Built by advertisers, for advertisers.

We've sat in your seat. We know the daily grind of paid budgets quietly bleeding to people who already converted. WasteNot is the tool we wished existed.

The thesis

Modern ad platforms optimize for the click that's easiest to win — and the easiest click is almost always your existing customer. That math is great for the platform; it's a slow leak for the brand. Suppress your existing buyers and the platform suddenly has to go find new ones for you.

Every dollar spent reaching a customer who already bought is a dollar that could have gone to acquisition. WasteNot exists so your budget reflects that.

What we believe

  • Marketing should own marketing. Growth teams shouldn't need to file a data ticket every time a campaign rule needs to change.
  • Data quality is the product. Match rates, refresh cadence, and edge cases are what separates a working exclusion from a decorative one.
  • Pay for outcomes, not seats. Pricing scales with your platform spend, so the program pays for itself before you ever expand it.
