Hyper growth company with great people

Pros

I have worked at many start ups and this is the most exciting, dynamic, and professional start up environment I've worked in. The people here are mature, bright, empathetic, and collaborative. The company is growing unbelievably fast, but everyone is still very helpful and team oriented. There is a big focus on diversity and inclusion, which is so important and appreciated. You can really feel how big of an opportunity there is here and for those who like building something great, there will be a ton of room for growth.

Cons

This is a high growth environment so employees needs to be ok with being flexible and creating the play book as we create a fairly new market. This is not a con, just a note on who will succeed here.

Pros

Open culture, solid values, strong leadership, Stewart, and plenty of challenging work to support an amazing opportunity.

Cons

Being in a hyper growth business and company can lead to some stress at times, but overall this is how people learn and grow their careers. Much fast career arc here than working at a huge Tech company.
