Sourcing.io is a simple tool for sourcing talented software engineers. We've crawled sites like GitHub and Stack Overflow to build an index of people and then ranked them based on their open source contributions and notoriety on Twitter. You can search this index using lots of different filters and invite your team to connect their social accounts so you can see which engineers are in your company's extended network.Sourcing.io is newly owned and operated by Underdog.io.
