I couldn't think of a better hire for this role. InVision is just killing it right now. If you haven't heard Aarron's interview with DRT, it's worth a listen. He's very well-spoken and brings a new take on design problems, offering perspectives that I've never heard before. In my opinion, a true master.
I've heard Aarron speak at some workshops and conferences. Definitely a great pickup for Invision. Looking forward to seeing his impact on their various products and posts.
