a16z launches Cosign, a product to make Silicon Valley reputation graph legible
a16z Podcast · rss · 2026-09-25
- a16z's Erik Torenberg talks with Josh Elman, Olivia Moore, and David Booth about Cosign, a new product built on professional reputation: endorsements of people, companies, and products you'd vouch for.
- Core idea: the most valuable career signals in Silicon Valley aren't credentials but who believes in you — mentors, collaborators, up-and-coming builders.
- The episode explores why human endorsements may grow more valuable as AI floods outreach channels, what LinkedIn-style networks miss, and how legible reputation can surface talent earlier.
