→ WHAT IT COVERS A16z's David Booth and Dhruv Gupta discuss Cosign, a professional networking platform built around trusted endorsements rather than cold outreach. They cover the newly launched Cosign Awards, which spans 135+ rising stars and 76+ podcaster nominees, and explore how AI agents could automate first-pass professional matching. → KEY INSIGHTS - **Reputation-Based Hiring:** Cosign structures professional discovery around explicit endorsements — one person vouching for another — rather than resume screening or cold applications. With 50,000+ profiles already on the platform, users can browse relationship graphs, trace career trajectories, and identify candidates through trusted referrals, replicating the informal vouching that drives most consequential career moves at scale. - **Curated Lists as Talent Intelligence:** Cosign's list layer allows investors, operators, and writers to publish curated company and people collections. Packy McCormack's Not Boring list, for example, surfaces 36 vetted companies for job seekers. Browsing cosign.co/lists gives access to hundreds of such lists, including Thiel Fellows and Interact Fellows, enabling cross-referencing of talent pools that no single database currently aggregates. - **Agent-to-Agent Professional Matching:** Cosign is building toward a model where personal AI agents negotiate compatibility before humans connect. Rather than cold emails landing in identical inboxes, an agent representing a job seeker could conduct a first-pass conversation with a company's agent, identifying shared goals and complementary skills before escalating to a human hiring manager — eliminating noise from both sides. - **Surface Area for Luck:** David Booth frames Cosign's core value as expanding a user's probabilistic exposure to career-changing encounters. Building out a Cosign profile, engaging with the agent via iMessage or MCP integrations with tools like Grok and Claude, and participating in awards nominations all increase the likelihood that a future co-founder, employer, or collaborator discovers you through the platform's relationship graph. - **MCP Access Unlocks Hidden Startup Talent Data:** Cosign offers a personal MCP that connects to external AI tools, enabling structured search across its graph — something LinkedIn explicitly does not provide. Dhruv Gupta notes that queries like "best biotech startups in New York" return poor results from Gemini and ChatGPT because that data layer is missing; Cosign aims to become the structured source answering those questions with personalized, graph-informed responses. → NOTABLE MOMENT Gupta recounts how his entire entry into the San Francisco tech ecosystem came from a single person — MTS CEO Brent — recognizing his work at Polymarket and taking a chance on him. Without that one endorsement, his career path into tech would not have existed. 💼 SPONSORS None detected 🏷️ Professional Networking, AI Agents, Talent Discovery, Startup Ecosystem, Reputation Economy
