I guess ideally each person would contribute something valuable to the team (maybe something the others dont have), making the even 1/3 split justified. The person you talk about would be contributing their domain knowledge. If one persons contribution is low to point that an even split couldn't be justified, then I would just make sure that you really need them as a co-founder, as apposed to an early employee. If things are close though I would try to justify the even split so everyone is on the same plane. In my opinion its just not worth getting greedy over small percentages, if it could compromise the success of the team or cause internal strife. The following quote comes to mind: "I'd rather have a slice of the watermelon than a whole grape."
