Work at the intersection where the technical hits the business

A technical-business decision you want to think through better. Or a team that's lost the thread with the business. I work on both.


I'm external. I don't diagnose or impose — I create the conditions for you or your team to reach the conclusions on your own. For one decision: Sparring (90 min, €150). For a team: Boring Room or Facilitation Program, we'll set up a discovery call. The D4S framework you can try free below.

Bringing a team, not an individual decision? Book a discovery call — Boring Room or Program, depending on your case.

How I work

Entry, escalation, depth.

Three productized formats. The first is for you alone. The other two are for when you already have a team and the decision isn't only yours.

D4S — four filters and a Skip default

The tool I use inside every Boring Room and every program. Not sold. Not certified. Try it on a decision you're weighing before you book a call.

D

Differentiation

Differentiation customers actually feel.

Would they mention it in a review?

D

Dollars

Impact on revenue, cost or runway you can model.

Can you defend the math out loud?

D

Delight

UX improvement users notice.

Or is it just developer experience?

D

Defense

Protection against an identified, plausible risk.

What's the concrete threat?

You bring the decision that won't close. I bring the pattern: what teams like yours did when they hit this wall, what unblocked them, what sank them. If there's no fit, I'll say so on the call.
