Pros

It's hard to imagine a company with a bigger opportunity in enterprise software than Slack. We’ve paved the way within the workstream collaboration space and the market opportunity has been validated as Microsoft, Google and Cisco build competing products. I feel lucky to sell a product that is genuinely loved by our users. It’s inspiring to see how our customers embrace Slack to transform how they work. We’re fortunate to partner with some of the largest companies in the world. 

One of the reasons I joined Slack is to help build a unique team and culture, which has been remarkable to be a part of over the past two years as we continue to scale our NYC office. I’m surrounded by driven coworkers who are smart, passionate, and make it fun to come to work.

 As a member of the sales team, it’s reassuring that Slack is aligned across the board to optimize the product-market fit within large organizations – our company strategy and our investment in support roles prove that we’re doing everything we can to accelerate growth.

Cons

It can be challenging to go head to head with other tech titans and sell the value of our product when our competition is often free. However, Slack will trust you to pursue the approach that you feel will be most effective and empower you to take risks. The skills that are required to succeed at Slack will position you well for whatever you do next in your career.

Pros

Slack for me is the best of two worlds: the excitement of a true startup, but with the financial stability of a large company that comes from having hundreds of millions of investment in the bank. This provides an environment of ceaseless forward momentum and opportunity to stretch yourself. There is not only an opportunity to put your stamp on things, but a necessity, as small teams try to achieve what is normally done by groups ten times their size at other companies. In general, your leadership will give you wide latitude and trust to get the job done as you see fit. If you are ambitious about your career, Slack is an open road.

Cons

Many people feed off the energy of a startup environment. If you don't, however, and instead seek stability and predictability, Slack will probably not be the dream employer for you. As a company that has achieved more in four years than other top tier tech companies have in ten years, change is constant here. If you have come from a large company like Google or FB, learning and development will feel different than what you are used to. You will find very little structured, classroom-style learning here, but you will learn on the job through being afforded opportunities to do things you otherwise wouldn't. Some may find this a little daunting.

Pros

Smart, empathetic coworkers who share values and motivation, feeling that you're making or growing something special that's really changing the way people work together, great perks that aren't too ostentatious, friendly to working parents, older average age so you're working with grownups, tolerance and/or support for creative experimentation, big equity potential.

Cons

Fast growth that makes consistency across departments hard to maintain, need to fill positions has led to some hasty hiring of people who turn out not to work out, leadership has genuinely great intentions that in some cases seem to be a challenge to follow through on.
