For the first dot-com boom, I did Downside&#x27;s Deathwatch[1], which did exactly that for public companies. (Companies IPOed earlier in that boom, often before profitability.) For a public company, SEC filings give anyone enough info to make that calculation.<p>For a private company, it&#x27;s much harder to tell from the outside. Any CEO who doesn&#x27;t know how many months (days?) of cash they have left is hopeless.<p>[1] <a href="http:&#x2F;&#x2F;www.downside.com&#x2F;deathwatch.html" rel="nofollow">http:&#x2F;&#x2F;www.downside.com&#x2F;deathwatch.html</a>
