What was breaking
Warp runs a phone-first outbound motion, and pickup rates are everything. Their existing data providers were returning phone numbers that rang out, hit voicemail, or were simply wrong — dragging pickup rates down to 8%.
The team was already running a data waterfall across multiple providers, but none of them delivered consistently accurate phone data. Every missed connection was a wasted dial and lost pipeline.
“When you're dialing 200+ numbers a day, the difference between 8% and 13% pickup is massive. That's dozens of extra conversations every week.”
Hayk Ghon, GTM Lead
What they changed
Warp added Cleanlist as a data source in their enrichment waterfall. Cleanlist's phone data — sourced and verified across 25+ providers — filled the gaps that their existing tools couldn't cover.
By layering Cleanlist into their existing workflow, Warp got the highest accuracy phone numbers without rebuilding their process. The data quality improvement was immediate.

Cleanlist data became the highest-accuracy source in Warp's entire waterfall. The team now prioritizes Cleanlist-verified numbers, knowing they deliver the best connection rates across their stack.
