Cosign bets on reputation as Silicon Valley’s next talent signal
The Reputation Graph of Silicon Valley | Introducing Cosign
As AI expands the volume of information and outreach, trusted context could determine which people, companies, and opportunities receive attention.
- 1Cosign treats selective endorsements as durable signals for hiring, investing, and finding overlooked talent.
- 2The platform aims to preserve career context and network memory beyond fleeting posts, follower counts, and conventional profiles.
- 3Its opportunity is not replacing LinkedIn or X, but organizing scattered reputation signals into a richer social CV.

The group uses early endorsements of Samuel Harris Altman and Eric to illustrate how publicly backing talent can create lasting network memory.
The brief
Erik Torenberg, Josh Elman, Olivia Moore, and David Booth introduce Cosign, a platform built around trusted endorsements of people, companies, and products.
The argument starts with a simple scarcity: conviction about people is valuable, but conventional profiles and noisy markets often hide who identified talent early.
Cosign would preserve mentorship, launches, career transitions, and overlooked contributions as searchable context rather than letting them vanish in social feeds.
The product is positioned alongside LinkedIn and X, not as a replacement: its proposed edge is a richer social CV built from differentiated relationships.
The episode’s sharpest claim is that positive reputation compounds: early believers can help others while becoming part of the network memory around emerging talent.
