Pros
friendly environment with young professionals, you get free lunch (and some people get free coffee, free snacks and free face masks) and flexible hours.
exposure to big topics
Cons
Too little experience: most people are too junior and some overrate themselves.
No clear picture of strategy, just hope to randomly hit the target
Yes-man culture: although being proactive and challenging the mainstream opinion is encouraged, most people prefer to align with the founder and never propose or expose their opinion
Endless internal meetings with no clear target, sometimes transformed into empty sermons
