Analyse your fitInvestment thesis
Maine Angels is a membership-based network of accredited investors founded in 2003 that invests in and mentors early-stage companies, with a primary emphasis on Maine businesses and a broader reach across New England. The group looks for scalable businesses with differentiated products, capable management teams, achievable exit strategies, and sufficient addressable markets to generate high returns. They prefer East Coast and New England deals within range of a site visit, and companies outside Maine must be engaged with a lead investment organization prior to applying. Through their Dirigo sidecar funds, Maine Angels pools capital from individual investors and Maine institutions to stimulate the state's startup ecosystem, targeting 75% Maine-based companies, 40% owned or managed by women or historically underrepresented minorities, and 25% in priority sectors including Cleantech, Aquaculture/Blue Economy, Agriculture/Forestry, and Life Sciences. The network syndicates closely with state agencies (Maine Technology Institute, Maine Venture Fund) and regional angel groups (eCoast Angels, Golden Seeds, HubAngels, LaunchPad Venture Group, TiE Angels) to expand deal flow and follow-on support.
Notable quotes
“They invested in multiple rounds and served on the board of my Maine solar start-up, Pika Energy; so after Pika's successful exit, I joined Maine Angels because I was eager to give back. We learn from each other, and our wide range of work backgrounds make our investment decisions and our advice to start-ups exponentially stronger.”
“Mary Ellen is passionate about investing in Maine businesses, especially those that are led by women and focused on the environment.”
“We invest for financial return, but also to make a difference in Maine and the world, by growing start-up companies, creating jobs, and offering opportunity.”
