Software as a service for healthcare. We do vary salaries based on experience and function, but there is not much of a difference between senior devs and management. We're only a small business of 10 to 20 employees though. It works reasonably well (and we're 15 years old by now); the biggest threat is external market conditions and compliance requirements (because healthcare just is a demanding field).

I bet you get more done with 20 employees than most conglomerates do with 2000. Better incentives.

Robert Bosch GmbH would be a good example.

It's a worker's co-operative. There are all sorts in the US. In SF there are (or were) supermarkets that are organised like this.
