Check out Levels.fyi and Blind. If you're in NYC, it's definitely possible to hit above $180k at a Series B-ish startup. It goes much higher as well with FAANG and some of the unicorn level startups as well.
What I'm questioning is if focusing on honing my "startup" skill in regards to bringing something from zero to 1 or clamping down on my main gig and going for incremental raises? PG's writing on the subject says to not maintain side projects, but obviously this is what a VC would want to impart. I also generally see starting a number of small but profitable businesses as a more efficient path to wealth instead of chasing ultra high salaries (frankly, I'm not sure I'm smart enough or improve fast enough to reach those salaries).
