Callbox has been in the lead gen game for over 20 years, with a big offshore team and multi-channel reach. Depending on how you want to operate, Lead Engine may fit better.
Callbox is one of the oldest names in B2B lead gen , 700+ employees, offices across APAC, and a proven multi-touch model. That scale comes with tradeoffs: less flexibility, longer contracts, and less direct access to the people doing the work.
Callbox runs a large offshore team model with account manager coordination, long-term retainer contracts, and standardized playbooks. Best for enterprises comfortable with process-heavy delivery.
Lead Engine runs a small, senior US-based team per account with month-to-month flexibility after month 3 and pricing published on the site. Better fit for growth-stage B2B teams.

Yes , every strategist, copywriter, and caller on your account is US-based. Callbox runs its SDR work primarily offshore (Philippines, Malaysia).
Our sweet spot is US and Canada with some UK/EU coverage. For APAC-focused outbound, Callbox has stronger regional infrastructure.
3-month initial commitment (that's how long outbound takes to prove itself), then month-to-month. Callbox typically requires 6 to 12 month contracts.
