The honest version
Build thecompany.Keep your mind.
For founders with real businesses, real pressure, and decisions that are too important to make alone.
3 exits / MIT Sloan / 750+ founders mentored
The part nobody says out loud
Revenue.
But is it a business?
A team.
But it all depends on you.
Momentum.
But too many decisions alone.
The problem with advice
You don’t need more advice. You need better judgment.
The expensive way
Advice earnedthe expensive way.

The wins changed my life. The failures nearly ended it.
Twenty years of building. Three exits. Six years teaching entrepreneurship at MIT Sloan. I work directly with founders on the decisions they can’t make alone.

Before you reach out
A few thingsworth knowing.
Founders with real customers, real pressure and a business that still runs through them. If you want an honest outside view rather than reassurance, it’s for you.
One paid session: 90 minutes on your actual problem. You leave with something useful whether or not you go further. If a mentoring seat is free and the fit is right, that fee becomes part of month one.
Direct, ongoing access to Charlie for the decisions that matter. Not an agency, not a programme, not a team of juniors. Charlie works with five founders at a time, maximum.
That’s common, and it’s usually the point. Bring what feels wrong. Finding the real bottleneck is the first part of the work.
One-on-one mentoring, month to month, built around the decisions in front of you. Seats are limited to five and don’t turn over often.
Bring the thing you’ve been circling.
Let’s talk it through.
