Theoretically they should have gotten good help from a CPA by then, but if it's a largely automated business and it suddenly skyrockets, it might be easy to just enjoy the money rolling in without taking it seriously enough.
The more I read about it the worse it sounded.
That one little trick (/s) of developing an audience, especially a devout and loyal audience, is the part that most people are not good at.
I am confident that any 10 year old could sell $100k+ per month online with about a week of training if that was the only requirement and they were allowed to spend $120k. Actually earning significant profits is the difficulty here, and that only gets easier with the standard toolkit of running a successful online retail business: understanding the products, knowing the market, and understanding all the legal hurdles.
This 10 year old sounds like they're ready for the next YC batch lol.
They could have 'earned' hundreds of thousands, only to owe millions.
The craziest part of it was they totally bought into the "super secret" nature of the whole thing. There was a huge amount of family drama when someone in the family mentioned that her brother had a business on Amazon. He said it was top secret and he had access to trade secrets that no one else had.
Having unfortunately been involved on the tech side of MLM early on in my career, it was painfully hard not to point out the predatory nature of the whole thing.
