Prior to his stint with the developer, he spent nine years as a managing director at Allen & Co.<br /><br />Facebook Co-Founder and CEO Mark Zuckerberg addressed Ebersman’s departure in the earnings release:<br /><br />David has been a great partner in building Facebook, and I’m grateful for everything he’s done to help make the world more open and connected. David set us up to operate efficiently and make the long-term investments we need, and he built an incredibly strong team, including Dave Wehner, our next CFO. I look forward to working with Dave in his new role.<br /><br />Ebersman added:<br /><br />This has been a tough decision because Facebook is such a great company and has such a bright future ahead, but I’ve decided to move back into healthcare, where I spent my career before Facebook. It’s been a privilege working at Facebook and being part of such a great team. We have an incredibly talented finance organization, and I have complete confidence in Dave Wehner and his ability to lead the team going forward.
