People ask us all the time why we only hire in the North America (realistically, just the US)
"I work on US timezones" "I've been working with US teams the last X years"
The thing is that time management is not the same as energy management. I know coz I for a few weeks at a time, I have worked out of other timezones and it sucks. Yes, people can do it but it sucks.
And we don't want anyone coming to work feeling it sucks.
We make decisions throughout the day, especially in our standups, and we want our team to be their sharpest when we are making them. We want everyone to feed off of each other's energy and when they are ready to stop for the day, it's because all their coworkers are too.
Our team is "remote by not async", we are fully synchronous by design. Conversations are on Gather where people can talk to each other anytime, nothing to schedule. [Additionally, remote works for us only because we hire staff+ level only. I don't think remote works well for people right out of college or earlier in their careers.]
People can mange time but there's no real way to battle the sun and bring your best work energy at midnight. Circadian rhythms are real and we've evolved with them.
Global teams work when your coworkers are local and the larger company is global. That's a large company thing. Global doesn't work for smaller, fast moving startups.
