Hydraloop
Hydraloop is a Dutch water technology company that makes compact, in-home and in-building water recycling systems. Its certified, chemical-free devices collect and clean up to 85% of a household's water - from showers, baths, washing machines and air-conditioning condensation - and return it for toilet flushing, laundry, garden irrigation and pool top-up, cutting fresh water use and sewage output by up to 45%. Founded in 2015 by Arthur Valkieser and Sabine Stuiver, the company won CES 2020's 'Best of the Best' award and a 2022 UN WIPO Global Award, and sells decentralized greywater systems to homeowners, developers and the hospitality sector worldwide.
Remora
Remora is a Detroit-area climate-tech company that bolts carbon capture onto the things already burning fuel - semi-trucks and freight locomotives - instead of building giant plants to pull CO2 back out of the sky. Its zero-backpressure device threads exhaust through proprietary adsorbents, captures up to 90% of the CO2, reduces soot and NOx to Tier 4 levels, then liquefies the gas to be sold into a supply-constrained industrial CO2 market. Operators share the revenue, so cutting emissions becomes a line item that pays rather than one that costs.
Beewise
Beewise builds the BeeHome - a solar-powered, AI-driven robotic beehive that monitors and treats up to 24 honeybee colonies in real time. Founded in Israel in 2018 and now headquartered in San Ramon, California, the company is using computer vision, machine learning and precision robotics to cut annual colony losses from ~40% to under 10%, protecting the pollinators behind a third of the global food supply.
