About Coretas

\n

Coretas is an AI platform for advertising teams that sits above the ad platforms. It brings cross-platform data into one dashboard, surfaces opportunities, builds media plans in seconds, and creates campaigns that marketers approve before anything goes live. Ecommerce brands and the agencies that work with them use Coretas to spend less time on manual work and more time on decisions that grow revenue. We're building a small team of practitioners who know ecommerce marketing from the inside.
