In 2013, Andrew Boni, who worked at Google on AdSense, teamed up with former Twitter engineer Justin Zhu to found Iterable, a platform that lets marketing managers send messages to potential customers. As its name implies, the philosophy behind Iterable is that you’re given a platform to iterate, to try out many different approaches across a range of channels, leveraging data to build customer relations and engagement. From Iterable’s dashboard, salespeople can orchestrate welcome campaigns and trials, targeted sales, promotions, and product updates across mail, mobile push, SMS, in-app, web push, and direct mail channels.

Iterable also offers a feature called sent time optimization (STO), an AI-powered sending tool that automatically determines the time to send an email for engagement based on a user’s historical behavior. Over 300 customers have used STO to send more than 2 billion messages from more than 100,000 campaigns.

To date the company has attracted over 800 clients, including DoorDash, Fender, Calm, Box, and In June 2021, Iterable announced the close of a $200 million Series E that values the company at $2 billion post-money. The funds will be spent on hiring, marketing, and R&D initiatives, with an eye towards geographic expansion.

Corporate Responsibility

Charitable Causes

Iterable’s Chariterable Volunteer Program brings the company’s core values of trust and balance into fruition through employee growth and community development. The program truly shines during annual volunteer weeks, in which Iterators participate in local community charity initiatives such as GLIDE, SF Recreation and Parks, the Denver Rescue Mission, and Muttville, a senior dog charity. Though the Chariterable Volunteer Program has only been around for a few years, each quarter has seen around $4,000 donated by Iterators — with Iterable matching that 1x for a total $8,000 in contributions.

Diversity & Inclusion

The Iterable recruitment team has used Textio for all job postings in an effort to prioritize language that is gender-balanced and entirely inclusive. Applicants are sourced from workforce diversity groups such as Techqueria, a tech industry collective which supports Latinx professionals and promotes unique hiring opportunities.

The affinity groups within the Iterable team are Women’s Network, Black at It, Remote Employees, Mixed Identities, Zenit, and Pride for LGBTQIA+ individuals.

In-person events in past years have encouraged the celebration of diversity. The company marked the Lunar New Year with a Chinese banquet, held a Women in Leadership Q&A panel for Women’s History Month, and sponsored a staff trip to the Museum of the African Diaspora in honor of Black History Month.
