 Read through [Who is hiring June 2015 on hn](https://news.ycombinator.com/item?id=9639001), just like I did [last month](https://writing.natwelch.com/post/127). I was even less picky than I was last month. Basically if something in the job post caught my eye (location, technology, market, name, whatever) I tried to put them here. Link to their site, their Hn post, a short summary, and where they were hiring for. People still suck at describing what they do on their website.
