Vesting, equity, salaries, etc.
yeti: It really depends how critical the team are and how much they are giving up to join you.  In my case, I agreed with my co-founder (engineering leader) to just do it as up front equity rather than vesting and we agreed 20% plus a nominal salary (before dilution in funding rounds).  IMO Don't be too greedy and try to retain too much yourself, your founders will be key to your success or failure.And then for the others who joined after we did it as share options, up to 4%.  A way to calculate is to use sweat equity.. what would they/you normally get working for a large company for that time against the valuation of the company you work out.
