Nelumbo is a materials technology company specializing in advanced surface modifications to enhance energy efficiency and durability in products like refrigeration systems, HVAC units, and textiles. Founded in 2015 by UC Berkeley engineers, it developed a scalable platform for anti-icing, corrosion resistance, and water-repellent coatings, reducing carbon emissions and energy use in heat exchangers and beyond[1][2][4]. The company shipped products to customers, deployed pilot manufacturing, and raised $21.35M before its acquisition by Kuraray in April 2025, accelerating global expansion into polymers and fibers[2][5].
Serving industries such as HVAC, refrigeration, and textiles, Nelumbo solves persistent challenges like frost buildup and corrosion, which degrade efficiency in air conditioners and industrial systems impacting billions. Post-acquisition, as "Nelumbo, A Kuraray Company," it continues innovating with 24 patents in areas like fluid dynamics and ceramics, recognized by the U.S. Department of Energy and investors including Danfoss Ventures and Photon Fund[1][2][4].
Nelumbo emerged from UC Berkeley in 2015 (some sources note 2016), founded by engineers Dave Walther, Ph.D., Liam Berryman (current CEO), and Lance Brockway, Ph.D., driven by a vision to mainstream materials science for societal impact[1][4][5]. The idea stemmed from their lifelong passion for surface technologies, targeting frost and corrosion in heat exchangers—a market with massive energy waste and global reach[1][4].
Early traction included partnerships, product shipments, and pilot scaling, earning accolades like Forbes 30 under 30, Cyclotron Road, and U.S. Department of Energy recognition. Funding milestones featured a $14M Series A expansion led by Prime Mover’s Lab and UTEC, culminating in Kuraray's 2025 acquisition after an exclusive 2023 partnership on fiber applications[2][5][6].
Nelumbo rides the wave of sustainable materials innovation, addressing climate-driven demands for energy-efficient HVAC and refrigeration amid rising global cooling needs—projected to consume 10% of electricity by 2050. Its timing aligns with PFAS phase-outs and net-zero goals, replacing harmful chemicals with scalable, drop-in coatings that cut emissions in billion-unit markets[1][2].
Market forces like regulatory pressures on energy use and corporate sustainability pledges favor its tech, influencing ecosystems via alliances with giants like Kuraray (fibers/textiles leader) and Danfoss (HVAC). As a Kuraray asset, it amplifies U.S.-Japan tech transfer, boosting adoption in high-value chains where Japanese firms dominate[4][5].
Post-2025 acquisition, Nelumbo will likely expand Kuraray's portfolio into energy-efficient surfaces for global HVAC, textiles, and beyond, leveraging Kuraray's manufacturing scale for mass adoption. Trends like electrification, decarbonization, and bio-based alternatives will propel growth, potentially disrupting $100B+ refrigeration markets.
Its influence may evolve from startup pioneer to integrated platform, enabling "fingerprints" on everyday products while sharing value across supply chains—echoing its founding mission to redefine materials for a sustainable world[1][5].
Nelumbo has raised $20.0M across 2 funding rounds. Most recently, it raised $14.0M Series A in April 2020.
