So nothing on here actually exists with any code? https://topagree.com/

Saying it integrates with those other services is a lie?

I think this is a silly.

It sounds like 'an ideas guy' built a landing page quickly, and collected some email address from that fake try-now page. And is now trying to convince a developer somewhere ("the CTO") that is a good idea and worth building for them.

They are not your cofounder/CTO if they need convincing like this.
