500 Startups, the U.S.-headquartered VC firm hit by scandal last year after co-founder Dave McClure resigned following allegations of sexual misconduct, has announced an unconventional deal that sees Abu Dhabi Financial Group (ADFG) take a stake in its parent company. It is normal for VC firms to work closely with big corporates as LPs that supply money for their funds — the Middle East has proven to be fertile hunting ground for the likes of 500, Uber and Softbank — but direct investment in parents is not common in VC-land.
