Ehsan's Verdict

The Kustomer vs ZoomInfo debate misses a critical nuance. Kustomer was built for customer support-first teams and it shows in the API design and workflow assumptions. ZoomInfo approaches sales from first principles with a cleaner mental model. For 2026, pick Kustomer if you have existing infrastructure, ZoomInfo if building greenfield.
