Forbes named CoStar Group one of the “World’s Largest Public Companies” when we earned a spot on its Global 2000 list, and Fortune identified us as one of the “100 Fastest-Growing Companies.” In 2019, we earned $1.5 billion in revenue.

But we’re not all business — we have heart, too.

With the support of Founder and CEO Andy Florance, CoStar Group performs philanthropic works through our employee-led network of service chapters, CoStar Group Builds. Started in 2011 when an employee brought together colleagues who wanted to volunteer locally, CoStar Group Builds has grown into nine chapters across the US, Canada, and the UK that fulfill four major community needs:

• Environmental Sustainability

• Youth Health and Education

• Disease Research

• Homelessness and Hunger

In 2019 alone, CoStar Group Builds engaged 1,492 employees and poured 5,126 volunteer hours into the communities in which we live and work.

Our most recent initiative is a partnership with Yellow Ribbon Fund – a nonprofit organization dedicated to enhancing the lives of military families facing medical crises. CoStar Group, through our brand, provided $36,000 in funding – enough to cover one year of rent for apartments near Walter Reed National Military Medical Center. Our contribution will allow two or more families to remain intact while their injured or ill service member undergoes treatment and recovery. 

CoStar Group Builds will also provide the families with a “welcome wagon” of needed items to stock their furnished apartments – small appliances, cleaning supplies, toiletries, and other items they will need to feel at home while their service member recovers.

Get colleagues who care.

At CoStar Group, you can work for an industry-leading company with colleagues who care about others and improving our communities.

    I have been working at CoStar Group full-time (Less than a year)


    Brilliant people, great place to work, amazing views at the offices and great support from management. Everyone is so nice in all departments, and yes, there is pressure on metrics, but at the end of the day, it helps grow you as a person, and realise what you are actually capable off, plus you are very well supported, my line manager (SG) does an amazing job of making time for you, when he himself is so short on time, he is willing to go the extra 20 miles to ensure that the whole team is well supported, personally do not know how he does it, but that's why he is the regional director, because he makes time for all. I can only see this company moving from strength to strength because of the team, the people in charge are visionaries and they are all the right people that are going to move this company forward.


    As long as you work hard, there are no cons.

    Advice to Management

    Keep it up, you guys are the reason it's growing at an astronomical rate. The CEO Andrew C. Florance is still very much involved in the vision, and invests in technology and the team to make sure that we are always giving the very best product and service to all our clients, my advice is to keep doing what you are doing!
