If the MVP finds product market fit and the market is large enough, then the economic incentive to finish the remaining 20% will exist.

If the market isn’t large enough, then the customer still got 80% of the value whereas in the authors idealised world, they likely wouldn’t have gotten anything at all, since the minimum cost to develop it was 5x higher (assuming 80/20 holds).

Overall it seems we’re better off with startups following the Pareto principal than not following it, and the authors real issue is just with bad product management decisions afterwards.
