I really wish this list was longer.

This list actually is longer: https://github.com/erkmos/haskell-companies

Also, it might be a better list if the companies mainly used haskell. Having Meta or Microsoft doesn't mean all that much as they probably use every language under the sun somewhere.

The size of the list is determined by how much time the author decided to spend doing it.
