Menno Dellisse

Growth mentoring for CEOs who have outgrown the identity, the systems and the advice that got them here.

The question in the room no one wants to ask. That is where we start.

What a CEO can’t say out loud inside their own company, they can say to me.

For close to two decades, I sat in senior and board-level seats at Mastercard, UBS and Le Pain Quotidien, creating, transforming and expanding businesses across the US, Brazil, Asia and Europe. Earlier, I ran and restructured Sip-Well Germany through its acquisition by Danone. Somewhere in there, advising people became the work I cared about most.

  • A company rarely grows past the person leading it. That’s why this work is never only about the business.

  • Whether the question is about how to grow or about what to protect, you get a clear view from me, not a hedged one.

  • In several of the companies I work with, part of what I earn depends on how the company does. This isn’t a walk-away consultancy.

He doesn’t fix your company, he grows the person running it.

    Menno was my mentor through the most demanding years of Dog Chef, and the best way I can describe what he does is this: he doesn’t fix your company, he grows the person running it.

Questions people ask.

Before you write. If yours is not here, it is a good first line for the message.

Let’s talk.

Reaching out is the hard part. After that, you get me directly.

Tell me where the company stands and what’s on your mind. Three lines is enough, I’ll read all of them. If it’s not a fit, I’ll say so, and I’ll usually know someone who is.
