Sure - although the amount of upfront work required varies with your definition of "Minimum" and "Viable".

I've done full-cycle apps with branding, architecture, UX, QA, promotion, etc. and yes they start at $30k - but they're finished polished products, while the discussion here seems to be about MVPs.

As I said above, the biggest conflicts I see between developers and clients are over the meanings of "Minimum" "Viable" and "Product".
