I sat down with Daniele Perito to talk about his new company @depthfirstlabs. He was previously on the founding team of Cash App and cofounder of Faire. We talked about the future of software security in the age of AI and what becomes possible for both attackers and defenders, what he learned from Cash App and Faire, and what's the same and different across these companies.
