Pros
Great people, a collaborative culture, and the opportunity to make a real impact from day one. A fast-paced environment with talented colleagues and plenty of room to learn and grow. Love the product and solutions. Super technical environment. start-up with one of the best efforts and investments in people and culture I ever met. I had the opportunity to be the 1st leader in the recruitment and to build a team, processes and infrastructure. The founders are great partners to work with and they care about things (some people can see that as demanding, I see that as care). they understand importance of processes and good culture.
Cons
Like every start-up the pace, demand and level of investment are high, it's not for anyone who is looking “to kill time”. You need to roll up your sleeves and get to hard work - but it will pay in the future.
