Mat Gundell is a Brooklyn and Manhattan real estate agent who has closed more than 800 transactions and over $1 billion in sales since becoming a Founding Agent at Compass in 2013. He is best known for his work in Williamsburg, Greenpoint, Park Slope, and Brooklyn's brownstone neighborhoods, and for his deep expertise in new development, from sponsor sales to guiding buyers through their first new-construction purchase. He works alongside the Barak/Blackburn Team, ranked among the top 30 teams in New York City and top 250 in the nation by the Wall Street Journal / RealTrends, named to The Real Deal's top 50 new development brokers list, and recognized among the top 100 teams at Compass.

Real estate has been part of Mat's life for as long as he can remember. He grew up in a family where deals were discussed at dinner and buildings were always being walked, so joining the business felt natural. What surprised people was how he did it: in 2013 he joined Compass when it was still a startup most of the industry hadn't taken seriously. He saw early that technology would change how real estate worked and wanted to be part of it. Thirteen years and a billion dollars in sales later, that bet paid off.

For buyers, especially first-time buyers in Brooklyn, Mat is the agent who takes the time to walk you through everything. He'll explain the difference between a co-op, a condo, and a condop, help you understand board packages and financing, and show you how to put together a winning offer when there are multiple bids on a home you love. He has done this for hundreds of first-time buyers, and he's patient about it. He also personally drives clients to every showing in his own car, turning home tours into a private experience, covering Greenpoint, Park Slope, and Bed-Stuy in a single afternoon with no trains or rideshares to coordinate.

For sellers, Mat has represented owners in more than 600 transactions. After 13 years of tracking Brooklyn prices block by block, he knows how to price, prep, and market a home to get the strongest result, whether it's a Williamsburg condo, a Park Slope brownstone, or a Bed-Stuy multi-family. His listings have been featured in The New York Times (including its "What's on the Market" section), Dwell, Brownstoner, and Curbed.

New development is where Mat has made his biggest mark. He sold out all 40 units at The Diana at 435 Tompkins Avenue in Bed-Stuy and has closed over 30 transactions at The Oosten at 429 Kent Avenue on the Williamsburg waterfront. He has been deeply involved in 480 Degraw Street in Boerum Hill, The Bathhouse at 139 Huron Street and 167 and 169 Eagle Street in Greenpoint, 508 Waverly Avenue in Clinton Hill, The Isabella at 545 Washington Avenue in Prospect Heights, and 111 Montgomery Street in Crown Heights. In Williamsburg alone he has sold at 85 North 3rd Street, 172 North 10th Street, The Mill Building at 338 Berry Street, Mason Fisk at 72 Berry Street, Berry Street Lofts at 55 Berry Street, and 764 Metropolitan Avenue. He advises developers from the ground up on layouts, finishes, and pricing, and stays involved through sell-out. That sponsor-side experience is exactly why buyers hire him for new construction: offering plans, sponsor negotiations, construction quality, and unfamiliar financial structures are things he has navigated hundreds of times.

Mat has transacted across Williamsburg, Greenpoint, Park Slope, Carroll Gardens, Boerum Hill, Prospect Heights, Crown Heights, Bedford-Stuyvesant, Clinton Hill, Fort Greene, DUMBO, Brooklyn Heights, and Bushwick, as well as Manhattan's West Village, Chelsea, and Upper West Side: condos, co-ops, condops, townhouses, brownstones, single-families, and multi-families. In Park Slope his sales include 114 6th Avenue, 227 Berkeley Place, 423 3rd Street, 285 7th Street, and 434 Union Street; in Carroll Gardens, 279 Sackett Street, 160 Carroll Street, 140 Luquer Street, and 143 Summit Street; and in Greenpoint, 84 Meserole Avenue, 112 India Street, and 21 India Street.

He has also always had an eye for investments and neighborhoods on the rise. Areas he started working in years ago look very different today, and his clients have benefited from that instinct. A significant part of his practice is helping condo owners who aren't ready to sell rent out their apartments instead, managing the transition and holding onto an appreciating asset that generates income. It keeps him plugged into both the sales and rental sides of the Brooklyn market in a way agents who only sell aren't.

Mat provides a genuinely full-service experience, connecting clients with contractors, architects, designers, real estate attorneys, and movers he has worked with personally for years. Outside of work he's usually catching a Broadway show, at Barry's, or planning his next trip. He has lived in New York for over a decade and still loves it. He believes everyone deserves to love where they live, and if you ask his clients, that's what they'll tell you comes through most.
