FyberX

What FyberX does

FyberX (incorporated as FyberX Holding, LLC in Delaware and operating commercially through its Williamsburg, United States base) develops foundational infrastructure for processing raw agricultural and marine biomass into refined natural fibers. Its core offering is a proprietary fluid dynamics-based process that converts agricultural and marine waste — feedstock that would otherwise be burned or landfilled — into high-purity dissolving pulp, which is then extruded into regenerated cellulose fibers and cottonized bast fibers. The technology is positioned to consume 55% less power and 75% less water than traditional Kraft pulping methods, and to produce biodegradable fibers that directly substitute for petrochemical textile inputs.

The company monetizes through two complementary streams: direct B2B sales of sustainable fiber materials to fashion and textile brands (operating under its consumer-facing Erthe sub-brand), and technology licensing — exemplified by an exclusive March 2024 licensing agreement with GreenKey and an international strategic alliance with Toyoshima announced the same month. Customer segments are fashion and apparel brands and textile manufacturers seeking sustainable, traceable fiber alternatives with lower environmental impact, including reduced power and water consumption in fiber production.

The company is a private, deep-tech, pre-commercial-to-early-commercial entity with 11–50 employees, two disclosed SEC-exempt securities offerings totaling roughly $1.75M, no publicly disclosed revenue, and no disclosed patents, certifications, or named end customers. Its leadership team consists of CEO Benjamin Young and Founder/Chief Commercial Officer Klaas Eleveld. Strategic signaling to date centers on partnership-driven commercialization rather than direct market capture.

Core offering

FyberX develops and operates foundational infrastructure to process raw agricultural and marine biomass into refined natural fibers, primarily regenerated cellulose fibers and cottonized bast fibers. Operating through its Erthe brand, the company uses proprietary fluid dynamics-based biomaterial technology to convert agricultural and marine waste into high-purity dissolving pulp, then into biodegradable fiber alternatives to petrochemical textiles for fashion brands and textile manufacturers.

Product overview

FyberX is an advanced material innovation company operating primarily through its Erthe brand. The company offers a portfolio of sustainable textile products centered on two main fiber offerings: Regenerated Cellulose Fiber produced through proprietary fluid dynamics technology, and Cottonized Bast Fiber as a nature-grade alternative. The technology converts agricultural and marine biomass waste into high-performance fibers that biodegrade, providing direct alternatives to petrochemical-based textiles.

Direct peers

• Lenzing AG: Global leader in wood-based dissolving pulp and regenerated cellulose fibers (lyocell/Tencel, modal, viscose). Most direct comparable for FyberX's regenerated cellulose fiber product, with similar end markets in fashion and textile brands.
• Sateri: World's largest producer of dissolving pulp and viscose staple fiber under RGE Group. Direct competitor in cellulose-based textile fibers and shares FyberX's positioning as a sustainable MMCF supplier to apparel brands.
• Aditya Birla Group (Birla Cellulose): Operates Birla Cellulose, one of the largest manufacturers of viscose staple fiber and dissolving pulp globally. Comparable as a competing MMCF supplier targeting the same fashion/textile end markets.
• Eastman Chemical (Naia): Producer of Naia cellulosic staple fiber, a regenerated cellulose yarn targeting apparel brands seeking sustainable alternatives. Directly comparable to FyberX's regenerated cellulose fiber offering with similar customer-facing sustainability story.

Emerging players

• Spinnova: Finnish technology company producing sustainable textile fibers from wood and agricultural waste without dissolving or chemical processes. Comparable as an emerging biomaterial fiber competitor targeting fashion brands with sustainability positioning similar to FyberX.
• Renewcell: Swedish producer of Circulose, a recycled dissolving pulp made from textile waste. Comparable as an emerging circular-cellulose alternative targeting fashion brands — although focused on recycling rather than agricultural feedstock, it competes for the same MMCF customer wallet.
• Bolt Threads: US-based biomaterials company producing sustainable textile fibers (e.g., Mylo mycelium-based, b-silk protein). Comparable as an early-stage, brand-facing alternative-fiber company leveraging proprietary bio-based technology, similar to FyberX's biomaterials positioning.
• Natural Fiber Welding: US developer of plant-based, fully biodegradable materials (Mirum, Clarus) targeting fashion and footwear brands. Comparable as an emerging sustainable materials company with similar B2B-to-brand go-to-market and sustainability narrative.

Broad incumbents

• Sappi: Global dissolving pulp and specialty paper producer with significant dissolving wood pulp capacity. Comparable at the upstream pulp step FyberX performs (dissolving pulp production) but operates across a much broader pulp and paper portfolio.
• Domtar: Major North American pulp and paper producer with dissolving pulp and biobased materials ambitions. Comparable as an incumbent pulp producer FyberX may need to displace or partner with at the upstream feedstock/processing layer.
