Sergey Brin Nonprofit Gets $261 Million Lift in MapLight IPO

Sergey Brin’s name doesn’t appear in MapLight Therapeutics’ filings to go public, but the Google co-founder’s philanthropic ambitions got a big boost from the biotech’s market debut.

His nonprofit, Catalyst4, is the drug developer’s largest shareholder, and two leaders of his family office sit on the board, including one of MapLight’s co-founders. The nonprofit currently controls a 60.7% majority voting stake in MapLight, although that is expected to decline to 36.8% after the IPO, according to filings.
