Some of these are wrong: Rappi used PHP exclusively for it's first year, for instance

If you can send me a source for that (on Twitter @charlieinthe6), I'm happy to make that change!

Can we also submit it via HN? If so, my understanding is that Pagerduty is running and long-term invested in Elixir (https://www.pagerduty.com/blog/elixir-at-pagerduty/) and Podium has migrated from Ruby to Elixir as the main stack (https://medium.com/podium-engineering/two-years-of-elixir-at...). Thanks!

Edit: oops, I see now it is the initial language. Indeed PagerDuty started using Elixir only later on. Although one could argue Elixir was part of Podium in its initial growth.

Exactly - trying to capture what language they started with.

It was by no means a perfect science - was a lot of digging around on the internet for the oldest reference I could find!

You have Go listed for Twitch, but justin.tv launched in 2007 and Go didn't exist until 2009.

Great point! Will make the change now.
