Unity is all about sharing, but some of us like to share a little more than others.

Our in-house evangelists are a crack team of tireless advocates and educators who make it their mission to connect with the Unity community all over the world, spreading the word and spreading the love. You can find us at trade shows, user group meetings, game jams, customer offices, and even your living room if you ask nicely enough.
