Incrementality Measurement Platform
Looking for an incrementality measurement platform aimed at Amazon × Meta? Spillmark runs geo holdout tests and reports caused sales with a range.
- One clear geo holdout path
- Locked designs and append-only results
- Profit after fees included

What you get
Spillmark is software for Amazon brands that run Meta ads. It runs one clear geo holdout with published monthly pricing.
You give up a broad multi-channel enterprise package. You get a focused holdout, a locked ledger and prices on the site.
Honest about scope
Spillmark centers on geo holdouts and profit. MMM remains a separate category. Enterprise geo suites still make sense for multi-channel global brands.
When Spillmark fits
Smaller Amazon brands that want a holdout they can approve and afford. Not a claim that Spillmark matches every Measured feature.
