About Customer.io
Customer.io is a marketing automation and messaging platform founded in 2012 by Colin Nederkoorn and John Allison, headquartered in Portland, Oregon. The company operates as a remote-first organization and provides tools for product and marketing teams to build automated messaging workflows across email, SMS, push notifications, and in-app channels.
The platform centers on behavioral data, allowing teams to trigger and personalize messages based on real-time user actions and attributes. Customer.io serves software-as-a-service companies, mobile app developers, and e-commerce businesses that require granular segmentation and event-driven messaging. Its product suite includes a visual workflow builder, a data pipeline product called Journeys, and a CDP-adjacent data layer for managing customer profiles.
Customer.io raised a Series A round of $35 million led by Silversmith Capital Partners in 2022, its first institutional funding after operating for roughly a decade without outside investment. The company has remained largely bootstrapped through most of its history, which it has cited as a factor in its product development pace and business model. As of the early 2020s, the company employed several hundred people across a distributed workforce.
