As someone who is partnered in various ways with well over 20 people currently, I can honestly say that there is no "standard."
In the long run, you give as much (and only as much) as you have to, to get what you need to move forward.
I gave half of one business away to get the legal assistance I needed to move forward, otherwise it would have stalled. It's WELL worth it, because half of something is better than 0% of nothing. *smiles*
That same business has a third partner on spec. If she comes in, she will get 20%, 10% from each current partner's share. If she does not come in, we will part ways, owing a salary equal to $35,000/year for the time she worked, once money has been made.
Other partnerships are simpler, some more complex. For example, with my licensees, they only owe me once they start making money. Once they do, I get a percentage that starts high and goes down based on gross income per month.
However you choose to do it, get a good legal agreement in place. Otherwise, it can become a nightmare.
