Running a startup on Haskell

At MailRank, we’ve built our server technology stack using the Haskell programming language. Haskell gives us a tremendously different environment from Python, PHP, and so on, so why have we made such an esoteric choice?

In this talk, we’ll talk about the reasons for our choice, and some of the advantages and disadvantages we’ve observed along the way. In particular, we’ll survey the Haskell-based technologies that make it a great fit for companies working in tight constraints, who must produce excellent products quickly.
