Why your best sales rep will likely make a poor manager

Executive overview

Top salespeople are systematically promoted into management roles they are ill-suited for, because the skills that drive individual sales success — curiosity, rapport-building, selfishness with time — are largely orthogonal to what makes a great coach and people manager. Industry data shows an inverse correlation between rep performance rank and management effectiveness, mirroring patterns seen in professional sports. The solution is not to stop promoting high performers but to create a structured audition process that lets candidates self-select out before they damage their careers or the team. The real risk is not the bad manager you make — it is the top rep you lose when you promote someone else.

Why top reps fail as managers

• Great reps succeed through personal execution: rapport, discovery, accountability, and sometimes aggressive self-interest.
• Great managers succeed through diagnosis: reviewing many calls, identifying skill gaps, and coaching to each individual's learning style.
• These two skill sets rarely overlap — the same inverse pattern holds in creative work and professional sports.
• Michael Jordan had an unmatched feel for basketball but could not translate that into coaching others.

The promotion trap

• Reps expect management to be the only growth path after two to four years of strong performance.
• Leaders default to promoting the best rep because replicating that output seems logical.
• Both pressures combine to put the wrong person in the role almost by default.
• Most newly promoted reps eventually self-report: more stress, less money, longer hours, and a desire to go back to selling.

Hiring strategy: internal vs. external

• Promote roughly 80% of managers from within to preserve growth culture and retain talent.
• Hire roughly 20% from outside to inject knowledge from high-performing orgs (Stripe, Klaviyo, Twilio).
• External hires also serve as a buffer when internal talent is not yet ready to support rapid headcount growth.
• The speaker's early mistake at HubSpot was promoting the first 20 managers entirely from within.

Building a manager audition process

Rather than awarding management titles based on quota rank, run candidates through a structured sequence:

1. Hit quota three consecutive quarters — establishes baseline credibility.
2. Complete a leadership training programme — weekly short readings (e.g. Harvard Business Review e-books on conflict management, delivering feedback) followed by 30-minute role-play scenarios.
3. Hire and onboard a new rep under supervision — tests real hiring judgment and coaching ability before the title is granted.

• The role-plays and training cause roughly half of interested reps to self-eliminate — they realise the job is not what they expected.
• The hiring step lets the leader coach the candidate on judgment without allowing a bad hire to land.
• Candidates who complete all three steps are pre-qualified for the next opening.

Retaining the reps you do not promote

• A rep like "Peter" who is passed over for "Susan" (ranked eighth) will feel overlooked and may quit even though the right person was chosen.
• The audition process gives Peter a transparent, merit-based explanation for why he was or was not selected.
• If Peter opts out of management himself, he still needs a growth path or he will leave within two to three years.

Building an individual contributor career ladder

• Segment markets (BDR → SMB → mid-market → enterprise) to create a natural 10-year progression reaching seven-figure earnings.
• Where only one segment exists, create tiered levels (Tier 1, 2, 3) tied to cumulative revenue milestones, customer retention thresholds, and incremental rewards (stock options, base increases).
• Salespeople are competitive — a visible, structured progression keeps them engaged without requiring a management title.
