Yes I've done that manually. In my head I would love for it to be something even more collaborative 'Wikipedia-style' and people would help keep the numbers up

Yes I've done that manually. In my head I would love for it to be something even more collaborative 'Wikipedia-style' and people would help keep the numbers up to date. Of course that could only work for popular companies if there is enough interest about their business. For smaller businesses it could be cool to have templates like "pizzeria business plan" that people could "fork" and input their own numbers. Perhaps reuse some variables across the board such as "cost of tomatoes" instead of everyone doing their thing separately on Excel.
