HeatCheck vs. 6sense.
6sense is an enterprise intent platform built around third-party, account-level intent. HeatCheck is first-party and person-level: it scores the real people engaging with you, at a price built for teams below the enterprise tier.
The core difference
6sense aggregates third-party intent signals to tell you which accounts are in-market, which is powerful at enterprise scale and priced accordingly. HeatCheck takes the opposite approach: it scores the first-party engagement of specific people with your own content and posts, resolves them to your CRM, and acts on the individual, not just the account.
What HeatCheck does differently
First-party, not third-party
It scores real engagement with your own posts, webinars and site, not aggregated intent you cannot see.
Person-level, not just account
It knows which individual is engaging, and drives a task to their owner.
Priced below enterprise
Usage-metered on Waldo credits, so a small team can afford it.
Transparent signals
Every point is an auditable, first-party event.
