What's the right level of communication you need to have with your manager?

It's been almost two years since I have been working for a startup and I report to a founder. The work has been quite remote and the teams collaborate remotely. How often should I have one to one sessions with my manager? The last time we had a one to one was during my appraisal which happened a year ago post which we never met 1:1. However, we meet once a week on a group staff meetings which is driven on a specific business agenda? Is this something healthy?
