Thesis

Mark VC takes a deeply founder-centric approach, building '360-degree behavioral maps' of founders through extensive personal reference calls. They invest across industries but focus on security & defense, healthcare, consumer, and enterprise software. They strive to be the most valuable investor on the cap table through hands-on coaching and operational support.
