Kartra

Kartra competes less with Teachable and more with a funnel-building suite, an all-in-one marketing platform where courses and memberships are one module among several covering funnels, email sequences, forms, and a built-in helpdesk for customer support. Its entry Essentials plan carries a 5% transaction fee that disappears on the higher Starter, Growth, and Professional tiers, which run up to $429 a month on annual billing.

The depth of the funnel-building and automation tools is a real advantage for a business running paid ads and complex email sequences around a course launch, at the cost of a genuinely steep learning curve compared with Podia's or Thinkific's simpler course-first design. It fits a marketer or course creator already running, or planning to run, an aggressive sales funnel with ads and automated follow-up, more than someone who just wants to host and sell a course simply.
