What NSS Water does

NSS Water Enhancement Technology AB, operating as NSS Water, is a Sweden-based (Bengtsfors) deep-technology startup developing membrane distillation-based water purification systems branded as WET (Water Enhancement Tool). The platform produces Nanopure Water (NPW®) on demand, free of nano contamination above 5–10 nanometers, and is targeted primarily at semiconductor wafer-cleaning, etching, CMP, and chemical-dilution processes, with secondary applications in R&D laboratories and life sciences. The company holds 5+ patents granted or pending arising from more than 8 years of research, and markets WET Nano One (the first commercial product, for R&D and laboratories) while positioning WET SEMI as an upcoming solution engineered for semiconductor manufacturing operations that can be retro-fitted into existing customer equipment.

The commercial model is direct, enterprise sales-led: a quote-based engagement initiated via a 'Book a Meeting' call to action on the company website, followed by solution design, customization, and on-site installation or retro-fit. Revenue mechanics are anchored on hardware sales of WET systems (with implied multi-year service/maintenance contracts), supplemented by custom engineering; pricing is not publicly disclosed. Customer segmentation is vertical-led, prioritizing semiconductor manufacturers, followed by R&D/laboratory users and life sciences. Distribution is single-channel direct enterprise sales; no third-party resellers are disclosed.

Capitalization is early-stage and venture-backed, totaling 7.2 million SEK raised in a February 2026 share issue led by Grow Venture Partners and SkyDeck Europe alongside Longrun Capital, GU Ventures, and Vasa Angels. Recognition includes winning the ICT Grand Challenge (Batch 2) in May 2025 and inclusion in Ny Teknik's top 33 Swedish deep-tech startups in late 2025. The leadership team comprises founder/CEO Björn Holmström, CTO Erik Östreng (appointed February 2026), Chairman Deborah Lygonis, with Bengt Wallin heading production/sales and Mikael Funa leading business development. The company currently employs 1–10 people.

Core offering

NSS Water designs, manufactures, and sells water purification systems based on its proprietary membrane distillation WET (Water Enhancement Tool) technology. These systems produce Nanopure Water (NPW®) on demand, free of nano contamination above 5-10 nanometers, primarily for semiconductor manufacturing and laboratory/R&D applications. The WET Nano One is the first commercial product targeting laboratories, universities, and R&D departments.

Product overview

NSS Water offers a product line centered around WET (Water Enhancement Tool) technology that produces Nanopure Water (NPW®). The portfolio consists of three offerings: WET Nano One (the first commercial product for R&D, universities, and laboratories), Customized Solutions (scalable and retro-fittable systems for various applications), and WET SEMI (an upcoming product specifically for semiconductor manufacturing). All products use patented membrane distillation technology to produce water free of nano contamination above 5-10 nanometers, reducing water consumption by up to 90% in certain production steps.

Broad incumbents

• Hitachi High-Tech (formerly Hitachi Industrial): Sells semiconductor manufacturing equipment and related process systems, including water and chemical delivery solutions for fabs. Comparable as it serves the same semiconductor manufacturing customers and competes for fab upgrade budgets alongside NSS's WET SEMI.
• Veolia Water Technologies (incl. former Sidem/Evoqua UPW): Global leader in ultrapure water systems for semiconductor and microelectronics fabs. Directly comparable because it sells the incumbent UPW loops that NSS Water's WET product aims to retrofit or disrupt, and shares the same fab customer base and qualification pathways.
• Organo Corporation: Japanese specialist in industrial pure and ultrapure water systems for semiconductor, LCD, and pharmaceutical customers. Closely comparable because of its focus on high-purity process water for semiconductor manufacturing, the same end market NSS targets with WET SEMI.
• Entegris: US-based supplier of specialty materials and fluid handling systems to semiconductor manufacturers, including high-purity water and chemical delivery. Comparable target market (semiconductor fabs) and overlapping role in process contamination control where NSS Water also plays.
• SUEZ Water Technologies & Solutions (now Veolia): Long-established ultrapure water solutions provider for semiconductor fabs globally. Comparable incumbent serving the same semiconductor customers with the same UPW process that WET aims to disrupt.
• Applied Materials (semiconductor water/chemical systems via AKT and others): Global semiconductor equipment leader offering adjacent process and chemical delivery solutions to fabs. Comparable in serving the same semiconductor customer base and in providing process-enabling equipment, even though its core focus is deposition/etch rather than pure water specifically.
• Kurita Water Industries: Major Japanese industrial water treatment company with a dedicated ultrapure water business serving semiconductor fabs in Asia. Comparable target customer (semiconductor manufacturers), overlapping water purification technology stack, and similar value proposition around high-purity process water.

Regional players

• Atlas Copco (Industrial Compressor / Power & Flow): Swedish-headquartered industrial equipment company with strong semiconductor exposure and water/process gas handling solutions. Comparable Swedish regional industrial DNA and overlaps in serving the same semiconductor customer base with critical process utilities.

Emerging players

• Gradiant Corporation: US-based water technology company focused on industrial water treatment and reuse, including semiconductor and microelectronics applications. Comparable emerging player working on advanced membrane and selective separation technologies that NSS also uses for ultrapure water.
• REAL Water Tech / Liquinex: Smaller industrial water purification specialist serving microelectronics and life sciences with high-purity water systems. Comparable as a more nimble player competing with incumbents in the same semiconductor/UPW niche where NSS operates.
