Terra Viva is an agribusiness centered in São Paulo, Brazil begin by the Schoenmaker family in 1959 to grow gladiolas. Though not mentioned on their website, Gerard Endenburg consulted with the owner in the 1970s to develop the company using sociocracy. They now have more than a thousand workers and focus on bulbs and plants for flowers and vegetables.
Their website includes a discussion of the company’s philosophy including an organizational chart, but does not mention sociocracy or Endenburg.
A good research topic.
