Congrats for launching! Sounds like a valuable service. I dont think you're doing a good job selling it though. The home page is too full of marketing speak. I would prefer more concrete examples of how your service aids in customer retention.
Also, im personally not a fan of stock photos. I think you'd be better off with screen shots of the product.

Looks really nice. Im on a phone and the site and demo worked really well. Congrats on launching and all the best! How long has the product been in development?
