At a very early stage but well-funded startup, where everyone is relatively equal in age, capability or experience, I think the idea of everyone making the same 'monthly nut' money, like $100K per annum could be appealing. In the Bay Area, I actually think $100K after taxes/medical/401K deductions would be reasonable, high side. Cash/Stock bonuses could then be variable based on contribution. Equality, transparency and trust would be key
