Pros

An elegant, disruptive product with a compelling mission and strong delivery. Very smart, motivated, and passionate employee base.

Cons

I feel like I'm watching Death of a SaaS salesman play out right before my eyes. We have an amazing product, an amazing opportunity...lots of pipeline...yet it's nearly impossible to make real money. Why? Because commission rates are at the absolute bottom of the market. If you've been accustomed to a typical SaaS commission rate of 10%...you will NOT find that here...not even close. At Slack, your commission rate will be at 3% or less. Yes, it's true... if you close a $1M deal, you will only get paid about $30K before taxes. It's unclear whether this is a CEO driven philosophical shift in not rewarding the revenue generators of the company or whether it's because Slack sales mgmt has come from non-enterprise sales roles at companies or channels where they have historically underpaid sales people (ie. DropBox, SFDC Commercial/SMB, LinkedIn etc)... but it's become a shock that has rippled through our sales org at the cost productivity. It's demoralizing, distracting, and disappointing, especially for the newer sales hires who were misled to believe they'd be able to make real money.

Amazing product but starting to get a little political

Pros

Slack is a high-velocity, awesomely creative, friendly place to work, and one of the best jobs I've had. Truly inspired by the dedication to the product and proud to say I'm an employee. I really enjoy: great engineering talent, well-reasoned decisions, a multitude of perks and good balance of right brained thinkers. We have a lot of opportunity in front of us and we're still in the building phase of the company so there is a lot to do and learn professionally and personally.

Cons

Scaling fast is exciting, but experiencing some growing pains along the way. A key leader is being irresponsible with use of power and introducing Yahoo-like politics. I believe some teams suffer from this more than others.

External Perception Outpacing Reality

Pros

• Extremely strong, once-in-a-lifetime business. From a market perspective, there's no reason Slack can't be the next MSFT/Salesforce. MSFT presents some competition in the space, but it's Slack's market to lose. You definitely have job security here. • Compensation and perks are great. Fitness reimbursement, education, phone data, etc. You'll save a lot of money by working here. Office spaces are luxurious and thoughtfully designed. • You get to work on a product (many!) people actually use and care about • There are some truly extraordinary people working here that are a pleasure to work with and learn from. • Stewart is as "unique" and inspiring as he seems from the outside. Some other executives are the same way. • Slack is no longer a startup so it's less likely you'll need to work startup hours (e.g. 9a - 5p will swing it for most roles) • The bar for tech companies is lower than sea level, but Slack is still above it. From a total package perspective, there are few opportunities as good as this in Silicon Valley, even despite its many flaws.

Cons

• Despite Slack's diversity PR, some women and minorities still experience horrible things/sexism/lesser treatment there just like any other tech company. There's more than one case of a perpetrator not only not being punished because of incidents but being promoted. Internal surveys continually reflect the dissatisfaction from URMs and virtually nothing is done. It feels awful when the company is telling a story externally that is divorced from the realities many employees experience internally. • Senior leadership is extremely hit or miss. You're as likely to find inspiring leaders as you are to find people solely focused on building their personal brand/driving readership to their blog instead of doing any real work. • There are management chains completely devoid of accountability, where a bad manager reports to and is close with a bad manager who reports to and is close with a bad manager… This is as demoralizing for direct reports/peer managers as it sounds. • Your Slack experience is highly dependent on which department/team you're a part of e.g. someone in CE or Design is much more likely to report having a far better experience than someone in Marketing or Product, but it also varies highly from team to team within each department. Do your due diligence on the team you're joining. • The monolith of a codebase has finally caught up to product/engineering. Everyone's heard about the recent weeks' long code freeze but development velocity has indeed slowed to a snail's pace. With more and more large enterprise customers coming in, a rumored IPO, etc, it's unlikely this will turn around in any substantial way. This is extremely tough if you work in Product/Design/Engineering. • Slack's culture is "too nice" — people tend to be passive-aggressive and avoid difficult conversations/feedback. Poor performers who make it past 3-6 months are almost never managed out. The foundational values of the company like Empathy/Courtesy were well-intentioned but not fully thought out and the consequences can be felt now. • The reward for doing well is typically being driven to burnout — many high performing employees are barely making it to their 2 or 3 year marks, let alone 4 years or beyond.
