Stephen Cohen

Co-founder of Palantir Technologies
Tracked because Palantir co-founder; post-Palantir activities in defence/government sectors remain underdocumented
Editorial summary · AI-drafted from public records

Technical co-founder of Palantir Technologies who built core engineering and data integration capabilities. Post-Palantir professional activities are less publicly documented than Joe Lonsdale's, with career trajectory warranting deeper investigation for potential undisclosed advisory or technical roles in defence and government sectors.
