After sleeping on my answer, I think it is important to think about the potential issues which can arise when:

1. An investor is also responsible for coding the core product. Multiple roles mean conflicting interests - e.g. protecting invested assets versus the risks associated with high growth.

2. A person with a minimal equity stake is responsible for coding the core product. It is easier for a person with only a few percentage points of equity to find a better opportunity or hedge their investment. 5% of a $10,000,000 sale is nice, but it's not going to allow a person to retire.
