For Accelerator Programs, Incubators & Startup Coaches
Give your cohort a methodology that ships.
Most accelerators offer mentorship. Few offer a repeatable method. Subtract to Ship is the four-volume curriculum behind the Startup Burgenland accelerator — where cohort companies reach first revenue inside the program.
The Problem
Mentorship alone does not ship products.
No structured methodology
Most accelerators are a series of mentorship sessions. Valuable, but unstructured. Founders get advice from twelve mentors pulling in twelve directions. Nobody teaches a single, repeatable method for getting to market.
Too much mentorship noise
More mentors does not mean more progress. It means more conflicting opinions, more scope additions, and more founder confusion. The cohort needs a framework for deciding what to ignore.
Companies stall after demo day
The program ends, the cohort disperses, and most companies lose momentum. The ones that survive are the ones with a method they can execute independently. Not a network — a method.
Proof
Battle-tested in a live accelerator.
Felix Lenhard is Program Director at Startup Burgenland, where the Subtract to Ship methodology forms the backbone of the accelerator curriculum. He has coached over one hundred startups since 2015.
The pattern across all of them: the companies that reached first revenue inside the program were not the ones with the most features or the biggest vision. They were the ones that removed the most before launch.

The Offering
A four-volume curriculum backbone.
Each volume maps to a stage of the startup journey. Use them sequentially as your program curriculum, or pick the volume that matches your cohort's stage.
- 01
Validate
The Subtraction Audit. Your cohort learns to audit their backlog, identify what blocks the launch, and produce a one-page Kill List they can defend. The coaching tool for the first four weeks.
- 02
Build
Minimum shippable spec. The stop-line for when construction is done. Rules for keeping teams small enough to ship in weeks, not quarters.
- 03
Grow
Post-launch signal reading. How to choose what to add next, and how to keep the product coherent under five directions of growth pressure.
- 04
Scale
Past product-market fit. How to keep a removing culture alive past forty employees, when founders are no longer in every decision.
