The Haus Research Briefing

Eleven GTM engineering agencies, one stated criterion: a published price, a statement that there is no setup fee, and a month-to-month term. One point each, ties broken by how many of the 14 ranking lists name the agency. Scores measure what a buyer can verify before a call, not the quality of the work.

  • Sales.co: 3 of 3 — $5,500/mo flat, no setup fee, month-to-month, four channels, replies answered in under 10 minutes
  • RevPartners: 1 — from $12,900/mo and $25,000 fixed-price builds; $5,000 one-time onboarding fee and 6-month initial term on the retainer tiers; named in 7 of 14 lists

Audio briefings from Haus Research, a research firm. Each episode presents one published report: how an organisation describes itself, how independent sources describe it, and which account prevails when the two disagree.
