I wanted to mention is that you can do 2 pages for the organizational chart and I recommend that you do one page for the hierarchy part and then another that shows how you interact with other departments, investors, clients etc - give them a better idea of who you are interacting with. This is how entrepreneurs generally approach the org chart. It just adds more value for them to see who you’re actually working with rather than you are being managed by person X

If you are a solo entrepreneur or contractor, try this: place yourself at the center of the chart, then make branches representing the various constituents and stakeholders you interact with (for example, clients, suppliers, investors, board of directors).
