We generally do our standups with the cameras off because we're screensharing the JIRA board, but every other meeting is highly encouraged to have your video turned on. This was a decision made back in March when we shifted to full remote.

Personally, I find it really good for maintaining a personal connection to co-workers when there is video.

(I should point out that all of management from the CEO down to the Engineering Managers all turn on their video so it sets the expectation. Also, it's startup, so we all know each other really well.)
