What We Learned Building Lead Scoring for a Sales Team That Didn't Trust It

The technical part of lead scoring — weighting firmographic and behavioral signals into a single number — is the easy part. The hard part is getting a sales team that's been burned by a bad scoring model before to actually change how they prioritize outreach.

We shipped the model alongside a transparent breakdown of why each lead scored the way it did, not just a black-box number, and ran it in shadow mode for a month so reps could compare it against their own instincts before it touched routing.

By the time it went live for real, the sales team had already seen it agree with their own judgment often enough to trust the edge cases where it didn't — which is the only way an automation like this actually gets used.
