Iterable is a marketing automation platform that enables brands to deliver personalized communications across email, SMS, push notifications, and other channels. The platform's segmentation and automation capabilities help more than 300 leading brands drive customer engagement at scale.

645 Ventures met Iterable's founders in 2014 and invested in the seed round, making it the fund's first investment. Our belief in the founders' early product vision prompted investment at a stage when the company had only 5 people, 6 customers, and a few hundred thousand dollars in revenues. The founders identified an opportunity to deliver predictive analytics, real-time A/B testing, and advanced cohort analysis to SMBs seeking better marketing automation. Early diligence revealed strong customer traction and the company's ability to convert customers away from larger, less innovative incumbents (such as Constant Contact, SailThru, and MailChimp), further justifying Iterable's disruptive potential.
