Cosign's founder tells a16z that ChatGPT and Gemini both gave poor answers on the best New York startups, and pitches a personal MCP letting Muse, Grok Bot and Instinct plug into its agent-native networking platform.

a16z's @droovg explains why ChatGPT and Gemini struggle to find the best startups to work for, and how Cosign is building the missing data layer: "One thing that LinkedIn will never do is introduce an MCP that allows you to have vast search access over the graph." "When I was in New York this summer, I wanted to start meeting people who I thought I might be able to work for one day." "So I Googled, who are the best startups in New York? Gemini gave me a pretty bad answer. I switched to ChatGPT, it also gave me a pretty bad answer. That whole data layer of information is kind of missing right now." "We have an iMessage agent. We also have a personal MCP that lets you connect your Muse, your Grok Bot, your Instinct to the platform, to make this truly the first agent-native professional networking platform." @cosign @a16z
