Maybe we read different articles, but "Build an initial product" is what he said to do _after_ the hypothesis testing.
This is why the article read fairly false to me, not that there wasn't the odd nugget of value, but coming up with a new MVT, is just adding to the confusion.
You did, but your quote comes directly after he said:
"Once you’ve finally tested enough hypotheses to have more confidence about your product viability, then go to the next steps:"
The MVP is the next step and it distinctly different from what he calls an MTP.
An MTP is not a useable product, it doesn't have a login, stack or maybe any code at all.
