Customer.io

Automated messaging platform for product-led companies

PaidFeaturedAdded Sep 1, 2012

About

Customer.io is a messaging automation platform that lets product and growth teams send targeted emails, push notifications, SMS, and in-app messages based on real-time user behavior. Unlike marketing-first tools, Customer.io is built around event-driven workflows — trigger messages when users complete actions, hit milestones, or show churn signals. It supports liquid templating, A/B testing, and a visual workflow builder. Particularly strong for SaaS onboarding sequences and product-led growth messaging.

Origin Story

By Colin Nederkoorn

The Problem

Marketing email tools send batch-and-blast campaigns. Product teams need behavior-triggered messaging tied to actual user events.

Building It

Founded 2012, bootstrapped to profitability. Trusted by thousands of SaaS companies for lifecycle messaging.

What It Means

Shows that messaging automation should be triggered by product events, not marketing calendars.

The Dream

Power every meaningful automated message between a product and its users.
