Commercial real estate comps and data firm CompStak is expanding its services to include investment sales information.

The firm got its start in 2011 by crowdsourcing office leasing data and incentivizing brokers to share market details about current deals in exchange for gaining access to other lease comps. The company will now aggregate investment sales data including cap rates and net operating income, The Real Deal reports.

The platform will also compile and analyze information pulled from public records, giving users more power and knowledge when making decisions about pricing, investing and potential sales, according to TRD.

CompStak is in approximately 70 markets across the country and has raised an estimated $20M in venture capital since its inception, though most of the company's revenue comes from its enterprise offering, which clients like Wells Fargo and Carlyle Group pay an average $50K/year for to gain access to CompStak's information and data.

In May the company teamed up with Xceligent to integrate platforms to boost its competitive edge in the market. The company was founded by CEO Michael Mandel and Chief Technology Officer Vadim Belobrovka.
