a16z introduces Cosign, turning endorsements into durable professional signals to help discover talent before the market does.
a16z’s Erik Torenberg, Josh Elman, Olivia Moore, and David Booth introduce Cosign, a professional-reputation product intended to make trusted recommendations easier to find than credentials or generic LinkedIn connections. Profiles can identify mentors, people you would work with anywhere, and emerging talent to watch; users can also signal interest in hiring, funding, or meeting someone. The panel describes a living directory of people and companies, where public endorsements and private signals can help match opportunities when timing is right. They contrast Cosign’s granular relationship context with LinkedIn’s broad connections and X’s fleeting posts, and discuss preserving positive feedback, including recognition for behind-the-scenes contributors. Moore cites receiving 2,000 responses to a startup hiring form as AI increases noise and makes human conviction more valuable. The guests frame Cosign as a community-built tool for surfacing overlooked talent, with early believers often remembered for helping careers take off.
