Hmmm. I don't work for what would necessarily be called a primal-friendly company. However, they have a *great* philanthropic model -- 1-1-1.
1% profit--money donated to non-profit causes
1% product--support over 6000 non-profits for free on the software
1% productivity--they pay me 4 hours per month to go work with non-profits. It's a huge part of the company culture -- you're expected to go do non-profit work on a regular basis.
They purchase carbon offsets for the office buildings, trying to reduce their carbon footprint. All the flatware in the office is "spudware" -- made from potatoes and 100% compostable. They frequently "fine" departments that leave fancy screen-savers running, instead of turning off the screen (and saving electricity.) They moved from bottled water to filtered water systems. And so on.
Maybe instead of just primal as your focus, you could also look at how companies use their influence in the community? Just my $.02.
If I don't live my dream, who will?
