This January, I launched Read Across The Aisle [1] as a Kickstarter and we pulled in 120% of our goal. Because this is software, there is no marginal cost of manufacturing — so we're basically profitable already. I think we got lucky with the timing, which led to a lot of free press. Just today we got a mention in a front-page article in the New York Times [2]. We'll build for Android and Chrome (desktop) next. Might raise money to do so, or might bootstrap.
