Greylock general partner Mike Duboe talks with Treat CEO Matt Osman, Fermat CEO Rishabh Jain, and independent analyst, consultant and investor Eric Seufert about the changing world of commerce performance marketing following the passage of ATT.

But the passage of Apple's App Tracking Transparency policy in 2021 turned that world on its head. Now, companies have gotten creative about the ways they reach their audience, which has given rise to a class of startups like Treat and Fermat that provide the tooling and platform to develop, test, and iterate marketing campaigns.
