pHathom Technologies, founded in 2024, is a Canadian climate-tech company building a platform that captures biogenic CO₂ from coastal bioenergy and industrial plants and converts it into stable dissolved inorganic carbon that naturally occurs in seawater. The treated water is then returned under closely matched conditions, eliminating the need for pipelines, long-distance transport, or geological injection while operating within current industrial footprints. The process is engineered for high standards of scientific measurement and third-party verification, aiming to deliver durable and auditable carbon removal credits. pHathom is piloting its technology through the $16 million Bioenergy Carbon Capture and Marine Storage Project backed by Canada’s Ocean Supercluster. Market validation includes selection for Frontier’s advanced purchase of carbon-removal credits and recognition as Foresight’s 2025 Atlantic Canada Startup of the Year. Financially, the company has secured more than $12 million in committed capital, including a recently closed $4 million seed equity round. The fresh funds will accelerate pilot deployments, expand scientific monitoring, and support regulatory engagement for broader commercialization.

Founded in 2023 in Rhode Island by maritime practitioners and defense engineers, Vatn Systems is building scalable fleets of autonomous underwater vehicles for the U.S. military, allied governments, and civilian customers. Its flagship platforms, the Skelmir S6 and Skelmir S12, combine a plug-and-play payload architecture with INStinct, the company’s proprietary inertial navigation system that provides GPS-denied guidance at a fraction of traditional costs. The vehicles support distributed sensing, ISR, mine countermeasures, electronic warfare, and other emerging undersea missions, and can be re-configured for offshore energy, port security, and environmental monitoring in days rather than months. Throughout 2025 the company delivered AUVs to U.S. government customers, ran successful open-water demonstrations, and ramped production capacity to meet growing demand. Vatn positions itself as a future “underwater defense prime” by offering attritable, mass-deployable systems that align with shifting naval doctrines. Commercially, the same low-cost autonomy unlocks persistent coastal infrastructure monitoring and scientific research opportunities. The recent capital infusion is intended to accelerate production scaling and broaden mission profiles for both defense and civilian markets.

SuperGround Oy is a Finnish food-technology company with a patented processing technology that transforms undervalued fish and poultry side streams into high-protein ingredients for consumer products such as nuggets, patties and burgers. Its approach is designed to help food producers lower costs, reduce waste and increase protein content while maintaining taste and scalability. The company secured an additional €1.15M extension, bringing recent funding to €3.65M, a signal of investor confidence in a tougher FoodTech funding environment. The extension round was led by CHECK24 Impact (Germany) and Propeller Ventures (US), following earlier backing from Hatch Blue Revolution Fund. SuperGround plans to use the fresh capital to accelerate commercialization, beginning with a partnership with Sweden’s Ocean Next AB. Production and launch of sustainable seafood products across the Nordics will be driven via Ocean Next and Korshags Food AB, with production in Falkenberg.

Founded in 2024 and headquartered in Sunnyvale, California, Nexxa.ai develops Nitro, a multi-agent orchestration platform that layers on top of legacy industrial engineering software to automate complex, non-standard workflows. The system allows Forward Deployed Engineers to embed compliant, explainable AI into rail, construction, manufacturing and other critical-infrastructure processes, delivering measurable ROI within weeks. Current enterprise users include Siemens, Matikon and additional undisclosed customers, and the product is also distributed via the Siemens Xcelerator Marketplace. Management plans to leverage its new capital to scale revenue 10× during 2026 by expanding across core heavy-industry sectors. Nexxa.ai positions its technology as a catalyst for modernizing America’s industrial backbone without ripping out existing systems. The company has secured $14 million in total funding to date, comprised of a pre-seed and the latest seed round, to accelerate product development and go-to-market execution.

Vema Hydrogen develops Stimulated Geologic Hydrogen (SGH) technology that produces hydrogen by injecting a catalyst-bearing brine into shallow geological formations where it reacts with iron-bearing minerals. The hydrogen is extracted for use in electricity generation, heat, and production of green chemicals and fuels. The company says SGH enables production in strategically selected locations, reducing exploration uncertainty, logistical challenges, and costs while allowing precise control over gas composition and flow rates. Vema plans to use the funds to develop the first clusters of full-scale SGH pilot wells in North America. The company was founded by Florian Osselin and Pierre Levin and was created at the venture studio Marble. Vema is based in Wilmington, DE.
