I’ve been consulting several founders recently on building their X persona. I won’t cover the upsides here – it’s obvious. Instead, I want to create a series of tweets explaining HOW to build a strong profile on X. Lesson 1 ↓ First, define where the founder has real authority. A useful expertise zone is specific enough to support repeated, original commentary. For example: • not “fintech,” but “stablecoin card adoption and consumer payment behavior” • not “AI,” but “how small B2B teams use AI to compress research and GTM workflows” • not “startups,” but “how solo founders build distribution before hiring a marketing team” • not “crypto,” but “how Web3 projects turn community trust into measurable activation.” Each expertise zone should answer three questions: • What does the founder know better than the average market participant? • What does the company need to be trusted for? • What conversations are already happening on X where this expertise is relevant? The best founder personas sit at the overlap of lived experience, company strategy, and active market conversation. If the founder has no clear expertise zone, the account usually becomes random. It starts reacting to whatever is trending, copying bigger accounts, and posting broad advice that could come from anyone. This makes growth much (much!) more challenging.
