John Chang and the case of the missing key
A chip can be copied. Its smallest manufacturing differences are another matter. John Chang is building Jmem Tek around that distinction, taking research from Taiwan into the business of trust.
Dave Krauthamer and the art of changing the locks
After building a business that moved companies into the cloud, Dave Krauthamer turned to the encryption holding their networks together. His next problem: how to change the locks while everyone is still inside.
Kostas Chalkias and the Art of Trusting a Machine
An Amstrad in a Greek village led Kostas Chalkias toward the mathematics of trust. Now the Mysten Labs co-founder is asking what cryptography must protect when software starts acting on our behalf.
Vivek Nair
Vivek Nair is the co-founder and CEO of Multifactor (YC F25), an applied cryptography company building zero-trust authentication, authorization, and auditing for AI agents. He earned his Ph.D. in Computer Science from UC Berkeley at 22 as a Hertz Fellow, published landmark work on privacy in virtual reality, and served as a technical lead in cyber units at the Department of Defense and CIA before starting the company.
Rebecca Krauthamer
Rebecca Krauthamer is the co-founder and CEO of QuSecure, a San Mateo company building software that lets governments and banks swap out their encryption before quantum computers learn to break it. A Stanford Symbolic Systems graduate who jumped from AI to quantum in 2017, she turned a U.S. Air Force grant into a Series A-funded leader in post-quantum cryptography, counting the U.S. Army, Air Force, and Banco Sabadell among its users. A Forbes 30 Under 30 honoree and World Economic Forum council member, she argues cybersecurity is a mission for humanity, not just a product category.
