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?
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.
