His biography doesn't mention any others, and did go on about how they barely had an office.

Sorry, $28,000 is not restricted to wealthy investors. You can't buy much of a business for $28,000. Business ventures are always uncertain. The median house in 1995 was $140,000. The median salary then was $27,845.
The idea that $28,000 was some stratospheric investment in 1995 is simply not true.
