I would counter that it was probably their startup-oriented fintech focus and execution that led to their success. I love good tech culture as much as the next HNer but I've seen companies with great tech die because of bad biz focus.

I might further argue that the startup-y fintech culture led to good tech culture. The fact that they didn't start as a bank (as opposed to say SVB) means that they didn't have to be as conservative, or integrate with some horrific ancient tech stack.

I'm pleased they've had such success with Haskell, but much like Jane Street and OCAML, I think the language choice is almost accidental*, as much as the companies would like you to believe otherwise.

I would like to know however what they're doing for front-end. I would guess that all of this Haskell is back-end only.

*EDIT by "accidental" I mean to the business side. Jane St had some good trades, Mercury had great focus and execution. They also have some good tech :)
