I set up a Share Pool for my General Partner entity to issue to Venture Partners. What happens if I don't issue them all?

If you don't issue all the shares in your Share Pool to Venture Partners, those shares simply remain unallocated. They can be issued at a later date to new Venture Partners or other team members if needed.

It's important to note that unissued shares from the Share Pool are not considered when calculating distributions or voting - such shares are not issued and/or outstanding for these purposes. Unissued shares are also not automatically re-allocated to the General Partner entity.
