Growing X (Twitter) as a non-technical founder - what do you post about? I will not promote

Been trying to grow my Twitter but feeling stuck. As a non-technical founder, I find it hard to know what to share - can't post coding tips or technical stuff. What do you post about if you're on the business side? Would love to see examples of non-technical founders who do this well. "I will not promote" - looks so weird to need to place it everywhere.
