Since you run a fairly flat organisation, do you ever promote the exceptional people that have worked with you for many years into the 'partnership' area of your company? I read somewhere that David was originally a contractor and then became a partner, but has this occurred for any other significant contributors to the company. I'm thinking 10+ years, has a solid and respected reputation within the company, etc.
