Pros

Best products in the industry, no real competitor, plenty of opportunity to grow with the company. Great office space and good benefits. You can make some good money if you can make it through the ramp up and survive the dog eat dog culture. Also great people in the operation of the beast. But once you get into senior management good luck.

Cons

To say people are treated poorly is an understatement. CoStar claims to care about their people and they say the right things. But man, it can't be further from the truth. Focusing on sales, it is a grind. Monthly quotas change all the time, the comp plan punishes long time performers and changes every year, no merit based pay increases. The new EVP of sales has zero clue about what is going on yet keeps messing up a great business while pushing out great leaders across the country. The accelerated departure of tenured AEs and managers is very scary, but they don't care. Just look at the departure of the officers of the company, only one of the remaining executive leaders has more than 5 years with the company. Turnover is high across the board and management either does not listen or just does not care. Even when long time performers give up and leave, there is zero reaction. It is sad to see, but the chaos continues. I could go on but I won't, you get the picture. I finally quit and it was the best decision I have made in my career.

CoStar Group Response
10y
CoStar Group is growing rapidly and continues to be a great success, spurring exciting new opportunities through changes in leadership and acquisitions of other companies. These changes can take a toll on an organization, and their effects do take some time to adjust to adequately meet the needs of both clients and employees. CoStar Group has done extremely well in sales following the launch of new products this year, with its highest sales month ever in June this year – our executive leadership plays a big part in facilitating and creating opportunities for salespeople to succeed at the level they have so far. We listened to employee feedback regarding merit base pay increases, which is why we have implemented a performance review and merit base pay increase system for the 2015 calendar year, which has been communicated to all members of Sales on multiple occasions so they know what to expect when the new performance review process rolls out following the new year. I’m sorry you made the decision to leave prior to us being able to implement this. We are concerned about turnover in Sales, and are listening to our employees through opportunities for feedback including exit interviews, our annual CEO for the Day event and reviews like yours to look at what steps to take to improve organizational effectiveness and employee engagement. From that we have established and continue to work on a clear career path for salespeople as well as development opportunities to prepare them for promotion and increased success in their current roles. Regarding the senior management team your reporting of the number of executives with more than 5 years’ tenure with CoStar is not accurate. The majority of the CEO’s direct reports and the next level down of their direct reports have been with CoStar at least 3 years, and in many cases 10 years or more.

Pros

Unlimited catering budget for clients. Discounted stock purchases. Good health insurance.

Cons

Leadership Built on Fear, Not Respect The founder-led culture is rigid and top-down to a fault. Major decisions are made without input from those in the field, and the tone is more authoritarian than collaborative. Leadership discourages open dialogue, and mid-level managers function more like enforcers than mentors. Feedback goes into a black hole. They don't care what you think. If you don't like it, you can leave. Micromanagement at a Paranoid Level Every client interaction is monitored. Nearly all meetings are followed by client surveys. It may be positioned as quality assurance, but it feels like surveillance. Reps operate under constant scrutiny, which creates a culture of fear rather than trust. Impossible Performance Metrics Monday: Full day of in-office cold calling. Every dial recorded and tracked. Tues–Fri: 3.5 field meetings per day (50+ per month, 70% in-person). Combine that with customer support duties, internal admin, and mandatory CRM inputs — and you have a job designed for burnout. These metrics are not just aggressive — they’re structurally unsustainable. As a result, people resort to manipulating CRM entries to survive. Middle management often turns a blind eye as long as the numbers look good on paper for the execs looking at raw data. Favoritism Over Fairness The most strategic accounts and renewals consistently land with a select group. New hires and less-favored reps are left to fight over what’s left. While favoritism exists in many sales orgs, it’s particularly blatant here. No Team Environment Without defined territories, reps are incentivized to compete against — rather than support — each other. Sharing leads or best practices only benefits someone else at your expense. Collaboration is virtually nonexistent. Commission Structure is a Morale Killer You don’t just sell; you manage accounts too. Your commission is based on a 3-month rolling average. Cancellations, downgrades, or customer churn — all normal in business — are clawed back against your earnings. Example: Earn $2K in commission, lose $4K to cancellations = $0 payout, with a negative balance dragging down future checks. This creates a recurring cycle of starting each month in the red — a demoralizing reality for even the most capable sales professionals. 🧩 Clunky Internal CRM The company uses its own CRM, which is dated, unintuitive, and not designed to help you sell — only to monitor your activity. So it's a hindrance to your success rather than a tool to help increase your efficiency. Final Thought: If you’re contemplating CoStar, read all the reviews — not just the curated ones. I dismissed the warnings. I wish I hadn’t. Only good thing that I took from working there was that, even with all it's imperfections, I so very much appreciate my new company. My worst day here pales in comparison to an average day at CS.

Pros

The company has potential, with some strong teams and good managers, but the overall culture is unprofessional. There are distractions in the office, including unprofessional behavior from some employees, which affects productivity. While some teams are well-managed, others are not. If you get a bad impression from a manager during the hiring process, it may be best to wait for a better opportunity within the company. Job security is a significant concern. The company tends to over-hire and then downsize unpredictably, often using AI or budget cuts as a justification. Employees hired for critical projects may find themselves let go once major milestones are completed. Favoritism can also play a role in retention decisions rather than performance or skills.

Cons

If issues arise, be cautious about escalating them, as concerns are not always handled constructively. Some employees have reported being sidelined or placed on performance plans instead of having their concerns addressed. Additionally, there is a noticeable trend of hiring more junior employees, possibly as a cost-saving measure. Workplace relationships can sometimes blur professional boundaries, so it's best to stay focused on work and avoid unnecessary office politics. Overall, this role may be beneficial as a short-term learning experience, but long-term stability should not be expected. Approach the opportunity as a stepping stone rather than a secure career path.
