Pros
I have worked in a lot of organizations (large/small, for-profit/not-for-profit, old/young...) and have managed to collect plenty of scar tissue over the years (and gray hair) throughout my career (largely in technology). As a result, I have seen a lot of leadership teams, strategies (or lack thereof), markets, visions...I have never been more excited about the future than now with Health Catalyst. That is not to say there are no challenges (see cons response). However, what I is increasingly impressive is the leadership determination to live and teach the culture. I have never had more confidence in a leadership team. Typical challenges of being a fast growing company: learning to plan AND be nimble, learning to identify new opportunities AND focus, learning to sustain a culture AND make refinements as needed, learning to help clients be successful AND develop a sustainable economic relationship, learning to find AND develop AND retain great talent.
Cons
Team members who don't really embrace the cultural values: humble, hungry, and smart. Fortunately, there are very few such team members and leadership seems determined to either help people learn the cultures or find opportunities elsewhere where the culture might fight them better.
