The coworking franchisee operates a Venture X in 23,000 square feet across the top two floors of 110 16th St., a 1950s office building in Denver’s Upper Downtown. The building’s owner was awarded a $14 million loan in November by the Downtown Development Authority to help convert the 200,000-square-foot structure into 178 apartments. Borst said he told Sheperd for years that the building’s future as office space was uncertain. Venture X is the only office tenant remaining in the building, Borst said. Borst noted that it’s not hard to find other space downtown, where office vacancy was 38% at the end of 2025, according to real estate brokerage CBRE.
