RoR is the most popular choice with Y-Combinator companies.

Its productivity is simply hard to beat.

Most of these companies are unicorns or public. https://spreecommerce.org/ruby-on-rails-most-popular-among-t...

Dropbox literally hired Guido for a while and sponsored a performance oriented fork of Python.

I doubt they can be listed as a Rails success story.

I dont think Dropbox even use Ruby. They have been a Python shop since day one?

Stripe doesn't use Rails either. That was a pretty bad article. And it is somehow from Spree.

Um, really? Why are unicorns like Shopify or Github are still using Rails if that's the norm?

The same reason Facebook uses php: that's what they started with and it's prohibitively complex, expensive and risky to change at their scale.

Shopify is not a unicorn...sorry for nitpicking. Its a publicly traded company worth 210 billion dollars. It used to be a unicorn a long time ago.

Now that I think of it, are there any major startups launched post Rails glory days? Some time around and before Rails 4.0, so 2013.

Almost all the major former startups that I could find are from 2010 or earlier.

Depends on your definition of major. For a company to become a unicorn it usually takes 7 years (not sure on the number but it keeps changing). So many companies formed in 2015,16...+ aren't there still. Looking in Linkedin for Rails jobs there are a lot, not all of them are old companies. Gitlab is a very famous name(2014) but it too IPO'ed so it's not a startup anymore.

Gitlab definitely counts ;-)
