What they are
Substack
Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
Kajabi
Kajabi is an integrated platform where creators build and sell online courses, memberships, coaching programs, and digital downloads without stitching together separate tools. It combines a website builder, email marketing, payment processing, and community features under one subscription. Coaches, course creators, and consultants make up the core user base. The convenience comes at a premium price that may be hard to justify for creators just starting out.
