What RavenWindow does
RavenWindow is a Denver, Colorado-based for-profit company founded in 2006 that develops smart glass windows built on proprietary thermochromic technology. The company's core product dynamically modulates solar heat gain in response to temperature changes, positioning it within the energy-efficient building envelope and sustainable construction market. The technology is a passive, materials-science solution rather than an electronic or software-driven system, targeting architects, developers, and building owners seeking to reduce cooling loads and improve thermal performance.
The company operates at small scale, with 11-50 employees, and has raised approximately $7.6 million in disclosed funding across two rounds: a $5 million round in September 2012 led by Aravaipa Venture Fund with participation from King Hill Capital, and a $2.6 million round in October 2017 from undisclosed investors. Leadership comprises co-founders Alex Burney and Richard Powers, Co-CEO and Chairman Robert Fenwick-Smith, CEO and EVP of Sales and Marketing Del Bankston, and VP of Finance Shelly Marlin, suggesting a configuration weighted toward commercialization.
Revenue mechanics, pricing model, customer concentration, geographic footprint, and partner ecosystem are not disclosed in the available source data, and the company website returns only a loader/verification page. As a result, the company's current commercial scale, go-to-market motion, and revenue trajectory cannot be precisely characterized from the input.

RavenWindow product offering
Product offeringCore offering
RavenWindow manufactures smart glass windows that incorporate a proprietary thermochromic interlayer. The interlayer darkens automatically as the glass heats up from sunlight and clears again as it cools, passively controlling solar heat gain without electricity, wiring, or controls. The windows are designed for architects, building developers, and facility owners seeking energy-efficient, code-compliant dynamic glazing.

RavenWindow competitors and assessment
Company assessmentDirect peers
- View (View Dynamic Glass): View is the most direct competitor to RavenWindow in the smart/dynamic window category, offering electrochromic glass that electronically tints. Both target architectural windows for daylighting and energy management in commercial buildings.
- SageGlass (Saint-Gobain): SageGlass, owned by Saint-Gobain, manufactures electrochromic smart glass for windows and skylights. It competes directly with RavenWindow in the architectural dynamic glazing market.
- Halio (by Kinestral Technologies): Halio produces electrochromic smart glass windows for residential and commercial buildings. It targets the same smart window use case as RavenWindow with a tinting technology aimed at daylighting and energy savings.
Emerging players
- Research Frontiers: Research Frontiers licenses SPD (suspended particle device) smart glass technology used in architectural windows and skylights. It is comparable to RavenWindow as an enabling smart glass IP holder in the dynamic window category.
- Cricursa (Thermochromic Glass Producer): Cricursa produces curved and specialty architectural glass including thermochromic glass products. It is a niche peer using the same thermochromic tinting technology approach as RavenWindow in architectural applications.
Broad incumbents
- Guardian Glass: Guardian Glass is one of the world's largest manufacturers of float and coated architectural glass, including low-E and solar control products. It is broadly comparable as an incumbent player in energy-efficient window glass that RavenWindow's thermochromic product competes with.
- Saint-Gobain: Saint-Gobain is a global building materials conglomerate that produces flat glass and owns SageGlass. It represents the broad incumbent competitive context in which RavenWindow operates and a likely acquirer profile.
- NSG Group (Pilkington): NSG/Pilkington is a major global manufacturer of flat and architectural glass, including energy-efficient coated products. It is comparable to RavenWindow as a large incumbent in the building glass market.
- Vitro Architectural Glass: Vitro is a large North American architectural glass manufacturer offering low-E, solar control, and coated glass products. It competes with RavenWindow in the energy-efficient window glass category at the incumbent scale.
- Cardinal Glass Industries: Cardinal is a major U.S. manufacturer of residential and commercial architectural glass, including high-performance IGUs and coated glass. It is comparable as a domestic incumbent in the energy-efficient window glass market.
