The shortlist

|---|
Method: live-web scan on 2026-10-18; 12 people, one row each. Followers are third-party snapshots (Aug–Oct 2026 where dated; some undated), not X API data. “Mentions” counts distinct pages citing the person’s angel/early-stage AI investing — a sourcing-strength signal, not an investment-performance score. Six hosts supply all source URLs; no URL supports more than two rows. Follower-source links were cut from the table for space; they appear in bubble tooltips.
