Marketo Announces Leadership Changes in Finance, Administration, and Operations

SAN MATEO, Calif. — March 7, 2016 — Marketo Inc. (NASDAQ: MKTO), the leading provider of engagement marketing software and solutions, today announced the appointment of Fred Ball to executive vice president and chief administrative officer (CAO), effective immediately. In addition, Brian Kinion was promoted to senior vice president and chief financial officer (CFO), and Jason Holmes was promoted to executive vice president and chief operating officer (COO). All three will report to Chairman and CEO Phil Fernandez.

Ball, who has been CFO since May 2011, led the company through its successful IPO in May 2013 and oversaw Finance and Accounting through a period of rapid growth and change, as Marketo’s revenue grew from $14 million in 2010 to $210 million in 2015. As CAO, Ball will continue to lead Marketo’s Global Corporate Development, Corporate Strategy, and Information Technology and Facilities teams. Central to his role will be leading the company’s strategic planning as the business continues to scale to meet the needs of enterprise companies.

As CFO, Kinion will be responsible for global financial reporting and compliance, financial planning and analysis, investor relations, and driving continuous process and system improvements to support the company’s growing operations. Kinion, who was previously group vice president of finance, brings more than 25 years of finance and accounting experience, and nine years of SaaS experience.

Taking on the role of COO, Holmes, who was previously chief customer officer, will expand on his current role to drive Marketo’s broad growth initiatives across the entire company. This role is a key addition to the executive team that will unify management of strategy, execution, and accountability of the entire organization as Marketo continues to grow.

“I am thrilled to see Fred, Brian and Jason take these next steps in their careers,” said Fernandez. “Fred has been an integral member of our senior leadership team and has made countless contributions to Marketo’s success. The rate of growth and pace of change at Marketo has necessitated this position, and no one is more capable of fulfilling the responsibilities of this role than Fred. At the same time, it is incredibly gratifying to promote Brian to CFO. Fred and I identified him nearly three years ago as a future CFO candidate, and I’m confident that he will be a great CFO for Marketo. I am also pleased to see Jason step into the new role of COO. His deep understanding of what makes our customers successful will be invaluable as we continue to grow. I am incredibly confident in the senior leadership team we’ve built for the next phase of our growth, and I’m excited that this additional operating strength on my staff will allow me to focus more of my time on Marketo’s strategic vision and our most important customer and partner relationships.”
