Great and useful column.
I have a course (a long one - 12 weeks, mindfulness and brain training) on Thinkific. It's a great platform, but I'm about to put together several brief courses (mindful piano improvisation, lucid dreams, and a few more) that I think might be more suitable for another platform. I was thinking of Udemy, and actually, the courses would be more appropriate outside the "Udemy for Business" program, so it sounds like that might work.
I see you wrote this some time back, so i was wondering if you still have the same perspective on selling courses (not the same ones) on several platforms simultaneously.
I'll just add that Thinkific only gives the choice of paying through PayPal - while that is extremely popular, there are some students who refuse to use it. Udemy offers that plus most credit cards. It also allows people to search Udemy for courses they want; an option that is not available on Thinkific.
Thanks again for a very helpful column.
