StartUp Coach.
No Fluff. All Force.

I work with first-time founders, technical founders, corporate execs, and academics stepping into entrepreneurship. Seed to Series A.

Coaching isn't about teaching. It's about pressure.

If you're ready for pressure, not lectures, and ready to run....

You Don't Need

another "teacher."
You need a second brain.

"However you stumbled into entrepreneurship, however you found me, and whatever you are looking for, know this, every founder's journey is different. But no great founder gets there alone."

What I Actually Am

I'm not just a coach or advisor. I'm a force multiplier for your vision.

StartUp Coach? Yes.

But coaching implies a teacher-student relationship. This is peer-level collaboration.

Mentor? Sure.

But mentorship suggests occasional guidance. This is consistent, engaged support.

Founder Coach

That's closer. All the value to help you achieve your vision. I'm obsessed with your success, not my role.

"I am all in on one thing. Your outcome."

What Founders Say

Take The First Step

Book an Intro Call

It's one hour. No pressure. No homework. No obligation. We spar. We explore. We figure out if we like working together.

This is peer-level - not student/teacher. You'll walk away sharper even if we never speak again.

One Job on That Call:

We figure out your North Star.

Clarity on your ultimate destination and why it matters.

We sketch the broad steps to get there.

A high-level roadmap that makes sense for your situation.

Then we throw that map out the window.

And work out what you have to do right now to even have a shot.

Mapped with just the right amount of chaos.

Energy and opportunity to let you take the bets you want to take - not just the ones you're forced into.
