At Demo Day 2025, Ocean Innovation Takes Center Stage
From cleaning up wastewater to detecting harmful algae blooms, the startups in BlueSwell Cohort V demonstrated how they’re tackling tough environmental challenges with blue technology at the annual Demo Day showcase.
By New England Aquarium on Friday, March 14, 2025

Recently, the fifth cohort of startups in BlueSwell—a blue technology accelerator founded by the New England Aquarium and SeaAhead—gathered for Demo Day, an annual celebration and culmination of the 20-week program.
The theme for the evening was “Blueprints for a Better Ocean,” highlighting the relationship between cutting-edge tech and environmentally responsible practices as the foundation of a thriving blue economy, and key to a healthy future for the ocean. “Each startup that you see tonight demonstrates that innovation inspired by and for our ocean is what we need right now more than ever,” said SeaAhead founder and CEO Alissa Peterson in her opening remarks.
Guest speaker Ashley Stolba, Undersecretary of Economic Foundations for the Healey-Driscoll administration, addressed Massachusetts’ recent commitment to support bluetech and climate science innovation in the state. By investing $1 billion in the industry over the next ten years—as well as helping founders “start, scale, and grow” their businesses—the administration aims to make Massachusetts a leader in ocean innovation and foster opportunities for startups like those in BlueSwell.
BlueSwell focuses on bridging the gaps between innovators, ocean experts, industry, and the venture community, leveraging SeaAhead’s bluetech domain expertise and the Aquarium’s long history of using science developed by the Anderson Cabot Center for Ocean Life to protect the ocean and marine animals. Over the course of the program, founders receive funding, mentorship, networking opportunities, and more to help them convert their startups into sustainable, profitable businesses. Demo Day gives each startup founder the chance to highlight their progress at the program’s end. Each aspiring entrepreneur shares their company pitch in front of an audience of Aquarium and SeaAhead community members, as well as potential investors, business partners, and future customers.
