Alex Lange is no longer CEO of broker data management firm Upstream and is now heading up new luxury real estate network Forbes Global Properties. Lange had been UpstreamRE’s president and CEO since June 1, 2016. In February 2019, the company announced that it had selected real estate data and analytics firm CoreLogic as the new vendor of its long-in-development data management platform, which aims to provide a centralized point of entry for broker data. National Association of Realtors (NAR) subsidiary Realtors Property Resource (RPR) was previously the vendor for the beleaguered Upstream, which first launched in May 2018, after two years of delays and turned out to be defective. NAR had spent $13 million of its members’ dues over three years on the project, before cutting ties in December 2018.
