AI & AUTOMATION | ADVISORY BOARDS | FINANCE & GOVERNANCE

i.

Advisor, Operator, and Founder of Tether Business Solutions; former PwC Partner.

For more than two decades, I advised founders, executives and boards through IPOs, acquisitions, transformations, and the moments when a decision could not be undone.

I do that work from the outside now — and I help build the systems that let a ten-person company operate like one with a hundred.

The answer is usually available. The judgment is the scarce part.

"Most of what goes wrong was visible early. Nobody had the time to look."

About

Twenty-two years inside the institution.

Then a decision.

I spent twenty-two years at PwC advising executives, founders, boards, and investors through IPOs, acquisitions, governance challenges, and periods of significant change. In 2017, I was admitted to the partnership—an achievement I had spent my career pursuing.

At the end of 2025, I made the difficult decision to leave.

That experience reshaped how I think about leadership. Success doesn’t eliminate uncertainty. It changes the questions leaders have to answer.

Today my work takes three forms, all of it the same questions asked at different scales. I founded Tether Business Solutions, where I build and run AI & automation systems for underserved, owner-led businesses. I serve on a small number of advisory boards. And I take on selective finance and accounting engagements during consequential moments.

What connects them is judgment. The information is rarely the problem — deciding what to do with it is.

A periodic essay about starting over in the middle of life. What reinvention costs and who pays it with you. What holds up when the title comes off. Some of it is work. Most of it is wider than that.

Written for people, not companies. It’s here because the way I think about consequential decisions didn’t come from a framework. It came from making a few of my own.

Most people who reach out aren’t looking for answers.

They’re looking for someone who’s seen how these things tend to go and who can help them decide what to do about it.
