BOULDER - A company that provides co-working spaces for entrepreneurs and investors has opened an office in downtown Boulder with about twice as much space as company officials expected to need.

Hub Boulder LLC opened a 10,000-square-foot office Monday on the ground floor of the Randolph Building, 1877 Broadway.

"We had originally planned to build out 5,000 square feet," said Greg Berry, managing director and co-founder of Hub Boulder, in a press statement, "but we were sold out almost immediately, well before we had even begun to build the space. The demand for collaborative space in Boulder for social impact-oriented businesses is just incredible."

Hub's facility includes space for offices, meetings and events, and can hold up to 150 people. It's part of a global network of more than 40 Hub locations on five continents dedicated to supporting social enterprise by providing resources, connections, incubation, networking and events in a flexible space where members work, connect and host their own gatherings.

Prospective members are screened to make sure their values are in line with Hub's mission.  Memberships start at $25 a month. Hub Boulder began welcoming members in May and now has 120, according to the statement.
