That would be an interesting question to answer. I know of a few rapidly growing companies using Haskell that compete directly with non-Haskell companies. We'll have to see how things play out over the next few years but that might provide some data points.

Can you name them?

CircuitHub (a company I co-founded) and Habito (UK mortgage broker) stand out in my head as startups (in the PG sense of the word http://www.paulgraham.com/growth.html) that use primarily Haskell and have direct startup competition using more conventional stacks.

We come across tons of others, I keep meaning to write down a list.
