Richard Branson has tapped a boutique investment bank to raise funds for two space companies within the Virgin Group. Branson backed out of talks with Saudi Arabia's sovereign wealth fund for more than $1 billion in investments after the disappearance of the journalist Jamal Khashoggi, which has been attributed to the country's government. LionTree Advisors, founded by former UBS executives, previously advised Liberty Global's $23.3 billion takeover of Virgin Media. Sir Richard Branson is looking for another source of funding for two of his space companies after cutting ties with Saudi Arabia.
