In a documentary about them putting Dwarf Fortress on Steam Tarn talked about how he had to split the $7 million first payment from Steam with his brother and it turned out the easiest way was to just use the bank app.
You are thinking of the NoClip documentary! It is fantastic and well worth your time.

I’ve never received $7M but a few times I’ve handled large sums (when buying a house and previous startup exit) and it felt so weird to be how completely normal it was. Like just… oh yeah go ahead and write a cheque for six figures. Or do an e-transfer into your chequing account for six figures. It felt like… no there has to be a whole special world for large sums, no?
