Case Study: Customer.io grows sales-qualified leads 70% with Apollo.io
Key results
The challenge
Customer.io's sales team relied on Close CRM and ZoomInfo, which required manual data entry for every touchpoint and lacked scalable sequence automation. That limited how quickly the team could build and run repeatable outbound playbooks.
The solution
Customer.io consolidated prospecting, enrichment, and multi-channel engagement onto Apollo.io. The team built scalable playbooks aligned to its ideal customer profile and used Apollo's sequencing to automate outreach for the first time.
“Apollo is two platforms in one...it's saved us clicks, saved us time, and allowed us to create sequences for the first time.”

The results, in context
With Apollo, Customer.io reported a 70% increase in sales-qualified leads. Over the same period the sales team grew from 12 to 29 salespeople while maintaining quota attainment across the expanded team.
