Post counts are the public LinkedIn posts Imagine AI collects for this person, taken over the 90 days to Oct 20, 2026; reshares are left out of the post count and the format mix. Follower counts come from the last profile check. The band compares a typical post, the geometric mean of reactions on posts that have had two weeks to settle, with the Imagine AI research baseline of 20,000+ posts from B2B startups. How the benchmark is built.
