That's the main reason I avoid using any products from startups. I just know that in a few years, the company will die out or exit, and in both cases product I would rely on will be discontinued, or shittified by the new owner.

The only exceptions are open source products with a healthy community, where I can evaluate their possibility of survival after vendor shutdown, or commodity services, where I can count that I could replace them with something similar with a minimal effort.
