Well, we (http://www.shadowcat.co.uk/ http://www.shadowcat.co.uk/) were founded by me, who plays the "lead hacker" role, and a friend of mine who handles graphic design, marketing, client contact, accounts, contracts etc. Basically he provides the business half of the "developer abstraction layer" that Joel Spoelsky describes (we also have an extremely talented sysadmin who handles that half) so I and my team can get on with building software. Seems to work pretty well for us, but we're bootstrapped so we've been building a stable consultancy business first to fund product development and therefore maybe aren't an example of the style you're looking for.
