Pros

Really good group of people working on some very challenging problems. I high level of humility considering the pedigree of the talent, very low-ego environment. Great opportunity to make an impact and get a start in an emerging industry with tremendous growth potential. The company is well led and has successfully raised capital to support the work. I've learned more here in the past few years than anywhere in my career.

Cons

It's not easy. The work is hard. There is always more to learn. It takes being comfortable with not knowing things and often not having time to do everything to the level you might like.
