Why I Left MentorCruise to Build Kerr University: The Marketplace Problem

The Marketplace Model Solves a Discovery Problem — Not a Quality Problem

MentorCruise and platforms like it solve one problem very well: they help professionals discover mentors they would not otherwise find. That is genuinely valuable. If you are a junior developer in Poland looking for a senior engineer in Silicon Valley to mentor you, MentorCruise makes that connection possible. The discovery problem is real, and marketplaces solve it.

What Marketplaces Cannot Solve

What marketplace platforms cannot solve is the quality problem. When I was on MentorCruise, clients booked sessions with me based on a profile, some reviews, and a listed background. Some of those clients were an excellent fit. Others needed something the platform's matching logic could not assess — a specific kind of CEO perspective, a specific industry depth, a specific coaching style. The platform could not know this before the first session. So clients wasted sessions learning whether the fit was right, rather than doing the actual work.

The Per-Session Incentive Problem

Marketplace mentoring is typically billed per session or per month with a defined session count. This creates an incentive structure that is not always aligned with client outcomes. A mentor who earns more from longer engagements has some incentive to extend the work. A mentor who earns per session has some incentive to fill sessions rather than accelerate results. These are structural issues, not character flaws. But they affect outcomes.

Why I Built Kerr University Directly

Kerr University is built around a different premise: the client gets a Wharton-educated CEO — me — in every session, with no marketplace intermediary, no algorithm, and no platform fee driving up prices. Direct access means faster context-building, deeper coaching, and a relationship that compounds over time. The results I see with direct clients are consistently stronger than what I observed in marketplace-matched engagements, for one reason: the relationship starts with full trust and context, not a profile page.

The Marketplace Is Good For Many Things. Executive Mentoring Is Not One of Them

If you need a tutor for a specific subject, a conversation partner, or a first introduction to a mentor type, marketplaces serve you well. If you need direct access to a Wharton CEO who has led global companies, authored 12 books, and can apply 35 years of real executive experience to your specific challenge — you need something else. That is what Kerr University provides at $125/mo.
