You're off by probably an order of magnitude. You can absolutely scale this organization to 100+ engineers. I've worked at a company with ~30 Haskell developers and I was involved in hiring most of them without lowering our hiring bar. If we really needed more it would have been quite easy to lower the bar a little and increase the numbers significantly. Here's another example of a company that has a large Haskell team: https://iohk.io/en/team/#team=development https://iohk.io/en/team/#team=development Now if you needed to hire 1000 developers, then you'd have more of a problem, and perhaps Haskell wouldn't be the right approach. But in my experience, Haskell engineers get a multiplier effect over the average non-Haskell engineer because the code is more concise and the average engineer skill is higher. I don't know what the multiplier is, but it's definitely non-zero and positive. This not only pays the obvious direct benefits, but also reduces the communication overhead of your team and the number of managers you need to hire.
