The most famous example is probably Gitlab (https://handbook.gitlab.com/handbook/company/culture/all-remote/asynchronous/)
Since their IPO the work environment seems to have deteriorated though (https://old.reddit.com/r/devops/comments/152o4bb/what_the_hell_is_going_on_at_gitlab/)
Curious to see if other people have any experience of real asynchronous work culture?
I was scheduling calls from EST with people on AEDT 20 years ago. Companies having a global presence isn’t a new issue. Everything is a trade off and sometimes the cost of asynchronous work communication is beneficial.
