No necessarily. An economy can be sustainable even if all companies grow all the time. You just need to allow that companies fold now and then and close down. Then the market place opens space for remaining or new companies to grow. This is not just fantasy, it's how you keep cleaning up. (It does not imply that the economy as a whole keeps growing. That's a different matter altogether.)

Nature works like this too, by the way. Go to tour nearest forest, all plants keep growing as long as they are alive. But they have a limited lifetime and are broken down once they die. Which allows new ones to flurish (and grow).
