There are testimonials on the landing page.
This is weird, because some high-end, expensive things that are great usually lack testimonials because their buyer demographics would never care about them anyway. However, it would be nice to have them for new ML services because you don't know how good it could possible be.
Relatedly, I've never understood why some books have 4 pages of testimonials in the front. Once you get past 5 of these are you really more likely to buy the book?
