Some good thoughts here, Beril. I’ll reiterate something I said above. A cofounder should be someone who the business could not get off the ground and operate without, not necessarily someone who is there at the beginning. They need to be enthusiastic yes, but they also need to have experience and skills that the other cofounder(s) do not.
And while it shouldn’t be one person “calling the shots” — you do need one person who makes decisive calls when the room is split. I’ve seen startups stagnate and die because the cofounders couldn’t agree on direction. The machine needs to operate whether democracy is working or not. But yes, in all other aspects, it needs to be a team approach.
Thanks for your input!
