Customer.io

We founded Customer.io in 2012 to build a customer engagement platform. Our AI-powered platform helps organizations create personalized customer journeys across email, in-app messages, SMS, push notifications, mobile, and web. We use first-party data to manage and personalize customer messages, integrate with other tools, and move real-time data to build campaigns based on unlimited profile attributes, events, or actions.

Our products include Journeys, a messaging automation tool with a visual workflow builder, omnichannel support, Design Studio, analytics, conversion goals, and A/B and cohort testing. Data Pipelines is our customer data platform, providing APIs, webhooks, event triggers, Reverse ETL for data warehouses like Snowflake and Big Query, ad audience synchronization for platforms such as Google, Facebook, Instagram, and YouTube, and support for custom objects and unlimited data sources and destinations. Parcel is our code editor for email.

Over 7,400 brands use Customer.io. In 2024, our platform processed more than 56 billion messages, 7.3 billion webhooks, and 5 billion daily API calls for 78,000 active users. We are ISO 27001 certified and compliant with GDPR, HIPAA, SOC 2 Type II, and CCPA standards, with secure data residency options in the EU or US.

Our mission is to give customers a unified view of their audience and a single platform where unlimited, real-time data drives more effective engagement.

Our core values are Empathy, Transparency, Responsibility, and Awkwardness. These values, along with our leadership principles, guide how we work together and apply to every role within our company.

We are a fully remote-first company with a global team of 201 to 500 employees. Our work environment values flexibility and collaboration, and we cultivate a culture that welcomes diverse perspectives and expertise.

We use an async operating model to encourage thoughtful communication and reduce unnecessary meetings. We also set collaboration hours across different time zones to support efficient teamwork. While we value digital flexibility, we also encourage in-person connections through collaborative work sessions, co-working spaces, and social events.

Our culture programs include casual gatherings for learning and connection, recognition and rewards, volunteering opportunities, our Ami Ambassador program, and both in-person and virtual team meetups. We are committed to Diversity, Equity, Inclusion, and Belonging (DEIB), working to create a supportive workplace where all employees can be their authentic selves. Initiatives like our Ami Resource Groups (ARGs) help us build community and celebrate diverse perspectives.
