Commonrise Ventures is a New Hampshire-focused real estate development and construction firm. Partnered with JH Spain Construction Services, we bring institutional expertise and in-house building capability to every project — from adaptive reuse to ground-up multifamily.
Commonrise Ventures is led by Jason Denoncourt, Managing Partner, who brings 25 years of real estate development, finance, private lending, and economic development experience across New England. Commonrise is strategically partnered with JH Spain Construction Services for full in-house construction capability — from acquisition through delivery, on any residential project, at any scale.
"We don't just develop deals.
We build alongside you."
Jason leads acquisitions, capital, and portfolio strategy for Commonrise across New Hampshire and Massachusetts. He most recently served as a private lender with Renovo Financial and First Boston Capital Partners, providing and managing short-term bridge capital to builders, developers, and investors for acquisitions, ground-up construction, and renovations throughout New England.
Earlier, Jason spent eight years with The Gutierrez Company, where he was one of four managers overseeing the firm's 4 million square feet of office space and 10 million square feet of developable land in Northeastern Massachusetts — leading development of Red Hat Software's headquarters in Westford and E Ink's headquarters in Billerica. He went on to spend three years as Congressman Seth Moulton's Economic Development Director, leading economic development across the 39 communities of Massachusetts' 6th District and spearheading the Lynn Economic Advancement Development Team alongside Governor Baker's office and Mayor Flanagan's office. He also spent five years as a small business owner through the pandemic, and began his career as a real estate advisor with CBRE New England.
