Learn to let go (fast)

You can never fire that person fast enough. This is a lesson that countless entrepreneurs have remarked about their first company. Always, they felt that if they gave that one guy a little more time, he would catch on. It rarely happened, and never in time. Also, how to handle the '5th wheel' founder. The guy who was there in the early years, but now, time/requirements/developments/stage have passed him by. He was fantastic when the company was 5 people, but now that you're at 80, he's still running it like the company's at 5 people. the quick answer, get rid of him. The right answer: buy him out with a little bit of skin left in the company, let him enjoy the success, when it happens, but also give him a GOOD way to escape out of the business. If he's not being effective in an 80 person company, he's probably not happy, and want to recreate the feel of a 5 man company.

Help him out with that, get him funding, be his first 'customer', put him in touch with young entrepreneurs/companies who are at 4 people, or 8 people. Let him go do what he likes, in an environment he enjoys, instead of trying to accommodate him in a situation he's over his head.
