One of the co-founders is very big into &quot;lean&quot; and doesn&#x27;t think any type of business plan should be written, while another co-founder believes at least some sort of light (or &quot;lean&quot;) plan should be written. If that is the case, should the lean business plan be written as an internal compass for the founders or directed at early potential investors?
