His investment thesis targets pre-seed through Series A stages, focusing on sectors including AI infrastructure, enterprise security, robotics, biotechnology, and SaaS[9][11].

Mahaffey’s distinctive point of view centers on backing “durable companies” built by technically strong founders, a philosophy reflected in SNR’s name, which stands for signal-to-noise ratio[4][10].
