BIO
I'm a co-founder of Isengard Industries. We build counter-drone interceptors that allies manufacture locally at a fraction of prime cost. Before Isengard I served as an Australian Army Officer, then spent a decade in private equity and private credit. I ran Balmoral, a private credit fund, and have led diligence and structuring on defence-tech deals across Australia, Ukraine and the Gulf. I'm also completing a PhD on economic warfare and hybrid threats.
