TrendMD provides article recommendations for doctors. They partner with scientific publishers such Elsevier and Oxford University Press and have them add a line of their JavaScript code to their journal websites so that they can show 10 similar article links at the bottom of each page. Their mission is to accelerate the rate at which humanity's knowledge advances, by matching readers with the right articles. They serve 500 million recommendations to more than 60 million readers per month and are nearing profitability after recently graduating from Y Combinator -- the startup accelerator that incubated Reddit, Dropbox, and Airbnb.
