The practice of crowdfunding real estate is spreading to North America, specifically New York, where the developer Urban Muse is hoping to offer a slice of a Brooklyn Bridge Park project to the public.

Real estate upstarts like Fundrise, Realty Mogul and Prodigy Network are transforming the way real estate projects are built and who profits from them, allowing the public to invest in an asset class that has traditionally been exclusive to wealthy investors and private equity firms.

“It’s a very simple concept,” said Daniel Miller, co-founder of Fundrise. “You should be able to invest in your neighborhood.”
