1. Remote is not "from your house". Rent an office near home, walk there.

2. Use video conferencing every day without fail. Something very monkey brain makes a human face you are talking to real, and prevents you flipping the doofus bit on people (and they you)

3. Everyone and everything must be remote-first - business and IT. There is real advantage to walking over and saying hello, shaking peoples hands.

4. Meet up in person and work together (pairing, meetings, clarifications) at least once a week. This basically limits the distance you can all be from each other (roughly two major metro areas apart - London and Paris, NY and Washington)

Ultimately this all costs money. it's cheaper to hire crap people and expensive office space.

YMMV
