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.
