Customers love us
Preferred by product-led companies

After evaluating Customer.io and Braze head to head, we decided to go with Customer.io for the ease of integration, transactional messages, our mobile capabilities especially push notifications, and for the support we know we would get.

With the flexibility and interoperability of Customer.io we’ve been able to build some truly insane and elaborate onboarding flows. If a colleague asks me if Customer.io can do something cool, no matter what they ask my immediate answer is always, “Yes. Yes it can.” I love always having the answers!
