Please read before adding an option.
Add single companies as options. Do not add classes of companies (e.g. "YC funded" or "AI startup")
Put the full URL in the option. This is to avoid ambiguities.
After adding an option, add a comment below describing what you know about the valuation. Ideally, include a link to the most recent founding round.
Closing loopholes
The biggest loophole is using independent contractors. Ultimately, I will make the final decision. If a company uses contractors as a substitute for employees, then it will not qualify. If a company uses independents in the typical sense, it will qualify.
The $1 billion valuation is determined by a funding round, the price on a secondary market (for a private company), or the share price (for a public company).
I may bet in this market.
