Blue Institute Reveals New BX6 Blue Excelerator Cohort

The Blue Institute has announced the 12 companies selected for BX6, the sixth cohort of its Blue Excelerator, a no-cost accelerator for ventures focused on ocean health, climate resilience, maritime systems, and water security. The Earth Day announcement coincides with the nonprofit’s 10th anniversary.

The new cohort, known as the “Blue Dozen,” includes companies from the United States, Canada, Germany, and Denmark working on technologies such as AI marine mammal monitoring, offshore sargassum forecasting, ropeless fishing, oil spill response, offshore robotics, aquaculture systems, and zero-emission sail freight.

The program is designed to help emerging blue economy ventures strengthen commercialization strategies, advance pilot opportunities, and connect with partners across a North Atlantic innovation network that includes organizations from across New England. Participants also gain access to more than 100 mentors and speakers with expertise spanning engineering, venture development, manufacturing, communications, and finance. The organization has served as a Connector in the U.S. Department of Energy’s American-Made Network since 2022.

Across its first five cohorts, the Blue Institute said it has supported 49 alumni companies, including 42 in climate tech-related sectors. Those alumni report an 84% survival rate and have raised more than $24 million in follow-on funding. Thirteen alumni have established a Massachusetts presence or are active pilots in MA. WithBX6, the organization said it has now accelerated 61 companies.
