Creator Overlap
Find out how much of their audience two creators share — before you book both of them.
Overview
When you work with multiple creators in a single campaign, you're assuming you're reaching different people. Often, you're not. Creator Overlap lets you measure the shared audience between any two creators so you can make smarter decisions about who to include in a campaign.
Why it matters
If Creator A and Creator B share 40% of their audience, booking both means roughly 40% of your budget on Creator B is reaching people who already saw your message from Creator A. That's not necessarily bad — frequency can help — but it should be a deliberate choice, not a surprise.
