CoSign plans to feature three core types of endorsements on user profiles: 'who shaped your career' (mentor), 'would work with anywhere' (collaborator), and 'person to watch' (future potential). These categories aim to provide more granular and meaningful signals than simple follower counts, reflecting deeper professional relationships and insights. The platform also intends to allow endorsements for companies.
“One is who shaped your career.”
“Two is, would work with anywhere or in the trenches with.”
“And then third is person to watch.”
