Coachability — not prior experience or charisma — is the strongest predictor of sales success

By Mark Roberge · Ex-CRO HubSpot ($0→$100M+); HBS Senior Lecturer · 2026-03-03 · book · The Sales Acceleration Formula — five-trait sales hiring scorecard

Tier A · TL;DR
Coachability — not prior experience or charisma — is the strongest predictor of sales success

Claim

Sales success is a function of system design, not individual talent. Roberge's data-driven hiring scorecard rates five traits 1-10 through structured behavioral interviews: Coachability, Curiosity, Intelligence, Work Ethic, Prior Success. The most counterintuitive finding from scaling HubSpot from $0 to $100M+: coachability, not prior experience or charisma, is the strongest predictor. Hire coachable, train with structured curriculum, manage through metrics, and the system produces top performers.

Mechanism

Five interconnected formulas: Hiring (5-trait scorecard), Training (structured curriculum organized around buyer personas + journeys, certifications with pass/fail gates instead of time-based ramp), Management (coach against 1-2 specific metrics where each rep underperforms peers, monthly coaching plans), Demand Generation (formal SLAs between marketing and sales), Technology (instrument every buyer interaction to feed all four prior formulas — compounding improvement). Coachability is upstream because it's the input that makes the other four formulas actually compound on the rep.

Signals

Counter-evidence

Some enterprise-sales motions (very large ACV, multi-year cycles) genuinely depend on senior reps who bring relationships and domain depth. Coachability-led hiring at the senior level can under-rate the network the rep already brings.
