Pros
Exciting startup environment. Individuals have opportunities to impact business in a bigger way than they would in a larger company. Open office encourages collaboration. Free snacks and convenient office location. Opportunity to learn a ton.
Cons
Turnover is problematic both for the individuals that are cut loose and those left behind. Many positions have turned over a couple of times in the last 24 months. This not only puts people out of work but also eliminates any learnings from year to year. Many business mistakes are repeated because the staff that struggled with a business challenge last year just isn't there this year to pass on what they learned in the previous season. It's a symptom of the senior team trying to make the business work. Well intentioned but ineffective. If you land a job here be sure to have a "Plan B". You will need it.
