In a recent analysis of venture capital returns for companies based on programming language, for the top 50 Y Combinator companies at least as of 2019, Ruby is #1, and C# is just not in the list.

I have no affiliation with Y Combinator itself or the author of the post.

The particular analysis is pretty skewed in its own way, so you can take it with a pinch of salt.

As a general rule, programming languages have ecosystems and communities, and if you pick a language where quickly delivering high-value features to users/customers is part of the community, it helps your startup; you'll probably meet founders and get business advice if you go to a Ruby meetup, but less so at a C# one.

It's not the whole picture, since it doesn't speak to the technical part of your question.

It’s a shame YC no longer lists the top companies by valuation like they did at https://web.archive.org/web/20240305133714/http://www.ycombi.... It made research like Charlie Reese’s much easier.

There’s still a list at https://www.ycombinator.com/topcompanies, but it doesn’t show valuation and can only be sorted alphabetically or by batch.

https://yclist.com/ also doesn’t seem updated.
