About Customer.io
Customer.io is a customer engagement platform that companies use to automate messaging across email, mobile push, in-app messages, SMS, WhatsApp and webhooks. Its Journeys product turns first-party behavioral data into triggered campaigns, and Data Pipelines is a customer data platform that collects events and syncs them between warehouses and other business tools. The platform is built for technical marketers who want to write their own segmentation logic, templating and email code, and it also sells Parcel, a standalone email code editor acquired in 2022. Customer.io makes money by selling monthly subscriptions that scale with the number of customer profiles in a workspace and the volume of messages sent, starting at $100 a month for self-serve Essentials plans and $1,000 a month for sales-assisted Premium plans. The company was bootstrapped for its first nine years and raised its first institutional round, a Series A from Spectrum Equity, in 2022.
