Promising
One audience is meaningfully larger. Lead your pitch with what you add beyond reach.
Directional estimates based on public campaign benchmarks — a ~15% audience overlap discount, format-specific reach and CPM ranges, and the ~36% engagement lift partnership campaigns see over solo campaigns. Not a guarantee of results.
How the estimate works
Reach starts with both audiences combined, then discounts roughly 15% because some people already follow both brands. That number is multiplied by how much of an audience each campaign format realistically reaches — a co-branded product drop travels furthest, a newsletter swap travels least but lands with the highest intent.
Engagements apply a format-specific engagement rate to that reach, with the ~36% lift partnership campaigns see over solo campaigns already baked in.
Media value prices the reach at the CPM you'd pay to buy it — $14 to $26 per thousand depending on format. It's the number to put in front of a finance team.
Opportunity score blends audience parity with combined scale. Two similarly sized brands score highest, because both sides gain comparable exposure and the deal is easier to close.
