Case Study: ScaleX.ai achieves 7X higher prospect connect rates with SalesIntel Mobile Numbers

Revealed! SDRs are 7X More Likely to Reach Prospects Using SalesIntel Work Mobile Numbers

ScaleX.ai faced falling connection rates for B2B outreach as many prospects shifted to working from home; calling office switchboards and direct desk lines was proving ineffective. To test a better approach, ScaleX.ai used SalesIntel.io data to run a controlled experiment dialing 100+ VP- and C-level targets via switchboard, direct dial and mobile numbers to compare dial-to-connect effectiveness.

The experiment showed mobile numbers sourced from SalesIntel delivered far higher contact rates — a 10:1 dial-to-connect ratio for mobile versus 59:1 for switchboards and 73:1 for direct dials — making mobile outreach roughly 5–7X more effective. By using SalesIntel’s mobile data (48M+ numbers), ScaleX.ai gained materially more conversations, improving SDR productivity and reducing wasted dials with clear potential to increase pipeline and revenue.
