I recently started a company with a friend it has gone from a sole trader biz to now a LLC with me coming onboard. My friend has 15 years exp and I have 2. He built the business and I am coming in. the LLC is 50/50 ownership. Should I pay a premium to him in perpetuity through a wage disparity? or should there be a point in our future where if I am bringing in the same value I can fairly expect wage parity?
