Guayakí (now Yerba Madre): The more you drink, the more the Atlantic Forest regenerates. The Atlantic Forest (Mata Atlântica), spanning Brazil, Paraguay, and Argentina, is one of Earth's most biodiverse and most threatened ecosystems — over 9,000 of its 20,000 plant species exist nowhere else. In 1996, Argentine food scientist Alex Pryor and David Karr launched Guayakí (recently renamed Yerba Madre) as a Cal Poly graduation project, betting on a then-radical idea: “Market Driven Regeneration” — the more yerba mate sells, the more standing forest is protected, and the more Indigenous people and smallholders can keep living in and tending the forest. Guayakí sources shade-grown (not monoculture) yerba mate from communities including the Aché, supports schools, water, health, and nurseries with a Fair for Life premium (10% of purchase value), and creates living-wage jobs well above the local average. A founding-member B Corp in 2007, it became the world's first “Regenerative Organic Certified Gold” yerba mate in 2025. Its original 2020 goals (protecting 200,000 acres and 1,000 families' forest livelihoods) were — per the company — met and exceeded; now over 2,000 families grow mate in the shade, and even the jaguar has returned. The letter is A; certainty is medium. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q2; estimate based on public information.)

One person’s story (N1)
+ before → after
The Aché Kue Tuvy people were forcibly driven from their ancestral subtropical forest in northeastern Paraguay in the 1970s and pushed to the brink of extinction by enslavement and massacre — but returned home in 2000. Today, an Aché team tends the forest for Guayakí, harvests shade-grown yerba mate, and earns a “living wage” well above the local average farmer. Stewardship of the forest has returned to the hands of people who have lived there for thousands of years. Margarita Mbygwangi, an Aché leader and longtime partner, says: “To me, this forest has life. I feel very strong energy. Growing the tradition of wild fruits and foods keeps us, and our grandchildren, healthy.”

- Guayakí (now Yerba Madre) is a founding-member B Corp (2007), became the world's first “Regenerative Organic Certified Gold” yerba mate in 2025, and was the world's first yerba mate handler to obtain Fair for Life Fairtrade certification. Featured in Doughnut Economics and Bioneers case studies, Harvard International Review (2020) defended it against the criticism of “exotic marketing by a white-owned company,” noting Guayakí consults local Indigenous people, funds the projects they actually need, and pays well above market price.P1 independent multi-benefit certification / B Lab / Regenerative Organic Alliance / Fair for Life

A second look
It is a structure where a U.S.-headquartered (California) company handles an Indigenous traditional product, drawing criticism of “neoliberal/exotic marketing” (rebutted by Harvard International Review 2020). Forest-“regeneration” area (200,000 acres, etc.) and impact figures are mainly company-reported (certification is independent). There are also consumer/labeling points (category iii, reference), such as a U.S. class action over yerba mate labeling (settled). It was renamed “Yerba Madre” in 2024-25.

How to read this assessment
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
Terms: Narrative Value = an assessment (A–G) of the distance between the story an organization tells and its reality / Ceiling meter = a visualization of the reachable upper bound / Watching = unconfirmed matters not counted / Protected stakeholders = people, animals, nature, and future generations. | Generated by: AI | As of: 2026-Q2 | Back to top
