Custom monthly retainer for outsourced sales development, sold in tiered team-size packages by number of BDRs (Start = 1 BDR, Grow = 2 BDRs, Scale = 3 BDRs). The engagement appears to be a done-for-you outsourced SDR/BDR program rather than pay-per-lead or pay-per-appointment pricing.

Whistle Ltd

Model
Custom-quoted outsourced SDR / appointment-setting engagements. The evidence points to a monthly service model for fully managed outbound SDR programs, plus a flexible staffing-style "Hire SDRs" offer; Whistle itself says pricing varies by scope depending on whether you hire SDRs, run full-service outbound, or need RevOps support.
Typical range
$5,000-$10,000+ / month
