Luke Armour built Chaac Ventures as a highly focused, alumni-centric VC fund around the Princeton ecosystem, positioning himself as a first call partner for Princeton founders and deliberately filling a gap he observed versus Stanford, Harvard, and MIT-style alumni funds. He started the fund in his mid-20s as a first-time GP and actively positions Chaac as the connective tissue of the Princeton tech community, expressing conviction that Princeton founders tend to pursue overly-ambitious ideas in frontier areas like AI and cybersecurity that create a differentiated risk/return profile.
