This is incredibly valuable! The power law simulator caught my eye because most founders dunno how concentrated VC returns actually are until they see the numbers. I've walked thru pitch decks where teams cite TAM/SAM/SOM but skip unit econ entirely, then wonder why investors push back on scaling plans. The sequencing here matters more than people realize, solid unit economics should absolutley come before aggressive growth tactics.
