Ask HN: How can I convince my coworkers to start a company?

I work at a FAANG and have a lot of side projects that I'd like to try turning into businesses, but I'm having a hard time finding cofounders. All of my close friends work at <large company> however and they all say that the security of the job is why they won't leave even though the product sounds fun and they'd want to work on it. Obviously, this isn't something I can offer. I want to offer something better, however I'm not sure how I can pitch a convincing argument.

So, for those of you who managed to convince a friend or were otherwise convinced, what tipped the scale away from job security?
