Customers love us

Preferred by product-led companies

Customer.io is this incredibly flexible tool that allows you to do all these amazing email campaigns, and Attio is the equivalent that allows you to do all these amazing things with your CRM. That’s super important when you’re an early-stage startup: you don’t waste time, you don’t waste money, and everyone on your team can do anything.

Alex Vale

Manager

Messaging frequency is key for our strategy. We can’t email our customers daily, so increasing frequency with a multi-channel strategy is how we can scale message volume. The conversion rates prove that strategy is working.

Ugo Iwuchukwu

Head of Marketing

We send every single customer profile from our database into Customer.io. Attributes are constantly changing too, so we need a platform that automatically updates people's values whenever they change.
