Seattle-based textile recycling startup Ravel announced on September 17 the close of an oversubscribed $8.2 million seed round, with proceeds earmarked to commercialize its technology for reducing blended textile waste back into new fibers. The round was led by One Small Planet, with significant participation from AP Ventures, and follow-on from Overlay Capital and Lichen Ventures; pre-seed lead At One Ventures and existing backers including Collateral Good and Betterway Ventures also increased their investments.

Key Points

  • Ravel closed an $8.2 million seed round led by One Small Planet, with participation from AP Ventures, At One Ventures and others
  • Its Purification Recycling process targets hard-to-separate blends such as polyester and spandex, purifying them into single-material fibers
  • Funds will take the company from its Seattle pilot plant toward scale-up, validating performance at production volumes and recruiting industry partners

Blends Are the Toughest Wall in the Recycling Chain

Ravel is targeting garments made from multiple materials. Blends give clothing durability, functionality and affordability, and account for the largest share of what people wear day to day, yet they are extremely difficult to break back down into recyclable single-material streams — widely recognized as the biggest obstacle in textile recycling. According to Textile Exchange's annual market reports in recent years, roughly 85% of textiles are concentrated in four major material categories, and these fibers are often blended together in finished products.

Ravel says its Purification Recycling process can handle mixtures long considered inseparable — including the polyester-spandex combinations common in performance apparel — and purify waste into single-material fibers through non-destructive, low-energy steps, with outputs usable in existing manufacturing processes. These technical characteristics are as stated by the company.

Ravel CEO Zahlen Titcomb said blended fiber materials offer countless advantages for clothing — it is blending that makes garments durable, practical and affordable — but existing infrastructure cannot recycle blends, which is precisely the problem Ravel set out to solve, tackling what other technologies have not.

Scaling textile-to-textile recycling is not just about collecting large volumes of old clothes. The harder problem is how to handle blended material and produce recycled feedstock manufacturers can actually use — at the right quality and price. By accepting mixed feedstock as-is, Ravel aims to eliminate the costly, logistically complex step of first sorting and then shipping pure waste streams, a bottleneck that has long plagued conventional recyclers.

Why Investors Are Betting

Jack Wielebinski of lead investor One Small Planet explained the appeal this way: Ravel offers a rare opportunity in recycling — a clear path to producing recycled materials cheaper than virgin ones; the company's technology converts complex material blends into virgin-quality feedstock, building a transparent, low-carbon, cost-effective supply chain and opening the door for more global industries to adopt circular models.

Helen Lin, a partner at pre-seed lead At One Ventures, sees feedstock as the variable that determines whether a recycling business succeeds or fails. She posed a series of questions: How much of a waste stream is actually usable? What purity does processing require? How far does it need to be transported? These factors determine unit economics, operational complexity and ultimately scalability. She said the team was impressed that Ravel recognized this early and designed its technology specifically around scale-up and feedstock challenges.

Ravel says that by putting industrial and economic viability first, its process requires no "green premium" imposed on the system and does not rely on subsidies to cover costs, with recycled output priced on par with existing textile materials. Investors view this price discipline as a lever for widespread adoption.

The Test Comes at Production Scale

The company, however, is still in the commercialization validation stage. Ravel plans to expand from its Seattle pilot plant, validating the technology across the entire supply chain and demonstrating performance at production scale. As extended producer responsibility (EPR) legislation increasingly puts textile waste on brands' and manufacturers' books, the company is seeking industry partners to validate blended waste as feedstock and embed its materials into existing manufacturing supply chains. Whether its cost and environmental goals hold up at scale remains to be proven.

For the used-clothing recycling industry, the significance of this round is this: whether a technology pathway holds is shifting from lab metrics to a dual test of production cost and feedstock compatibility; whoever can digest the hardest-to-process blended waste and bring recycled fiber to price parity with virgin materials is better positioned to capture the compliance-driven procurement demand that brands and manufacturers are adding under EPR pressure.
