This framing assumes that venture capital is both efficient and perfect at identifying potential for massive growth. In reality, there are many technology companies with potential for massive growth that are under-appreciated by the venture community - they don't fit into the right boxes, and if they were to get on the "fundraising treadmill" as the OP describes it, they'd be stuck in a situation where they're forced to spend aggressively without being able to rely on future fundraising making that burn sustainable. The good news is that would-be competitors would be in the same situation. So it's very possible for such a company to think like a startup in terms of its goals, but move at a more sustainable pace than if it were given hundreds of millions to burn. And those startups can still raise from VC when they've proven out their model, if they choose to do so - but it's important that they have a path to success as a startup that doesn't require those levels of cash injections.
