What should you ask in the meeting?

What are red flags?

Build your list first with how to find the right investors, then plan outreach with cold emails that get replies.

What does a worked example look like?

Suppose you are building payroll software for small European companies and you find a partner at a seed fund through a newsletter. Twenty minutes of research shows:

Result: tailor the pitch around compliance as a moat, raise the portfolio overlap early and openly, and mention that you spoke with one of their founders.

What should you write down?

Keep a simple record for each investor in your pipeline: fit score, recent relevant deals, potential conflicts, partner interests, reference notes and the date of your last contact. Over a round, this becomes your most valuable document; over several rounds, it becomes your network.

How do you ask for a reference without making it awkward?

Be direct and brief: "We're talking with [partner] about our pre-seed. Would you have 10 minutes to tell me what working with them is like, especially when things were hard?" Most founders say yes. Ask the same three questions each time: how they help, how they behave in difficult moments, and how quickly they decide.

Frequently asked questions

Why should founders research investors?

To check fit, avoid conflicts, tailor the pitch and understand how the investor behaves after investing.

How do I check if a VC is still investing?

Look at their most recent investments and when their current fund was raised.

Should I ask investors for references?

Yes. Ask founders in their portfolio, including ones whose companies struggled.

Is it a red flag if an investor charges a fee to pitch?

Generally yes. Legitimate venture investors do not charge founders to pitch.
