What eLstar Dynamics does

eLstar Dynamics B.V. is a Dutch clean-tech scale-up founded in 2019 and headquartered in Eindhoven's Brainport high-tech region, with a chemical engineering operation in South China. The company develops and industrializes eclipse™, a proprietary adaptive smart glass product built on its patented Electrophoretic Light Modulator (ELM) technology. Unlike conventional electrochromic glass that switches slowly and exhibits blue or yellow tints, eclipse™ uses an electric field to aggregate and redistribute pigment particles across the glass surface, achieving instant switching, a neutral 98 CRI clear state, light transmission from 0.2% to 70%, ultra-low power consumption (~1W/m²), and panel scalability up to 2.94m x 3.37m with curved-substrate compatibility. The product blocks up to 85% of solar heat gain and can reduce building HVAC energy consumption by up to 30%.

eLstar sells across four customer segments — glass processors (integration into architectural facades, skylights, and automotive glazing via existing lamination lines), architects specifying dynamic glazing for LEED/BREEAM/WELL-certified projects, residential homeowners (via certified installers), and electric-vehicle OEMs integrating ELM modules into sunroofs and side windows. The revenue model is primarily hardware sales of eclipse™ panels to glass processors and OEMs, with licensing of its international patent portfolio (covering chemistry, electrode designs, and integration methods) and integration/professional services as secondary streams. Pricing is project-based and not publicly disclosed.

The go-to-market motion is multi-channel: enterprise field sales to glass processors and OEMs globally, OEM-embedded integration for EV programs, architect specification engagement during building design, and a certified-installer channel for residential windows. Manufacturing follows an asset-light model — eclipse™ is 90% compatible with existing LCD and glass lamination production lines, enabling scaling through global partners rather than dedicated gigafactories. The company has raised approximately €23 million in total, including a €10 million Series A closed in December 2024 from an unidentified top-100 Dutch company, and is led by CEO Anthony Slack and Chief Strategy Officer Andrew Loxley.

Core offering

eLstar Dynamics develops and manufactures eclipse™, a proprietary smart glass based on Electrophoretic Light Modulation (ELM) that switches instantly between transparent and tinted states. The pigment-based technology uses electric fields to redistribute pigment particles across glass surfaces, blocking up to 85% of solar heat while maintaining a neutral 98 CRI clear state. Products are sold as finished glass panels for skylights, residential windows, and automotive (EV sunroof/window) applications, with the manufacturing process designed to be 90% compatible with existing LCD production lines.

Product overview

eLstar Dynamics offers a portfolio of adaptive smart glass products under the eclipse™ brand, powered by its proprietary Electrophoretic Light Modulator (ELM) technology. The product line includes Skylights and Residential Windows for architectural applications, as well as Automotive Glass for EV sunroofs and windows. All products share the same core ELM technology platform that enables instant switching between transparency states, blocks up to 85% of solar heat, and reduces building energy consumption by up to 30%.

Broad incumbents

• NSG Group (Pilkington): NSG/Pilkington is one of the world's largest glass manufacturers with products in automotive and architectural markets, including ongoing investment in electrochromic and switchable glazing. It is comparable as a broad incumbent in the addressable glass categories eLstar targets.
• AGC Inc. AGC is a global major glass manufacturer producing architectural, automotive, and specialty glass including switchable variants. As a partner and competitor, AGC represents both a potential licensee/customer for eLstar and a large incumbent with smart glass product lines targeting overlapping architectural and automotive customers.
• Gentex Corporation: Gentex is a large established supplier of electrochromic dimming technology, primarily for automotive rearview mirrors but with expanding automotive glazing and aircraft window programs. It overlaps with eLstar's automotive ambitions in electrochromic and dimmable glass for vehicle integration.
• Merck KGaA (Performance Materials / Smart Glass): Merck is a leading supplier of liquid crystal materials and licensable smart glass chemistry (e.g., Licrivision) used in switchable glass production. It is comparable to eLstar as a technology/materials provider enabling the broader smart glass ecosystem, including OEM partners.
• Continental AG (Automotive glass / surface): Continental is a major automotive supplier developing dimmable automotive glazing and integrated sunroof solutions for OEMs. It is comparable to eLstar's automotive OEM-embedded strategy, particularly for EV sunroofs and switchable side windows.

Emerging players

• Research Frontiers: Research Frontiers licenses SPD (Suspended Particle Device) smart glass technology for automotive sunroofs, aircraft windows, and architectural applications. It competes with eLstar's electrophoretic approach through alternative particle-based light modulation technology serving similar end markets.

Direct peers

• Gauzy: Gauzy is a global manufacturer of switchable smart glass using PDLC and other technologies, serving both architectural and automotive markets. It directly competes with eLstar across multiple verticals (architectural windows, automotive sunroofs) and pursues similar OEM-embedded distribution strategies.
• SageGlass (Saint-Gobain): SageGlass, a subsidiary of Saint-Gobain, is the leading electrochromic smart glass provider for architectural facades and skylights. It is the most direct competitor to eLstar's eclipse™ in the building-integrated dynamic glazing category, addressing the same architects and building owners with similar functional value propositions.
• View (formerly View, Inc.): View was a high-profile electrochromic smart glass competitor that commercialized dynamic glass for commercial buildings at scale before ceasing operations. It remains a relevant direct competitor and benchmark for go-to-market lessons in the architectural smart glass category.
• Halio (Cardinal Glass Industries): Halio produces electrochromic smart glass for residential and commercial buildings, now backed by Cardinal Glass Industries. It competes head-to-head with eLstar in dynamic architectural glazing with neutral-tint switching, targeting similar architect and homeowner segments.
