Zoom to Acquire Five9 to Build the Customer Engagement Platform of the Future

[View in Browser]( | [Forward to a Friend]() [Five9, Inc.]() Dear {NAME}, By now you’ve probably heard the news that Zoom and Five9 are combining forces [() For me, as well as the rest of the Five9 team, this is an incredibly exciting time and opportunity. The UCaaS and CCaaS spaces have always been synergistic, and we believe combining Five9’s CCaaS solution with Zoom’s broad communications platform will transform how enterprises engage with their customers, building the customer engagement platform of the future. At the same time, I want you to know that we remain 100% committed to our vision of providing a world-class, industry-leading intelligent cloud contact center to support your needs. I know Zoom’s CEO Eric Yuan well, and also know that our companies share much in common. Like us, Zoom is maniacally focused on their customers, has a great corporate culture and is committed to doing business the right way. Once the transaction has closed, we believe the newly combined company will create an even stronger communication and customer engagement solution for our customers, as well as enabling higher levels of investment in growth areas, while maintaining a stable platform for the mission-critical software that our customers rely on. We know that you will have questions and our goal is to be as transparent as possible and ensure those questions get answered throughout the coming months as we work towards closing the transaction. In the meantime, it’s business as usual and we remain two separate companies operating independently. You can send any questions that you may have to questions@five9.com or reach out to me directly at rowan@five9.com. Your account rep or CSM should be reaching out to you. We look forward to continuing our partnership with you as a valued customer. ROWAN CEO, Five9 P.S. As required by law, please see this important legal notice below.
