Kajabi

Kajabi sells knowledge: courses, coaching, memberships and the site that presents them. It is a real builder rather than a wrapper — pages, a blog and scheduling all live in the same product as the checkout, so an expert running a teaching business does not have to connect four services and keep them in step.

Scheduling is included rather than being a third-party embed, which is unusual in this group and matters to anyone selling their time.

The cost is the difficulty here, in two ways. Its published rate at checkout is considerably higher than the figure widely repeated in third-party comparison tables, so a reader arriving from one of those will be surprised. And no annual rate could be established at all — the signup route for it returned nothing readable — so the only number that can honestly be quoted is a monthly one. Below the top tier the account is limited to a single website, which for anyone running more than one venture is a harder constraint than it sounds.
