If you're in the US (or able to get a visa to work here a few years – admittedly a much harder prospect recently than it should be) and have technical skills, it's not difficult to find a job that will allow you to save $100k in 2-3 years if you're willing to live very frugally. At that point, you'll have the freedom to bootstrap your own company without giving up any equity.
