The page doesn’t list the year the startups were founded. I wonder if you’d see a good correlation to the founding year.

More startups on the list use Ruby than any other language, and it accounts for over fifty percent of the valuation. It was very popular with startups ten, twelve years ago, but may since have slipped?

On the other hand among younger companions es one might expect to see more Go, Node and maybe Rust?

Still, an interesting analysis.

If you're talking about survivorship bias, I can well believe it.

Ruby is still popular with startups, and there's no falloff in Rails usage, if the gem download graph is anything to go by.

This is excellent, thanks for sharing. Anyone know if something similar exists for JS frameworks (React,Ember,Angular,Backbone, etc)? Would be great to see their popularity over time.

I’m guessing maybe not having a single central repository like Gems will prevent this data from being so easily accessible.

what spiked the graph in November 2012?

[coldtea]

I'm not sure how they came with that projection at the end, despite the fall shown...

[inopinatus]

Assuming you're looking at the chart in the other comment, it's not a projection. The chart contains two separate graphs in overlay, and they are both of absolute numbers. Red dots are total all-time downloads, grey bars are a four-week histogram, and both show continued growth.

The author added a note under the main table about that, which goes in the direction of what you're saying:

> Note: Ruby and ruby on rails was a popular choice for YC startups around 2010 - 2012. Anecdotally, ~40% of YC startups used ruby during its peak popularity.

Yeah, Ruby and specifically Ruby-on-Rails was (and still) is very popular in SV startups. Only one mention of Elixir, I'd expect this to change in the future as Phoenix replaces Rails as the easiest framework to build MVPs.

I know that PagerDuty also uses Elixir for some of their backend services. See https://www.pagerduty.com/blog/elixir-at-pagerduty/

[wronghorse]

I'm curious about this too. I'm working on collecting that data for these companies. Hopefully that sheds more insight into this.

Yeah, I'm guessing that more recent startups will have much less Ruby usage.
