If I would want to invest I would need two things:

1) A document that explains how you want to achieve what you described in your OP technically: Explained as detailed but at the same time as easily as possible (NO hiding behind fancy words). For example: How is your "POS 2.0" supposed to work exactly??

2) A presentation of the whole team, at best where all relevant team members are publicly known.

Do you have such documents?
