Although I am not a CEO (but a marketer), I have a similar setup using Acme. I do all my note-taking inside Acme and have my plumbing logic set up so that all documents/JIRA issues/etc. are a single click away.
I think there is something to be said about using a few (if not one) text-centric tool to get stuff done: it's much lower on your cognitive load and wears you out less.
