At least in the tech industry that doesn't apply if the investors believe that the technology or application is promising enough. Look at Uber's example. They lost very large amounts of money for many years before turning a profit. They were able to do this because the investors kept sustaining them through their unprofitable years.
The same thing has been happening for years with the AI companies. I heard a while back that OpenAI wouldn't turn a profit on their services even if they charged end users $100/month.
