Which Technologies Do Startups Use? An Exploration of AngelList Data.

There's a lot of hype surrounding new programming languages, databases, and the like. I've always been curious about which technologies are actually in use, and whether great startups use different technologies than no-so-great startups.

Fortunately, AngelList offers some self-reported data about technology usage. For example, you can see that Robinhood uses Python, Django, and iOS while Secret uses Java, Go, Python, JavaScript, HTML5, CSS, iOS, and Android.

Additionally, AngelList calculates a Signal score for each startup. While it's not 100% clear what this represents, it seems to be some combination of company quality and popularity. For example, these are all of the startups in the Transportation sector, sorted by their Signal scores.
