I quoted directly from the article. MVP is built after the hypothesis testing, but it’s still a test, a test of the independent hypotheses combined into a material product.
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.
