D.C.-based &pizza has closed a funding round with an undisclosed investment from RSE Ventures, a New York-based firm led by developer Stephen Ross of the Related Cos. and Matt Higgins, vice chairman of the Miami Dolphins.

With its new funding, the fast-casual pizza chain co-founded by Michael Lastoria in 2012 will continue its expansion beyond the 23 restaurants it currently operates in the District, Maryland, Virginia, Pennsylvania and New York. In 2018, &pizza is expected to debut up to six new restaurants in New York alone, and the chain anticipates launching in Miami and Boston as well.
