Therapeutic plasma exchange (TPE) service provider for clinics, offering outpatient blood-cleaning for longevity
Founded in January 2024 by Eric Verdin, Brad Younggren, and Robbie Schwietzer, Circulate Health provides therapeutic plasma exchange procedures for longevity and anti-aging applications. Based in Novato, California, the company partners with existing functional medicine clinics by supplying the necessary medical equipment, trained nurses, and clinical protocols to administer these outpatient blood-cleaning treatments. These direct-to-consumer sessions currently cost individual patients approximately $8,000 to $10,000 per treatment and are not covered by traditional health insurance plans at this time. Since May 2024, the enterprise has successfully facilitated over 1,000 treatments across a rapidly growing network of 24 partner clinics located in eight different states. To fuel further expansion to fifty locations by the end of 2025, the organization recently secured $12 million in seed funding led by Khosla Ventures, alongside Seaside Ventures and CSC Ventures.

Circ is an advanced recycling technology company that develops patented processes to deconstruct mixed-textile garments, primarily polyester-cotton blends, back into reusable raw materials.[1] It serves the fashion and apparel industry by tackling textile waste, reducing reliance on virgin resources, and enabling a circular economy for clothing production.[1] Since receiving investment from Circulate Capital in 2021, Circ has achieved significant growth, securing over $30 million in Series B funding from major players like Inditex and Breakthrough Energy Ventures.[1]
This positions Circ as a key innovator in sustainable materials recovery, addressing the massive environmental challenge of textile waste—where most fabrics are unrecyclable blends—while gaining traction with global apparel giants.[1]
Circ emerged from the need to solve the fashion industry's recycling bottleneck, with founders leveraging expertise in chemical engineering and materials science to pioneer textile-to-fiber recovery.[1] The company's patented technology specifically targets the dominant polyester-cotton mixes that dominate manufacturing, turning a waste problem into a resource loop.[1] A pivotal moment came in 2021 with Circulate Capital's investment, which catalyzed broader validation and propelled a $30+ million Series B round backed by industry leaders like Inditex and Bill Gates' Breakthrough Energy Ventures, marking rapid scaling from pilot to commercial viability.[1]
(Note: Search results provide limited founder details; the backstory centers on technological innovation and key funding milestones.[1])
Other entities like a digital experiences firm or an Indian IT OPC lack Circ's prominence in tech innovation.[2][3][4]
Circ rides the circular economy wave in fashion, where textile waste exceeds 92 million tons annually, driven by regulations like the EU's waste directives and consumer demand for sustainability.[1] Timing is ideal amid escalating scrutiny on fast fashion's environmental toll—polyester production alone rivals aviation emissions—positioning Circ's tech as a market-forcing solution.[1] Favorable forces include corporate net-zero pledges from brands like Inditex and rising venture interest in climate tech, amplifying Circ's ecosystem influence by enabling scalable recycling infrastructure.[1]
Circ is poised for expansion into full commercial plants, leveraging its funding to process millions of garments yearly and partner with more brands.[1] Trends like advanced materials recovery and policy-driven circular mandates will accelerate adoption, potentially evolving Circ into a standard for textile recycling.[1] As investor backing grows, expect Circ to reshape fashion's supply chains, tying back to its core mission of turning waste into wardrobe essentials.[1]
