Not if you are the one starting the startup and not if they make it easy for Joe American to invest in startups.
I think he means 'get in on the phenomenon in general', not any one particular startup. I mean, looking at the portfolio, I think even with wefunder, most of the companies "look like crap" (although I'm sure that some of them will be alright), and if I could clear the requirements, I'd only invest in two of them.
Investments in early-stage startups are highly illiquid so in most cases, getting in early won't mean a thing because you will never be able to get your money out.
