To determine companies that provide commercial real estate databases, analytics, and other data similar to CoStar our initial search was to look for CoStar's competitors in press releases, market reports and company profiling databases such as Crunchbase,, Zoominfo, etc. We came across an article from Bisnow on "CRE Data Companies Cautiously Emerges To Challenge CoStar." This article mentioned startups like VTS, Reonomy, and CompStak that were launching new services to compete with CoStar. Then, the research team uncovered another article from Renx.CA about CoStar's presence in Canada. As quoted in the article: "The Canadian market is very fragmented....[t]here are a lot of little boutique data providers, but not a one-stop-shop that will provide all the services with a very advanced technology platform". Considering this, we understood that there are very few companies in the Canadian market that offered true commercial real estate databases, analytics, and other data similar to CoStar. We then turned our focus to the US market and continued checking for CoStar competitors. In several sources, we found that Reonomy and CompStak were mentioned as valid competitors. We then individually reviewed each company to understand whether it provided database and market intelligence services for real estate in a similar fashion as CoStar. We found that Reonomy and CompStak provided market intelligence and database services for real estate companies and hence we have listed them in our findings.
