A tech firm is taking 32,000 square feet at Stellar Management and the Rockpoint Group’s massive office and retail project in Soho. Marketing consulting firm DoubleVerify inked a five-year lease at One Soho Square, the Wall Street Journal reported. Stellar and Rockpoint are developing the 768,000-square foot project, by combining two pre-war buildings at 223 Spring Street and 161 Sixth Avenue. DoubleVerify’s new space will fittingly be double its current headquarters at 575 Eighth Avenue.
