Diligencing your investors

In this lesson

why you should run diligence on the investors who want in, what actually matters when choosing them, and a simple framework for prioritizing.

Why this matters

When a VC wants to invest, it's easy to feel flattered and just say yes. But you may work with these people for a decade or more, and a bad investor is far harder to remove than to avoid in the first place. So diligence them the way they diligence you.

Backchannel before you accept

The most thoughtful founders quietly talk to a couple of founders a VC has already backed, ideally ones who aren't on the VC's own reference list. Ask what the investor is actually like when things go wrong, not just when they're going well. Do they add real value, or do they create stress? The portfolio companies on a fund's website are an easy place to start.

Judge them as long-term partners

You'll live with these people through some of the hardest years of your life. Ask yourself honestly:

Do they stress you out?
Do they push bad ideas hard?
Do you actually like how they interact with you?

Don't assume any of this improves after they invest. If anything, it can get worse as they gain power, for example through a board seat.

Be realistic about "value-add"

Most VCs are less useful than their pitch suggests. Their offers tend to cluster around recruiting help and company-building advice, both of which you can often get elsewhere from experienced operators and advisors. So don't agonize over which investor will help the most. Weight more toward who you want in the room and whose judgment you trust.

That said, some investors are genuinely valuable: deeply technical ones who are experts in your field, or true top-tier operator-advisors who understand how to build a company. When a fund claims a specific kind of help, verify it with their portfolio founders rather than taking it on faith.

A framework for prioritizing

First, fill your round with people who aren't jerks.
Then prioritize the people you genuinely want to work with.
Only once you have excess interest, get selective on value-add: technical guidance, hiring, go-to-market, customer intros, or connections to later-stage investors. Rank funds by the value they claim, then verify it.
Throughout, use tranching to reward the ones who move fastest.

Key takeaways

Diligence investors as hard as they diligence you. You may work together for a decade.
Backchannel with their portfolio founders, especially ones not on the official list.
Optimize first for non-jerks and people you trust, then for verified value-add.
Don't overrate generic "value-add." The real value is deep technical or top-tier operator help.
