None of the players are tied to Ruby, but the agents are often written in it (not ideal, as the usual 35MB memory footprint adds up over many servers).
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...)
