Investment thesis

Phase Alpha backs disruptive technology aimed at redefining national security, focusing on six priority critical-technology areas. The firm is staffed by innovators, operators and investors with deep national security experience who scout, analyse, invest in and help grow companies serving this opaque but critical market. It emphasises sovereign Australian defence and national security capability, aiming to put technology into the hands of end users sooner, and expresses a strong preference for backing veteran founders.
