CONDITIONAL

Strongly reviewed (4.8 G2 / 4.8 Clutch) outsourced SDR department, but multi-channel not email-first, expensive, and watch the $200-350 per-appointment fee some clients report on top of retainer.

Verdict

An established, well-reviewed outsourced SDR department (G2 4.8/104, Clutch 4.8/109) serving complex industries with email, LinkedIn and phone. Two things to price in: it is closer to an SDR-as-a-service than an email-first campaign shop, and at least one reviewer warns of an 'appointment setting fee' of $200-350 charged on top of the retainer, which can break the math in low-close-rate industries. Retainers run $4.1-10.5k/mo. Professional but expensive, with occasional complaints on data reporting and bandwidth.
