo day and the program's investor network are the obvious value. The underrated one is last year's cohort, who can tell you which funds actually led their rounds and which only followed.
5. Investor databases and lists. The fastest way to go wide. Filter by stage, sector and geography and you have a long list in an afternoon. The ceiling is the quality of the data, which we come back to below.
6. Events and communities. Small, sector-specific events beat big conference floors. The goal is a second conversation, not a pitch by the coffee station.
7. Syndicates and AngelList. A syndicate lead pools capital from their backers into one check, so one lead who likes you can bring a group. Useful for filling a round, less often for leading one.
8. Cold outreach. It works more often than its reputation suggests, but only when it is short, specific and aimed at someone who has backed something like you.

How much do warm introductions really matter?

A lot, and it is better to plan around that than to resent it. Paul Graham's essay How to Raise Money ranks introductions plainly: "The best type of intro is from a well-known investor who has just invested in you." Next: "The next best type of intro is from a founder of a company they've funded."

The useful reading is not "know the right people". It is that the introducer's credibility transfers to you. A founder who used the investor's money well is a strong introducer. A friend who once met the partner at a wedding is not, and a lukewarm intro can do more harm than a good cold email.

Make every intro easy to give. Send your introducer a three-sentence blurb they can forward unedited: what you do, the one number that matters, and why this specific investor. If they have to write it themselves, the intro waits.

Does cold outreach to investors work?

Sometimes, and the ones that work look alike. YC's summary of Michael Seibel's advice on cold emailing investors starts with length: "Make it short, i.e. 60 seconds or less to read." It also says to explain clearly what the company does, and: "Don't immediately request an in-person meeting." The same summary warns against sending multiple follow-ups quickly.

Cold works best on investors whose public activity already points at you: a partner who has written about your category, an angel who just backed a company adjacent to yours, a fund that announced a new vehicle with your sector in the thesis. Name that reason in the first line. It is the only part of a cold email that proves you did not send it to two hundred people.

If you plan to talk about the raise publicly, on social media or at a demo day, ask your lawyer first. How a private round is advertised has securities-law consequences.

How do you check that an investor fits?

Before a name earns a meeting, it should pass six checks:

• Stage. Do they write first checks at your stage, or mostly follow on from their own earlier investments?
• Check size. Does their typical check make sense against your round? An angel and a fund that needs meaningful ownership are different conversations.
• Sector. What have they actually funded, as opposed to the sector list on their website?
• Recent activity. Have they made a new investment at your stage recently? Funds go quiet when they are between funds or holding money back for follow-ons.
• Lead or follow. Do they set terms and take a board seat, or join rounds someone else leads? A round of ten followers and no lead does not close.
• Conflicts. Have they backed a direct competitor? Many will not back two companies chasing the same customer.

The evidence lives in recent funding announcements, the investor's own posts, and founders in their portfolio, who will usually tell you in one message whether the fund led, followed or simply took the meeting.

How good is investor database data?

Good for breadth, weaker on the details that decide fit. Every database is a snapshot. Partners move firms, funds finish deploying, stated check sizes drift away from the checks actually written, and the newest angels are underrepresented because nothing public says they invest yet.

Use a database to build the long list fast and to filter out obvious misfits. Then verify the top of the list by hand against the six checks above. That applies to ours as much as anyone's: no database knows that a partner stopped doing seed deals last month, but a founder in their portfolio might.

Where does Boxsy help with finding investors?

Boxsy's investor database covers more than 150,000 VCs, angels and accelerators. You can search and filter it, shortlist names, and bulk-add them to your investor pipeline in one click. Boxsy also offers AI-recommended matches based on your pitch deck, data room and connected email and calendar, and enriches investors already in your pipeline against the database. Search is available on the plans that include the investor database, so check which plan fits your raise or start a free trial and see the pipeline build from the conversations you have already had.

Source wide, then qualify hard

Finding investors is not a networking talent. It is a habit of asking the right introducers, going wide on the long list, and refusing to let a name into your round until it has passed the checks. The founders who run out of investors are rarely the ones with small networks. They are the ones who never qualified the list they had.

If you would rather source and qualify the first list with someone, Boxsy Ready sets up your pipeline, data room and outreach in a four-week program. Or talk to our team about the round you are planning.
