How to choose by your profile
scope under audit-based scope, team under 5: Waalaxy or Lemlist + Apollo Free. Expect to manage it yourself. Limited volume.
scope audit-based scope, team 5-20: Clay + Instantly + Kaspr. A powerful stack but requires at least a growth engineer.
audit-based scope audit-based scopeno in-house expertise: Lead-Gene. A complete machine operated by experts, results guaranteed by D+30.
scope above audit-based scope, large team: Cognism + 6sense + La Growth Machine. An enterprise stack, requires a dedicated RevOps team.
The golden rule: buy a results machine, not a tool to configure. Tools effort less to buy but 3-10× more in total effort (time, errors, training). For your specific sector, see our lead index benchmark by sector 2026.
