Unfortunately not any that still exist. The only companies that seem to be able to accomplish it are early stage startups; because it is orders of magnitude easier to do with such a small group of people. Code School & Envy Labs are my personal examples.

I do think it is possible at large companies. I've built, been part of, and talked with managers that have created teams that obviously have low load (due to how much they produce, satisfaction with work, and level of trust). But it never lasts for long. Inevitably something like Radford is implemented by HR or some VP gets the reorg itch and tears down the system because these sorts of details haven't made it into boardrooms beyond "two pizza teams". Pluralsight and Amazon are my personal experiences with large companies.
