Method: repaired 2026 startup-scouting dataset, 28 announcement rows (one per candidate), sources published 2026-01-20 to 2026-08-26; research current through 2026-08-27. Funding, lead investors and stealth-exit timing are read from each source headline or announcement text where the structured field was blank; blank founder, investor, client and website cells are unresolved, not negative findings. Sector tags (physical AI / infrastructure / other) are derived from words in each row's own description or headline; no validated sector totals were supplied, so none are shown. No source stated a live X/Twitter follower count — the low-Twitter column is unverified for every row. Founder, investor and client detail was cut for space where the source text was unreliable; follow each source link for the full announcement.
