The problem isn’t that the company failed to be a unicorn. The problem is that the company was declared to be worthless and was given away to the founder (but not employees who built it), but it obviously wasn’t worthless as it’s currently valued at $100 million. Early employee equity was wiped out in the process.
The point is that you can work for a $100mm company, build the foundation of a $100mm company, yet walk away with nothing because the investors and founders can play games with your equity. Unlikely to happen again given how this played out. However it must hurt to be an early Gumroad employee doing the math on what their equity would have been worth today after being told the company was worthless.
