He also juggles running an Irish clothing company; investing in Elevation Partners, a $1.9 billion private-equity fund that has taken big stakes in Forbes Media and Palm; and drumming up support for Product Red, a for-profit marketing concern signing up corporate partners to raise money for the Bono-supported Global Fund.
