Pronto is a powerful tool for finding key profiles much more efficiently than Clay's Find People. A must-have solution for outbound agency.
Sylvain NguyenCEO, FormulaNow
Pronto is insanely good. The quality of the numbers is just on another level. Compared to Lusha, it's day and night.

01We're a small sales team. Is Pronto worth it?
If you have at least one SDR and a defined ICP, Pronto saves them 3–5 hours a week and fills their pipeline with verified, ready-to-call contacts. Day one.
02We already use Apollo or Lusha. Why switch?
You're not switching, you're upgrading. Apollo and Lusha give you one data source. Pronto gives you 100+, with waterfall enrichment that finds the contacts they miss. That's about 30% of your market.
03How does Pronto compare to Clay?
Clay is a canvas: you build the workflow. Pronto is an engine: it ships with the workflow. If you love tinkering, use Clay. If you want verified pipeline in your sequences every morning, use Pronto.
04How long does setup take?
Under 30 minutes. Connect your CRM, define your ICP, and your first list is ready before your next standup.
05Do we pay for bad data?
Never. You only pay for verified, valid contacts. If the email bounces or the phone is wrong, you don't pay. Simple.
06Is Pronto GDPR compliant?
Yes. GDPR-compliant by default. Data processed in EU regions, DPAs on request, and every contact sourced from GDPR-legitimate providers.
