Graz, Austria — Builder // Author

Find what to cut.
Ship what matters.

The Subtraction Audit for founders whose product is built but revenue hasn't kept pace, and for leadership teams running more projects than priorities. I go through your products, processes and priorities, name what is slowing you down, and leave you with one plan your team can run on Monday.

20 years of building products and companies. 100+ startups coached across my career, 50+ of them at Startup Burgenland, the accelerator I built. 12 products shipped to 50+ countries and sold. Three books published. One method behind all of it: Subtract to Ship.

The Method

The prototype of our best-seller had 14 steps. The version that sold had 5. Every product, company and accelerator I've built followed the same pattern: strip away everything that doesn't serve the outcome. I call it Subtract to Ship.

The Subtraction Audit

One engagement. One plan.

What you get

A written list of what to stop, what to keep and what to finish, ranked by what it frees up. Your team reads it in twenty minutes.

How it runs

Interviews with the people who do the work, a review of the numbers, one working day with the leadership team, and the plan typically five working days later.

How fast

Two weeks from first call to delivered plan. Thirty days later we meet once more to check what actually got cut. That meeting is included.

If it doesn't fit

The first call is free and I tell you on that call whether the audit will find anything. If I don't think it will, I say so and we stop there.

Felix leads with intention, builds trust across teams, and keeps progress measurable and purposeful.
