@genmon you could prototype quickly and explore with Google AppSheet. One Google Sheet with 3 worksheets. Put data in sheet 1 and 2 and make a separate AppSheet for both. In sheet 3 make a third dataset populated from the first 2 and then make a separate AppSheet for that. You could even populate back to sheet 1 and 2 from sheet 3. You could build a simple 2 sided market with a market maker dashboard… now imagine sheets 1 and 2 were populated by 3rd party apps and you can still be a market maker with sheet 3.
@genmon Doesn’t matter if the above is perfect, most importantly with Google Sheets and AppSheet you can do 100 prototypes between now and the new year for free and learn something on every turn… make > show > learn iteratively as fast as you can.
