So I recently read The Lean Product Playbook and before actually starting to code an MVP, I want to know if the market really needs the Product. In order to gather feedback I have prepared a Questionnaire. But, I am confused, whether I should open the questionnaire to my network, such as LinkedIn / Twitter & Co. or shall I shortlist customers, schedule calls and interview them.
The former will give me responses quickly, but responses will just be a survey whereas the latter will be more beneficial, may be even probable customer(s), but will take more time.
Question 2: I have made a very hacky PoC and I am thinking maybe code a cleaner mock MVP and record a short screencast just to show how it might look like when working?! Has anyone done that as well? Would that be beneficial?
Something inside me still wants to code the MVP, please suggest what you had done! Especially technical founders.
