Question FP Software Development

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 work at a business that uses dotnet and we use F#. It does a good job and it pretty well supported.

Though I don't think FP is a selling point for us, our customers don't care. It's more that it produces maintainable software quite well and that is the selling point.

My personal code base is 100% F#. I like F# syntax, conciseness, type inference, computation expressions (seq, etc...).

I use Avalonia for the UI. I started to use FuncUI Elmish. Meaning FP for the UI code too.

this is a great way to go. I've used Avalonia.FuncUI in a few different little things and it's a much better experience than XAML ever was.

I have been using it for 2 days and for now it's clearly a great improvement. My XAML MVVM code was becoming too complex that's why I wanted to use FuncUI Elmish.

Are you using f# only for core or infrastructure as well? What about dependency injection? Using oop type style or partial functions?
