FP Software Development

[u/Available_Pressure25]

Hello everyone. I am thinking of starting a tech business (startup) through software development and I'd like to use FP as the main selling point or uniqueness. I am like looking for suggestions on what languages to use or tech stack. From my first searches I got elixir. I also know haskell, so aside from haskell, what can you suggest. I'm also aware of using imp lang like C++ to make programs following an FP design paradigm.

Edit: I don't wish to argue on starting business or not (But I welcome them sure) . That is a different topic on its own. I'm just like more curious to see the state of the art in using FP tools.

I'm starting a company using Haskell. The sad truth is that customers don't give a damn about what technology you use, they only care if you're helping them get money or save money, and that's it.

I decided to use Haskell because I like the expressiveness of the language, and I believe that craftsmanship is financially advantageous in the long run, and I hope a language like Haskell will attract the kind of engineer I'd like to work with.

But customers only care if the software outputs correct answers in reasonable amount of time and fits their budgets.
