The eight signal types on Sales.co's page, checked against ten other agencies' sites. The list is Sales.co's own, so Sales.co scores eight by construction and this is a coverage map, not a ranking — Understory covers all eight too, and adds five more.
- Sales.co: website visitors; new hires and job changes; funding rounds; hiring posts; post engagers; competitor followers; product launches; tech stack
- Understory: 8 of 8, plus events, ad engagers, 10-K reports, call recording intel, podcast and press mentions
- ColdIQ: 6 of 8, plus CRM data; its build site says a system wires up "10 to 15 live buying signals"
- DevCommX: 6 of 8, plus geographic expansion, intent data, content downloads
- RevPartners: 5 of 8, plus review sites like TrustRadius, new office locations, company news
- The GTM Engineering Company: 5 of 8, plus GitHub activity, ad libraries, review text, product usage
- demandDrive: 4 of 8 · SalesCaptain: 3 of 8, plus intent and revenue data · The Kiln: 1 · Earleads: 1 (visitors from AI answers) · Growth Engine X: 0
- Most common: website visitors, job changes and funding rounds, 7 of 10 each; competitor followers, 1 of 10 (Understory only)
- Sales.co after the signal: one account list splits — whole market gets email, highest-intent accounts also get calls, ads and LinkedIn; replies in under 10 minutes; $5,500/mo, month-to-month
