Ask HN: Small product, single founder success stories? 
I'm the single founder of Bignoggins Productions. I do sports apps for mobile devices. My apps have been pretty successful, reaching as high as #32 overall paid on iPhone and #60 overall paid on iPad. Been full time for about 9 months now. Made 75K last year, and on track for 250K+ this year. Almost all profit as my overhead is insanely low. Currently traveling the world with my wife while working on apps (our travel blog is http://www.shenventure.com). In fact, I'm writing this from an airbnb in Venice right now and headed to Milan tommorrow.
