Most family-office lists are a directory of wealth, not of people who write startup checks. A family office that only does real estate or late-stage PE will never reply to a pre-seed deck.

Before you send:

1. Do they write first checks into startups, or only follow-on / buyouts?

Angels write their own first check. VCs have a process, a partner meeting, and a stage they already decided. Sending a seed deck to an angel, or a pre-seed deck to a Series A fund, is how you get silence.

Before anyone gets the deck:

1. Last check: did they write a first check in the last year, or only lead later rounds?

Angels do not read 20 slides. They skim: what you do, why now, why you, and whether they even write this check.

A pre-seed deck that gets read has:

1. Problem in one sentence a stranger can repeat

2. A product screenshot, not a metaphor

3. Why this founder

4. Amount, use of funds, check size you want

5. Proof you can sell: revenue, waitlist, or 10 real conversations

Most "investor lists" are a scrape: a public directory plus whoever you follow, 400 rows, almost no replies. The work is not collecting names. It is matching: who writes a first check, in your sector, at your stage, in the last year.

What I do instead of growing the sheet:

1. Start from recent first-checks in your sector, not logos

2. Drop anyone who has not written a pre-seed or angel check in 12 months

Most pre-seed lists I see are a scrape: a public directory plus a Twitter follow list, 400 names, almost no replies.

The list is not the work. Matching is. Stage, check size, whether they wrote a first check in the last 12 months, and whether they even do your sector.
