My equity grants as a non-eng (but involved in prod dev) have ranged from 0.05% to 0.6% over the course of 10 years in startups (age 25-35). All Series A to Series B.
My take is that unless you are very good at judging leadership teams and company prospects, that joining a FAANG or a Series C+ scale-up (and even that takes thoughtful research and luck) is the better play.
Early stage at my past grant levels has to hit a unicorn valuation for the equity to match FAANG packages. I'm not even sure a $1B exit is enough after dilution, investor preferences, and god forbid down/flat rounds. Certainly not at the grants that I started at in my career.
Plus keep in mind that FAANG stock also appreciates. I see some folks not accounting for that growth and only startup valuation growth. Comp packages for mid level ENG and PMs are 400-500k / yr, not even including appreciation!
