Why would Y-combinator alumni have to comply with any government imposed rules? I hate to sound like a broken record but check my comments or history of PG companies he founded. AirBnB co-founders were or still are on FBI top spammer list that used tax money to spam people to high heaven.

As of the product, I join vast majority that says stay away. My personal thing is that after reading one of their interview where they were inviting people to clinical study, I send them long detailed email covering my willingness to participate and even pay all the cost from my own pocket. My email got ignored and I never got response. For that reason alone, I would stay away from something you have to pay for, because their customer support sucks from the get go.
