An MVP is the smallest functional version of a product that lets a team test its core hypothesis with real customers. The point is not to ship a stripped-down product; the point is to ship the smallest thing that produces a meaningful learning signal about what users will actually pay for or repeatedly use.
A good MVP is paired with a single, sharp question, usually about willingness to pay, retention, or activation. Once the question is answered, the team either iterates on the same thesis, expands the product, or pivots to a new one.
