If you understand well the Lean Startup, in fact, everything in your business model should be Minimum Viable:

-MV Product / MV Value Proposition

-MV Segment

-MV Distribution & Communication

-MV Revenues

-MV Core Competences/Skills

-MV Partnerships

-MV Cofounder team

-ect.

Just like babies are cute Minimum Viable Humans, your startup (newborn social organism) must be cute enough to gain the love of a pitiless World.
