Tracks revenue down to the individual message and customer touchpoint.
Why it works
Data Integration: Syncs 100% of historical and real-time data from e-commerce stores instantly.

Founder story
Founded in 2012 by Andrew Bialecki and Ed Hallen in Boston. Andrew, a software engineer, realized that the biggest problem for online businesses wasn't just sending emails, but using the data they already had to make those emails useful. They bootstrapped for several years, focusing on the product, before scaling into the industry leader for D2C marketing.
