Three creators in one niche share ~38% of their audience

Three creators in one niche share ~38% of their audience

Measured follower overlap within a single vertical roster.

— Any 2 niche creators ~24% ████████
— Any 3 niche creators ~38% █████████████
— Any 5 niche creators ~51% ████████████████

Unique reach grows far slower than gross reach as you stack same-niche creators, so the fifth booking buys mostly repeat impressions. The duplication tax is invisible unless you dedupe.

So what: cap same-niche rosters at 3-4, then cross into adjacent verticals for net-new reach.
