cryptopolitan.comMethod: live-web scan of results published Oct. 23–29, 2026 (as of Oct. 29), keeping only rounds reporting explicitly characterized as seed — not pre-seed, Series A+, historical totals or valuations — by companies building a substantive AI/ML product or enabling technology. 23 unique startups across 17 source hosts; a duplicate Northstar row was merged into Northstar Security AI Inc. and Rendezvous Robotics was omitted (autonomous spacecraft, no substantive AI/ML product established). Amounts are as announced, unconverted; dates are public announcement dates, not closing dates; some announcements have a single located source. The scan is broad but not a guaranteed exhaustive universe. Sector descriptions shortened for space; full detail available via each source link.
