According to a16z, the 'human signal'—derived from professional reputation and activity—is a critical but underutilized asset in the Silicon Valley ecosystem. The company aims to unlock this data, which has historically been anonymous and decentralized, to create positive network effects for founders, investors, and employees. CoSign is presented as the vehicle to achieve this through more effective talent and idea discovery.
“It's the human signal. I think there's so much data that we've been able to extract from just professional activity, from the products that people launch, from the companies they found, from the investors that they've, you know, chosen to work with.”
“And it's all been so anonymous. It's been so decentralized. And I think there's just a massive opportunity to unlock all of that.”
“And to turn it into a positive network effect for the entire ecosystem.”
