Seems like it's a transaction brokerage service. I don't think the problem is the finance jargon, but more the fact the site doesn't show anything of substance (apart from the unexplained blockchain search widget). It doesn't seem you can actually try this service out yet - or maybe you can, but you have to talk to their sales team first. I'm not sure how it's at the top spot on HN's front page though, so I might have missed something. Maybe upvoters have a piece of context that we don't.
