Unfortunately, there isn't an exact science to dilution/valuation in most cases, especially in the very early stages. Ultimately you need to sell as much/as little of the company as is required in order to secure the resources you need to be successful. Owning 100% of something that isn't particularly is always going to be worse than owning 1% of a billion dollar company.

That said, there are generally some norms around percentages for co-founders, and employee option grants can be benchmarked against comp data that you can find in Carta or Pave. And managing your cap table on Carta will help to make things easier in the future for investors/employees/the company to manage the cap table as it grows and changes.

Happy to chat more if that would be helpful!
