A friend of mine (Xander) came to me with a business idea that seemed a good one and offered me to work on it. However, he was unable to negotiate with investors and we did not start.
One month later, another friend (Yann) called me and showed interest in investing money in an idea. I want to offer Xander's idea to Yann and start it. I don't want to break up with X, so I want to offer him to join us.
The problem is, if me and Xander started this together, Xander would've had a lot more share than now, because his amount of contribution will decrease drastically.
As there is a high chance of rejection by Xander, how can I properly elaborate the situation and ask him to join us so that things go well?
Xander is resourceful, so having him on the team is beneficial.
The idea is not a new idea, it's just a plan to produce an already built Tech device.
