Scout is actually pretty good, not sure if you saw it or not.
In any event, don't take my call for research as a call not to join the party. The fact that you haven't heard of them means that none of them have quite solved the product/market fit stage and made it to ubiquity. Being intimidated or imitating them would not be the way to go, but knowing about them would probably be useful, and they have some good ideas.
(alternately, it means that most people prefer to do this in-house, and there's just not a market there. But I don't believe that, this is such boring stuff that happens on every project...)
anyways, good night and good luck
