<insert startup name> has always been amateurs.
In this era of cheap money it's been maddening to see how absurdly incompetent companies can be and still push forward with no consequences.
I've seen teams of people working on credit scoring with no understanding of expected default. They literally just throw data at XGBoost, and couldn't understand why they couldn't find a way to profit off a group of people with a 30% default rate when the upper bound of interest they could charge was 25%.
This pattern is repeated all over startup land (I've also never met a company that knew how to model churn correctly, this is an essential business metric and yet again people throw XGBoost at it), but cheap money means that doing anything is rewarded with more money so every idea seems like a good one.
Crypto companies will be the first to go, but hard times are coming for anyone working at a company that doesn't have a profit.
