Snap Inc. quickly hired Michael O'Sullivan to lead the company's legal department, just weeks after the previous GC, Chris Handman, notified employees about his departure. O'Sullivan, who represented giants such as Google Inc. and Bank of America earlier in his career, joins the company behind popular messaging app, Snapchat, from Munger, Tolles & Olson, where he was a partner.

Snap did not return a message seeking comment, and a call to O'Sullivan's number at his old firm was not returned.

A Snap representative did confirm O'Sullivan's hire for a Business Insider report, along with two separate new hires. According to the report, Snap hired Kathy Mandato as the new vice president of human relations and Francis Racioppi Jr. as the new director of global security. Business Insider also reported that Robyn Thomas, former vice president of human resources and legal, recently left the company.
