That's some good advice. But, don't forget with enterprise customers you can offer to sell the company to them. 2-20 million for a long term strategic advantage plus your proven track record can be seen as net win for everyone. And if negotiations break down they are less likely to think they already own you. I would be cautious of any sort of long term profit sharing, but offering to share a few years revenue from any 'connections' made in the industry can offset the feeling you are burning them by sharing the secret sauce.
