Cool! This looks like go/ links, the internal URL shortener that Google uses and which a lot of other tech companies subsequently adopted (I wrote about it here: http://blog.goatcodes.com/2018/04/18/go-origin)
Full disclaimer: I built goatcodes.com to be a hosted version of go/ links, short links for teams. It serves a similar purpose to Gurn, albeit in a slightly different way. Think bit.ly, but you have to log in before the redirect.
