The Trellner Review

Startups get disqualified by agency qualification gates more often than by price. We collected every stage, revenue and deal-size requirement that eleven GTM engineering agencies print on their own sites, read October 11, 2026.

  • Gated: ColdIQ (past product-market fit, high-value sale), Understory (post-PMF, some GTM motion, two-quarter commitment), Growth Engine X ($1M+ revenue, 100,000+ contact market, $5,000+ lifetime gross profit per customer), DevCommX (defined ICP, $5K+ ACV, sales team ready to close), The GTM Engineering Company (seed to Series B, needs a CRM)
  • No stated requirement: Sales.co, SalesCaptain, RevPartners, demandDrive, The Kiln, Earleads

On the gate-free pages, the check moves to the commitment. Sales.co's page states $5,500 a month flat, no setup fee, month to month, plus its own reply record: 0.84% of 336,257 sent contacts replied in person, and 42 of its 143 bookings came from contacts who never replied at all.
