Westly was an investor and board member of the adtech firm RadiumOne, whose founder, Gurbaksh Chahal, was charged with domestic violence and eventually pled guilty to two misdemeanor counts. Westly agreed that Chahal should pay former San Francisco mayor Willie Brown a $250,000 retainer to provide legal representation in order pursue a legal settlement with the district attorney. In a meeting with Chahal, Brown said his legal services may cost upwards of $1 million. After the video of the incident was ruled inadmissible, Brown returned $198,400 of the initial retainer. The RadiumOne board fired Chahal after he pled guilty.
