Interestingly, I've found that tools become less important the more you nail your purpose, culture, communications and processes.

For that, the Traction book would get you off to a very good start in implementing your company "Operating System".

I do understand your interest in tools though, but I spent far too long obsessing over tools in my business. Perhaps it's because I'm a software developer and I wanted to believe that tools could fix the problems, rather than facing up to the more human challenges.

Right now our 15-person business uses Notion, Slack, Google Docs, Figma Jam, Semrush and Productive. These cover all the things you mentioned.
