    Innovation: Nuance is like a $2-billion start-up. There are so many things we are doing for the first time, but the scale is huge and the machinery is complex.

    We are a matrix organization: It is challenging but very rewarding to build collaborations with stakeholders that are halfway around the world.

    Impact: It boggles the mind to think that such a simple thing like software can not only change lives, but actually save lives. And finally, to paraphrase a quote from an unknown source: You have to be a little bit crazy to work at Nuance, but you have to be completely crazy to work anywhere else.
