Should I use a dynamic equity split like Slicing Pie instead of fixed percentages?

The short answer

Dynamic models like Slicing Pie allocate equity based on actual contributions over time, which is genuinely fairer at the pre-funding grunt stage when nobody knows who'll do what. The trade-off: they're harder to explain to investors and to administer, so many teams use them as a mental model then convert to fixed equity plus vesting at incorporation. Use it to inform your thinking; don't let it become a bookkeeping nightmare.
