For comparison, Etsy gave me an offer earlier this year that was $185K, and came out literally in the week they had layoffs, and Google gave me an offer earlier this year that added up to about $215K (base + 15% bonus + RSUs which have an obvious nonzero cash value), with an expectation of year-over-year growth. (The actual job I accepted was higher than either of these.)
I think GitLab's numbers make sense in several markets but not in NYC and probably not in SFBA either. To be fair to them, there's no good reason to pay someone market rates for those cities when they're hiring a remote workforce, but the fact remains that they're significantly under market and probably losing out on good candidates as a result.
