Our mission at Chordify is to make it as easy as possible for musicians of all skill levels to learn to play their favorite music. Our apps and website are powered by a distributed Haskell back end.

  • Have no managers, no micromanagement
  • Let you choose the roles that suit you best and tasks to work on
  • Help each other out

Our work philosophy is simple: We believe in an autonomous workforce where everybody takes care of themselves and their work. We call it Chortonomy, where everyone does what they know best, and with all our skills combined we make Chordify.
