Fiberly

What Fiberly does

Fiberly is a biomimicry-driven materials science startup that transforms discarded cellulosic textile waste into regenerated fibers engineered to replicate the molecular architecture of natural cotton. The company operates a proprietary six-stage process — AI-guided R&D, post-consumer/post-industrial waste collection, non-toxic solvent dissolution, biomimetic extrusion using spinnerets and electric fields, controlled phase regeneration, and closed-loop solvent and water recovery — to produce fibers the company states match or exceed virgin cotton in softness, breathability, absorbency, and hand feel, while using 100% waste-derived feedstock.

The technology platform integrates ML models trained on proprietary lab data for predictive fiber morphology modeling, computer vision that automatically scores fiber quality from microscopy images, and Bayesian optimization to select next R&D experiments, reducing trial-and-error cycles. Cellulose is recovered at its purest molecular state via non-toxic solvents and reconstituted through biomimetic extrusion to reproduce cotton's multi-layered structure, including twisted ribbon shapes, flattened cross-sections, and hollow cores. The closed-loop solvent and water recovery system is designed to minimize environmental footprint and enable production in water-stressed regions, contrasting with mechanical recycling which degrades fiber length and quality with each cycle.

Fiberly pursues a B2B direct sales model targeting fashion brands and apparel manufacturers seeking sustainable fiber alternatives to virgin cotton, with revenue generated through fiber sales (no pricing publicly disclosed). The company is headquartered in Toulouse, France with operations in Buenos Aires, Argentina, has a team of 1–10, and has raised a single disclosed funding round of $150,000 from the Biomimicry Institute in July 2024. Market positioning is supported by alignment with the EU Strategy for Sustainable and Circular Textiles, France's AGEC anti-waste law, and emerging global extended producer responsibility mandates, and by industry recognition including the GFA TRAILBLAZER 2026 (Top 9 of 180) and H&M Foundation Global Change Award 2026 (Top 20 of 450+).

Revenue model

1. Regenerated Cellulosic Fiber Sales: Selling high-quality fibers produced from discarded textile waste to fashion brands and manufacturers. The fibers match or exceed the softness, breathability, absorbency, and hand feel of virgin cotton, positioned as a sustainable alternative for the fashion industry.

Core offering

Fiberly fundamentally produces and sells regenerated cellulosic fibers made from discarded post-consumer and post-industrial textile waste. Using a proprietary biomimicry-driven chemical process, the company replicates the molecular architecture of natural cotton to deliver fibers with cotton-equivalent softness, breathability, absorbency, and hand feel, sold directly to fashion brands and apparel manufacturers as a sustainable alternative to virgin cotton.

Product overview

Fiberly offers a single unified technology platform — a biomimicry-driven fiber transformation process that converts discarded cellulosic textile waste into regenerated cotton-equivalent fibers. The platform integrates six sequential stages: AI-guided R&D, collection of post-consumer and post-industrial textile waste, non-toxic solvent dissolution, biomimetic extrusion, regeneration, and closed-loop recovery. This is not a modular product architecture but rather an end-to-end proprietary process technology.

Direct peers

• Worn Again Technologies: Worn Again Technologies develops chemical recycling processes to separate and recover polyester and cellulose from textile waste for fiber regeneration. Comparable to Fiberly in targeting cellulosic fiber recovery from textile waste for fashion industry applications.
• Spinnova: Spinnova produces sustainable textile fibers from wood pulp and waste using a mechanical process. Comparable to Fiberly as a next-generation sustainable fiber producer targeting fashion brands seeking alternatives to virgin cotton, though using a different (mechanical) technology approach.
• Renewcell: Renewcell was a Swedish chemical recycler producing Circulose, a dissolving pulp from textile waste used to make regenerated cellulosic fibers. Directly comparable in technology and target market to Fiberly, though the company filed for bankruptcy in 2024, illustrating both the opportunity and execution risk in the space.
• Ambercycle: Ambercycle uses chemical processes to regenerate fibers from textile waste, including cellulosic blends. Comparable to Fiberly as a textile-to-textile chemical recycler serving fashion brands with circular fiber solutions.
• Circ: Circ develops chemical recycling technologies to recover and regenerate cellulose and polyester from blended textile waste. Directly comparable to Fiberly as a chemical recycler targeting fashion brands seeking closed-loop fiber solutions.
• Infinited Fiber Company: Infinited Fiber Company produces Infinna, a regenerated cellulose fiber from textile waste using a chemical process. Directly comparable to Fiberly's molecular-level regeneration of cellulosic waste into cotton-equivalent fibers, targeting the same fashion brand customers.

Emerging players

• Re&Up: Re&Up is a Turkish-Italian company recycling cotton and textile waste into regenerated cotton fibers for fashion brands. Comparable to Fiberly in targeting the same cotton-equivalent recycled fiber market, though Re&Up is further along in commercial production.

Broad incumbents

• Birla Cellulose: Birla Cellulose is one of the world's largest producers of man-made cellulosic fibers (viscose, modal, lyocell) for the textile industry. Comparable to Fiberly as a major supplier of regenerated cellulose fibers, though operating at massive scale with virgin wood feedstock.
• Eastman (Naia): Eastman produces Naia Renew, a cellulose acetate fiber made from recycled materials including textile waste. Comparable to Fiberly as a large established chemical company developing recycled cellulosic fibers for fashion brands, though Eastman has a much broader product portfolio.
• Lenzing Group: Lenzing is a leading producer of regenerated cellulose fibers (Tencel/Lyocell) from sustainably sourced wood pulp. Comparable to Fiberly as a major producer of cotton-equivalent cellulosic fibers for the fashion industry, though using virgin wood feedstock rather than textile waste.
