We have on institutional VC and no outside board. Remote is more and more common especially with engineering and support teams so they didn't have any pushback. I think if we weren't performing as well they might have more concerns.
The first thought is to have a successful compang that'd be worthy of investment. Next, show they've thought about the trade-offs, which I'd say these docs prove. Lastly, don't hear no when a VC says they don't invest in remote companies, but be prepared the address in a short response how you understand why they feel that way, why it is a non issue, and then leave the door open to let them changd their minds.
Looks like you're developing 3D tech. Maybe the VC's in that space believe physical interaction is important since it's a nascent tech without a proven business model.
