Becoming a founding engineer is a wealth-building, passion-for-your-work risk, not a pure salary optimization decision. HN never seems to understand this. If you’re optimizing for stable salary, go for the FAANG position. You’ll be comfortable, but you’ll most likely never be able to fly private, and you’ll have to be OK existing as a cog in a massive machine. Plenty of people are ok with this. These people should not be founding engineers.
