After reading your comment, I was curious and looked up the site, and was expecting amature hour, but I think you're being too critical. The website looks well put together and communicated the product idea just fine. It's actually a very interesting idea that I think has real market demand if it actually works and produces better results than manually segmenting users (what all the other products do right now). That being said, I think it is very non-trivial to make a general recommendation engine that will work well for a variety of different apps and goals that isn't overly complicated. These things tend to sound good in theory, but fall apart in the details of practice. #1. How do you know? Did you contact them? Obviously it's not open to the public as self-serve right now. #2. I only glanced at the site, and didn't spot any. I'm sure they're there tho. #3. They're demonstrating why you should care about push notifications. I'm sure they'll replace with specific case studies when they get some. #4. I'm sure they've only begun to explore pricing at this early stage, but it seems reasonable to me. It's actually almost identical pricing per user compared to mixpanel, a YC company with a product in a similar space, at $0.002.
