About Zinn Matthew
Matthew Zinn most notably served at 8x8, Inc. as Senior Vice President, General Counsel, Secretary and Chief Privacy Officer beginning in September 2018, and later as Chief Legal Officer, Secretary and Chief Privacy Officer until his departure in December 2022. His 8x8 tenure reflects a senior legal and governance leadership track within a U.S.-listed cloud communications company. In that role, he oversaw legal, privacy, compliance, and corporate secretarial functions, with direct responsibility for corporate governance matters and regulatory risk management. ([investors.8x8.com](https://www.investors.8x8.com/node/6371/html?utm_source=openai)) Before joining 8x8, Zinn held senior legal leadership roles at TiVo Inc., where he served as Vice President, General Counsel, Chief Privacy Officer, and Corporate Secretary for an extended period. His earlier background also included senior legal positions at MediaOne Group Inc. and Continental Cablevision, as well as practice experience with the law firms Cole, Raywid & Braverman and Fisher, Wayland, Cooper & Leader. This mix of in-house and law-firm experience gave him deep exposure to corporate law, privacy, compliance, and board-level governance. ([investors.8x8.com](https://www.investors.8x8.com/node/6371/html?utm_source=openai)) At 8x8, he would have been closely involved in governance processes, public-company disclosures, and the legal oversight required of a Nasdaq-listed business operating in a fast-moving technology sector. His remit likely included supporting board and executive actions, privacy-related controls, and compliance obligations as the company continued its evolution in cloud communications. Available sources indicate that he left 8x8 in December 2022 to take a Chief Legal Officer role at another publicly traded company in a different industry.
