fsharp-companies VS equinox

I've used F# across 3 companies now, only one of which actually advertised that they used F# (as opposed to .NET or C#). Two of them on this list: https://github.com/fsprojects/fsharp-companies

I’ll tell you as someone who learned programming at 12 from library books that it wouldn’t have the effect they think it does. It’s a bit shocking that someone with a professorship has such a loose grasp on things, but F# is not exactly Pyret. There are real companies with actual budgets using F# https://github.com/fsprojects/fsharp-companies

There’s a list of companies that use F# and Microsoft is one of them. Also there are testimonials from Microsoft employees and it looks like it has application in analytical/machine learning scenarios.

Here are a few: https://github.com/Kavignon/fsharp-companies

Adding your company to this list could be also some possible gain.

F# works really well with event-driven architectures. Event sourcing and MVU/Elmish both work well with immutable data (you can't change an event after it's happened!). Discriminated unions are fantastic, and F# event sourcing/MVU libraries make liberal usage of them. Elmish is a frontend agnostic MVU library that has WPF/Javascript/WebAssembly implementations. On the event sourcing side there's Akka (though this is more actor model) and Equinox whose maintainer is incredibly friendly.
