Six things investors expect you to do without thinking.
Pre/post-money math
Investor %, post-money, founder retention. The denominator that trips everyone the first time it matters.
Dilution through rounds
Three rounds chained. Dilution is multiplicative, not subtractive. The reflex that separates cap-table-literate founders from the rest.
Option pool, pre vs post
The same "12% pool" can cost you 2.4 percentage points depending on which side of the round it lands on.
Exit waterfall
Non-participating "either/or" vs participating "double-dip." Run the math the VC just dropped on you, in real time.
Spanish Holdco exit
1.25% effective tax via Holdco vs ~28% personal IRPF. The difference at a €10M exit is roughly your apartment.
Vested vs clawed
Pre-credit, cliff, leave date. What you keep, what the company claws back, and why vesting isn't a non-compete.
One scenario at a time, scored immediately.
Six drill types. Each generates random numbers — you can't memorize answers, only the math.
Percentages, euros, multi-part questions. Inputs accept European decimals (52,8) and shorthand (1.5M).
The verbal prompt is the part most founders skip. The math is right; the spoken sentence is sloppy. That's what loses negotiations.
Progress saves locally. No signup, no account, no email harvesting. Works offline once loaded.
15 minutes a day until it's reflexive.
5 min — The drill you scored lowest on last time
5 min — One random drill (variety locks the pattern in)
The goal isn't perfect scores in here. The goal is: when a VC says "we're at €7M pre-money with a 12% pool, pre-close, fully diluted post-money" — you've already done the math three weeks of mornings in a row, and the answer arrives before the sentence ends.
I built it for myself first.
So I built a daily drill. Six scenarios that map to every term sheet I'd encounter. Random numbers, immediate scoring, verbal prompts. After three weeks the leaks closed and the math arrives before the question finishes.
If you're a founder prepping to raise and you can feel the same gap — this is yours. Free. No signup. Built honest.
Start with one scenario.
It takes a minute. Either you'll be right, or you'll know exactly what to drill tomorrow.
