Twenty years. 101 sales teams. $500M closed for clients. The same mistake every time.
VPs of Sales pick reps using DISC, Predictive Index, Caliper. Tools built for HR. Tools that tell you how someone behaves at a dinner party. Tools that were never built to predict whether your rep picks up the phone Monday morning when the pipeline is dry.
What we believe: sales isn't behavior, sales is wiring. Wiring is the instinct that fires when the buyer says no. The reflex to call the deal that's slipping. The competitive edge you can't coach into a rep who doesn't have it. And here's the part everyone misses — you can measure it.
Twenty years across 101 sales teams, and the story barely changed from one to the next. A VP would lose their fourth rep of the year and pull up the file. The hire had passed the interview. They'd passed the personality test. On paper they were a clean, high-scoring yes. And then the pipeline went dry, and the calls stopped. Not because they couldn't do the job — because something underneath wasn't built to keep doing it when it got hard. The test measured how they came across. It never measured whether they'd come back Monday.
DISC, Predictive Index, Caliper — they're not bad instruments. They're the wrong instruments. They were built to describe how a person behaves across any role, in any room. That's a useful thing to know. It is not the thing that predicts a close. Behavior bends to the room. Wiring doesn't. Measure the style and you learn how someone interviews. Measure the wiring and you learn whether they'll hit quota.
SalesFit isn't an assessment. It's how operators hire and coach reps who actually close. Built by an operator with quota on the line. For operators with quota on the line. DISC tells you who someone is. We tell you whether they'll close. — Kayvon Kay, Founder, SalesFit.ai
What does "sales is wiring, not behavior" actually mean? Behavior is what someone does in a given moment — and it changes with the room, the mood, and the incentive. Wiring is the instinct underneath: the reflex that fires when a buyer says no, the pull to chase a slipping deal, the competitive edge that won't sit still. Personality tests like DISC describe behavior. SalesFit measures wiring, because wiring is what holds up on a dry Monday when no one is watching — and that's what predicts whether a rep closes.
Why doesn't DISC work for sales hiring? DISC, Predictive Index, and Caliper were built for general HR use — to describe how someone tends to behave across any role. They were never designed to answer the one question a sales leader is actually asking: will this person build pipeline and close under pressure? A behavioral style tells you how a candidate comes across in a meeting. It does not tell you whether they'll survive rejection or push through a bad quarter.
Can competitive drive really be measured? Yes — and that's the part most people miss. The instinct to compete, the resilience to absorb rejection, and the economic motivation to push through a tough quarter are not vague intangibles. They're consistent, measurable behavioral dimensions. SalesFit scores them directly, alongside archetype fit and seven Deal Killer risk patterns.
Who is SalesFit built for? SalesFit is built by an operator with quota on the line, for operators with quota on the line — sales leaders and VPs who hire and coach reps and live with the results.
