When interest rates are low the difference between a dollar now and a dollar later (discount factor) is negligible. In this environment the math favours businesses that can grow revenue really fast.
Now that rates have risen, the discount factor has become more expensive and so firms want their dollars today. A lot of companies need to come up with a path to profitability quickly to shore up their stock prices and have a sustainable business.
