Yes a minimum marketable product sounds the better option. And i totally agree customers would be put off if they were handad a half finished product while the rest was being developed.
At the same time, i do need to have something to show to the VC s and others, so they can visualise what the app should look like.
Like you said i have been drawing out the design to show people. There s another software expert i ve been speaking with this past week, and i ve shared a few ideas with him about the layout of the main screen, a d the 'layers' the information will be divided into.
I might try and upload some of those on here.
If you re interested, there s also the Linkedin group where a few contacts have gathered to discuss. It s on the links above. There are 2 potential developers, and I m definitely offering equity share to all engineers who are interested in getting involved.
