No. Unless you get to present on stage in the Battlefield, of which only a handful are chosen, the Alley is a complete joke. Majority of the people there will be focused on the Battlefield and hardly any will frequent the Alley floor except mostly other TCD Alley folks and some random people here and there including MAYBE some off handed press folks. Of all the conferences I've attended, by far one of the worse from an attendee perspective (Launch is up there too), much less, a company with a table.
If you're hoping for exposure, this isn't it, unless again, you're in Battlefield. Just about any other tech conference would be worth your money instead, and a lot less generally speaking.
