This is really interesting and I'm sure it has many useful applications - what I am most impressed by is the popovers in your dashboard, which show SDK examples. This is a brilliant UI idea (executed with great polish) and is the first time I'm seeing it.

Unfortunately I'm not a potential customer and don't have useful feedback on the market landscape - all I can add is that I really love your design. Also it seems like you all launched the new landing page while I was typing this comment a little past midnight, so kudos on the work ethic as well.
