Assuming this means 25/75 percent, there is a strong counterpoint to this: 99% of the work is ahead of you. 95% of the risk is ahead of you. So why get only 2

Assuming this means 25/75 percent, there is a strong counterpoint to this: 99% of the work is ahead of you. 95% of the risk is ahead of you. So why get only 25% if the CEO gets 75? Here’s a split I would want if joining an early startup as CTO / co-founder-in-all-but-name: 40% CEO. 30% CTO. 30% Employee pool (this assumes another big chunk will need to be given to at least one other key hire in the next year).
