Hi Brian,
We've implemented Holacracy within 5 stores, 3 restaurants and a snack. Check out Scarabée biocoop (organic food industry): http://lexcellenceenholacracy....ee-biocoop-holacracy
We are translating a 40 minutes interview of Isabelle Baur (Holacracy Engagement Lead and CEO) where she explains her experience after 10 months of practice. I will send you the link as soon as it is available in english unless you speak french of course.
Kind regards,
Margaux
