That was on you though, and by the sounds of it you realized that and fixed it. When you're a C-level you're expected to use your autonomy and agency to say no to things, and if people need you to be there (eg strategy meetings that need tech input) then they should have to work to your priorities. No one above senior dev level has too many meetings. The issue is always that they say yes to all the meetings they're invited to. Realizing that you're allowed to say no is a critical part of leadership. Possibly the most important part...
