Pros

Truly agile and collaborative environment Best in Class Product, Support and Leadership Extremely positive work environment Competitor aware and customer obsessed A vital SaaS solution for your customers - not a commodity and easily differentiated Internal support is Grade A

Cons

Classic pains of a scaling SaaS company competing against legacy, well known incumbents Slack is difficult to explain - which is challenging but not impossible

Pros

1. My coworkers are very supportive 2. So much greenfield in lots of areas of the product 3. A ton of work to be done 4. You work on a product many people love 5. Company benefits are the best I've ever had 6. I've been consistently busy/working hard since I joined 7. Lots of career growth opportunities 8. Lots of grass-roots efforts to improve overall code quality 9. We work hard, and then go home. You can hear crickets (not literally) in our Slack workspace overnight. Work-life balance really exists here.

Cons

1. Lots of engineers, not enough product managers or designers to unblock engineering's work so they are sometimes a bottle neck 2. The process of assigning work to engineers is not a well-oiled machine 3. Not a lot of process in general, which leads to inefficiencies
