Anyone with experience using Persado?

Hey Braze power users, 

I was watching a webinar last week that Snowflake was hosting that revolved around using the Persado AI tool with Braze. It peaked my interest which lead me going down the rabbit hole of learning more about Persado's product.

While my initial research has got pretty excited about the capabilities I wanted to ask and see if any other Braze users have experience with it. Do the motivation AI and dynamic motivation products actually deliver ROI for your business? Does it speed up AB testing with the experimental design framework?
