Cross-channel marketing automation; $242M revenue 2024; $2B valuation; $342.9M total funding; 1,000+ enterprise customers including DoorDash and Priceline; founded by ex-Twitter engineers
Iterable is a cross-channel customer engagement and marketing automation platform founded in 2013 by Justin Zhu and Andrew Boni in San Francisco, California, and headquartered in San Francisco with additional offices in New York, London, and Denver. The company was founded by two ex-Twitter engineers who believed that the existing marketing automation tools — built for the email marketing era — were not architected to handle the volume, speed, and channel diversity required by modern consumer businesses. Iterable was designed from the ground up as a data-first platform capable of ingesting real-time behavioral events and triggering personalized communications across email, SMS, push notifications, in-app messaging, and direct mail without requiring engineering resources to build and maintain each workflow.\n\nIterable's platform is built around a workflow canvas for visual journey orchestration, a real-time data engine that processes user events and attributes to power segmentation and personalization, an experimentation framework for multivariate testing, and AI capabilities including Smart Ingest (data quality), Brand Affinity (engagement scoring), and Predictive Goals (conversion prediction). The company serves B2C growth teams at brands including Priceline, Cinemark, Jersey Mike's, and DoorDash that manage high-volume, lifecycle-driven communication programs. Iterable competes with Braze, Klaviyo, Sailthru, and Salesforce Marketing Cloud for the modern B2C marketing automation market.\n\nIterable reported $242 million in revenue for 2024 and holds a $2 billion valuation with $342.9 million in total funding from investors including Silver Lake, Viking Global, CRV, and Index Ventures. Its customer base exceeds 1,000 brands, and its platform's combination of real-time data processing, flexible workflow orchestration, and native AI capabilities has earned it a strong position in a market where data-driven personalization at scale is increasingly table stakes for consumer-facing companies. Iterable's growth trajectory reflects secular demand for marketing infrastructure that can operate across fragmented consumer attention channels.
