Haskell in production in 2017 at a startup? Yup
summary
FretLink runs Haskell in production for core services (three services so far, adding about one new service per month) and deploys reproducible binaries with Stack LTS builds on Clever. They use Servant to describe APIs and generate client/server code and docs, Warp for HTTP serving with Prometheus metrics, QuickCheck and unit tests for validation, and integrate Google Admin APIs for mail migration and Google Maps for routing.
