Most tools give you one forecast and one recommendation. Real decisions are messier. The numbers you put in are guesses, and if a guess is wrong the answer can flip. MARK C is built around one question: what happens if I choose differently?
How it works
You model a decision, add the alternatives, and MARK C runs each option through many simulated futures. It uses counterfactual reasoning, probability models, Monte Carlo simulation and sensitivity analysis. The goal is not only to find the best option, but to show how reliable that choice is.
Four ideas that matter
- Reversal Engine: shows what would have to change for the recommended decision to flip.
- Robustness Score: shows whether the decision stays strong across thousands of simulated futures.
- Weakest Link: points at the assumption your plan leans on most.
- Data Worth Collecting: tells you where extra information would raise your confidence, and where it would not.
Why the weakest assumption matters
Say you are choosing between two pricing plans. Plan A has a higher expected profit, but only if churn stays low. A tool like this would show that if churn rises a little, Plan B wins. Now you know the number to check before you commit. (This is an illustration, not a case study from MARK C.)
Who MARK C is for
Founders, operators and analysts making calls on capital, hiring, pricing or strategy where being wrong is expensive. If you want a quick yes or no, this is overkill. If you want to know how much uncertainty a choice can take, it fits.
