Brunswick Corporation
Brunswick began with a billiard table in 1845. Today, its engines, electronics, boats and clubs form an unusually complete marine ecosystem - a bet that the future of boating belongs to whoever makes the whole experience easier.
Blue Ocean Gear
Blue Ocean Gear builds Smart Buoys - rugged, connected buoys that track the real-time location and movement of fishing and aquaculture gear deployed at sea. Using dual-band satellite and radio links feeding a cloud platform and mobile app, the company helps commercial fishers find lost gear faster, spot problems early, cut fuel-burning search time, and reduce 'ghost gear' that fouls the ocean. Founded in 2015 and based in Sausalito, California, it serves wild-capture fisheries, aquaculture farms, and research institutions from New England to the South Pacific.
Arc
Arc is a Los Angeles electric boat company building battery-powered watercraft from the ground up - software, motors, battery packs and hulls - rather than retrofitting gas boats. Founded in 2021 by veterans of SpaceX, Rivian and Tesla, Arc started with the high-end Arc One, found its commercial footing with the Arc Sport electric wake boat and the Arc Coast center console, and is now extending its propulsion stack into commercial and defense vessels including electric and hybrid tugboats. The pitch: quiet, fume-free, low-maintenance boats with the torque and software experience of an EV.
Apeiron Labs
Apeiron Labs is a Cambridge, Massachusetts deep-tech company building the Tensor platform - large, low-cost networks of small autonomous underwater vehicles that persistently measure the upper 400 meters of the ocean. By making subsurface ocean data cheap and continuous instead of episodic and expensive, Apeiron sells real-time ocean intelligence as a service to defense, climate, offshore energy, aquaculture, and maritime customers. The company raised a $9.5M Series A in February 2026 and says it has already cut the cost of ocean data roughly 100-fold, with a goal of 1,000-fold.
