Michael Cieri, Executive Vice President, General Manager of Software Solutions, has been promoted to Chief Product Officer. In this expanded role, Cieri will lead all product management, product marketing, design, research, and product strategy.
With this appointment, Cieri will oversee the newly created Product Organization, bringing together software solutions, payments, and financial services under unified leadership. This structure reflects how customers use BILL's software and payments capabilities together across a single, integrated platform. By bringing these functions together, BILL is positioned to move with greater speed and drive more integrated customer experiences.
Ken Moss, who has served as Chief Technology Officer since 2023, will depart BILL. Moss led BILL's engineering organization through a pivotal period of transformation, including the development of the company's AI platform, while streamlining and accelerating the company's ability to deliver impactful innovation for customers. Moss will move to an advisory role where he will continue to contribute his AI expertise to BILL and support a seamless transition.
Eric Chan, Distinguished Engineering Fellow at BILL, has been appointed CTO. Chan, who was the company's founding engineer and first CTO, has served on the company's engineering executive team for nearly 20 years. Chan will lead BILL's AI platform strategy and execution as we scale through this next phase and expand the company's AI capabilities.
President and Chief Operating Officer John Rettig, who has been with BILL for more than a decade, will step into the newly created role of Chief Strategy and Transformation Officer. Rettig has helped scale the organization during his tenure, and will maintain oversight of the company's operational execution, while focusing on enterprise strategy, transformation, and long-term growth initiatives.
Sarah Acton, Chief Customer Officer, will depart BILL after almost five years on the executive leadership team. As CCO, and formerly as Chief Marketing Officer, Acton unified BILL's global go-to-market strategy, drove growth, elevated the customer experience, and led the transformation of BILL's brand in the market. BILL expects to announce a new Chief Revenue Officer in the coming weeks.
Mary Kay Bowman, Executive Vice President and General Manager of Payments and Financial Services, will depart the company. Bowman joined BILL in 2024 and made a significant impact on the business. During her tenure, Bowman strengthened, expanded and modernized BILL's payments and financial services capabilities, and led strategic initiatives including Supplier Payments Plus and BILL Cash Account from concept to reality. Bowman will continue to support BILL as an advisor.
"I'm excited to welcome Eric to the BILL executive leadership team, and congratulate John and Michael on their expanded roles. Their experience and leadership will help us continue shaping the future of intelligent finance for the Fortune 5 Million," said Lacerte. "I'd like to also sincerely thank Sarah, Ken and Mary Kay for their contributions to BILL and the impact they've had on our company, customers and teams over the years. We are grateful for everything they have helped us build and accomplish, and we wish them continued success in their next chapters."
