Why I left consulting to find out if any of it works

20 March 20262 min read

Advising is safer than building. That's the problem. A year in the founder seat has made me a better advisor — because I've been the founder who can't afford another meeting.

Around the end of 2024 I started asking a question that refused to go away. If I'm honest — I mean, really honest — would any of the advice I'd spent the last decade producing survive contact with my own skin in the game? Would I bet my cash runway on it? Would I still recommend the three-quarter roadmap to a founder whose seed money ran out in four months?

The answer I kept arriving at was 'mostly'. Which is a more troubling answer than 'yes' or 'no'. The parts that would survive were the parts closest to operating reality. The parts that wouldn't were the parts that assumed a luxury of time or budget that founders don't have.

What changes in the founder seat

Within a month of leaving, I noticed the calendar change. In consulting, a Tuesday morning with nothing on it feels like an opportunity — space to write, think, prepare. As a founder, the same Tuesday feels like evidence you're burning runway without progress. The asymmetry is real. Founders pay by the week, not the hour.

I also noticed how much of the advisory I'd produced assumed you could delay a decision. 'Let's run a structured experiment', 'let's revisit this in Q2', 'let's book a workshop with the team'. All reasonable in a consulting frame. All unaffordable when the next board meeting is in seventeen days and the previous one ended with a number you haven't hit.

Why this made me a better advisor

The best thing that happened to Marga Haus was that I stopped being able to afford my own frameworks. What's left after that filter is the set of things that actually move the business in two weeks. Not in a quarter. Not after a research phase. In two weeks.

MedClear is live. MVP Guru is live. Both have runway anxiety. Both have had weeks where nothing measurable moved and I had to decide — honestly — whether the thing I was working on was worth another week of cash.

When a pre-seed founder now asks me whether they should spend a sprint on X, I'm not reading it out of a playbook. I'm answering from last week.

Advice you've never had to live by is cheap. Advice you've had to live by is expensive to buy and cheap to take.

Found this useful?

Thirty minutes. Free. No pitch deck.

If the diagnosis is clear without me, you go do it. If not, we talk about the sprint. Either way, the first call takes 30 minutes and costs nothing.
