Stephen DiBartolomeo is a former Navy cryptologist turned venture capital investor at Scout Ventures who specializes in semiconductor supply-chain security and detection of counterfeit microelectronics, making him a highly domain-specific investor rather than a generalist defense tech investor. He actively operates on both sides of the table as a principal investor and as co-founder/president of Chiplytics, a hardware security startup he helped incubate within Scout itself, giving him current hands-on founder experience while investing in similar deep tech domains.
