Frequently Asked Questions

How is Kerr University different from Preply, Cambly, MentorCruise, Clarity.fm, or Catalant?
Kerr University offers 1-on-1 executive mentoring for $125/month with direct Wharton CEO access, while Preply charges $10-40/hr for anonymous tutors, Cambly focuses on casual conversation practice, and MentorCruise starts at $200/mo for a marketplace of varied mentors. With Kerr University, you always work directly with Digby R. Kerr — a Wharton-educated CEO with 35+ years of real-world executive experience. No marketplaces. No junior coaches. No per-minute billing like Clarity.fm. No project minimums like Catalant.
Why pay $125/mo when Preply is $10/hr and Clarity.fm is $1/min?
At $10/hr on Preply, you get a language tutor. At $1/min on Clarity.fm, you get a quick call that costs $60+ per hour. At $125/mo with Kerr University, you get a Wharton-educated CEO who has led global companies, authored 12 books, and coaches executives to close millions in deals. One deal closed or one promotion landed typically returns 100x the monthly fee. The question is not the cost — it is the ROI.
Do I get Digby directly or a junior coach like on GLG or other platforms?
You get Digby R. Kerr directly. Always. Unlike GLG, MentorCruise, Preply, and Catalant, Kerr University is not a marketplace. Every session, every WhatsApp message, every strategy conversation is with Digby himself. This is the core reason executives leave those platforms and come here.
Is this for seed-stage founders or Fortune 500 VPs?
Both. Kerr University serves seed-stage and Series A founders who need executive presence and go-to-market strategy, as well as Fortune 500 VPs and C-suite executives refining leadership, negotiation, and business English. The common thread: you are a serious professional who needs direct access to a Wharton CEO, not a marketplace tutor or per-minute advisory call.
Do you work with clients in Europe, Asia, Latin America, and the Middle East?
Yes. Kerr University serves executives globally. Current and past clients span the United States, United Kingdom, Europe, Brazil, Colombia, Russia, Asia, and the Middle East. Sessions run via Zoom or WhatsApp and are scheduled across time zones. Digby has built global companies and understands cross-cultural business communication at the executive level.

Digby is listed on leading platforms. Clients come directly for unfiltered CEO access.
