Customer.io

What is Customer.io?

Customer.io is a customer engagement platform that helps product-led companies deliver personalized, data-driven communications across email, SMS, push notifications, and in-app messages. Founded in 2012, the company has grown to serve thousands of businesses while remaining remarkably capital-efficient — reaching approximately $100 million in annual revenue with only $9.4 million in total funding raised.

The platform enables marketing and product teams to build sophisticated automation workflows triggered by real-time customer behavior and first-party data. Customer.io's focus on data-driven personalization makes it a favorite among product-led growth companies.

Where will I work?

Customer.io is a fully remote, async-first company. While originally based in Portland, Oregon, the team is distributed globally with no physical office requirement. The company operates with collaboration hours across time zones and emphasizes async communication through documentation and thoughtful written updates. A $250/month remote work stipend helps cover home office costs, and coworking space reimbursement is available.

What is the Customer.io team like?

With approximately 420 employees, Customer.io has a thoughtful, values-driven culture built around empathy, transparency, responsibility, and what they call 'awkwardness' — celebrating the unique quirks that make each person special. The team brings together engineers, marketers, designers, and customer success professionals who are passionate about building great software.

Work-Life Balance

Customer.io offers unlimited PTO and actively encourages employees to take at least 20 vacation days per year on top of holidays and sick days. After 5 years, employees earn a 1-month paid sabbatical. The async-first operating model means you have genuine flexibility over when and how you work, without the pressure of being constantly online.
