I don't think you can 'always' get acquihired. You've got to play your cards right, get just the right team, and have people that the acquihiring company wants. I'm wondering if the acquihire is as easy as most believe it is.
Nope. As long as your idea is reasonable(which is a high chance assuming you have your head on straight which is clearly not the case if you're doing stuff like developing an 'elixir for immortality' or building a 'google killer'), you have some semblance of a product and at-least a seed round in funding, getting acquihired is not at all a problem. Trust me, I've already gotten offers for acquisitions and I've barely begun fundraising.
