Ask HN: What is the most valuable remote-friendly software company?

There are clearly many developers enthusiastic about remote work, and articles about how this company I've never heard of or that other company I've also never heard of are so successful being remote-first. It seems like the big four/five are remote tolerant but far from enthusiastic about it. Are any of the unicorns secretly or openly remote-heavy? Is Basecamp the biggest all-remote software company?

(To be clear I am not trying to pass judgment; just curious if it correlates more with lifestyle work than big exit work.)
