Buy a Substack business only after audience diligence
A Substack business can mean a publication, a paid newsletter, a sponsorship asset, or software serving Substack writers. The strongest acquisition targets have transferable audience demand, recurring revenue, clear sponsor relationships, and analytics that prove engagement quality.
