## What the story says

Pump uses Clay to codify its ICP and build enriched territory lists for new sales reps, personalize outbound messaging by cloud provider and hiring signals, and automate follow-up for meeting no-shows.

Summary written by usedby from the source page, in English. The figures are those of Clay and Pump, not ours.

> New reps went from 90 to just 14 days to reach full productivity using Clay-enriched target account lists. This allowed Pump to ramp the 30 sales reps needed to hit their quarter-over-quarter revenue targets.

- **25%**: “generating 25% more revenue per rep”
- **23-26%**: “a no-show recovery rate of 23-26%”
- **$25M**: “This allowed Pump to scale from $1M to $25M in 18-months using Clay as their GTM foundation.”
- **5%+**: “Signal-based campaigns achieved 5%+ reply rates versus sub-2% industry baselines.”

> I don't know if we would have been able to grow so quickly without Clay. It's the core of our GTM stack. It's amazing, and we're only just beginning.

> Stuart Lundberg, Head of Operations
