Plenty of tech companies have done just fine skipping VC money, or delaying it until they had maximum leverage, like GitHub or Transmit.
Autodesk isn't really interesting here, though. They IPO'd almost 40 years ago at a tiny fraction of their current value, and that tiny fraction is the only number that matters. Anyone could've jumped on at the IPO and still realized 99% of that $47 billion. The investors missed out, but it wasn't some big whiff. The IPO was mediocre by today's standards.
