New York-based, technology-driven real estate company Compass is set to open an office in downtown Boston.

The office will be located at 126 Newbury St., inhabiting three floors and 21,000 square feet of space.

Established in 2013 by Robert Reffkin, former chief of staff to the president and COO of Goldman Sachs, Compass holds over $1 billion in listings and $2.5 billion in new development funding.

“Boston’s strong real estate market provides a unique opportunity for us to showcase our innovative technology, which brings intelligence to the home purchase and sale processes,” Reffkin said in a statement. “Boston’s real estate leaders and consumers alike will find that working with our mobile-first technology eliminates many obstacles, resulting in a faster, easier and more efficient home-buying experience.”

Jeannemarie Conley will oversee the Boston office as managing director.
