About Partin Mark

Mark Partin served as Chief Financial Officer of BlackLine, Inc. for nearly a decade, retiring effective March 1, 2025. At BlackLine, a U.S.-listed software company focused on financial close and accounting automation, he played a central role in building the finance function, preparing the business for the public markets, and strengthening the company’s financial controls and operating discipline. BlackLine states that he joined the company in January 2015 and also served as Treasurer. His tenure was closely associated with the creation of a best-in-class finance organization designed to support growth, efficiency, and governance at scale. One of the most notable milestones during his time at BlackLine was the company’s preparation for its Nasdaq Global Select Market debut in October 2016. BlackLine highlighted his leadership in readying the business for that transition, emphasizing the importance of strong internal controls, finance process rigor, and a public-company-ready operating model. The company later recognized him publicly for the work involved in guiding BlackLine through its first years as a listed company, as well as for helping establish finance practices that supported growth and improved efficiency. In 2017 and again in 2018, Partin received recognition from the San Fernando Valley Business Journal, including being named “CFO of the Year.” Those honors reflected his role in leading BlackLine’s finance organization through a major period of transformation, from a high-growth private software company to a public enterprise with broader reporting, compliance, and governance demands. BlackLine also credited him with helping create a finance team capable of supporting the company’s expansion and operational maturity. Beyond BlackLine’s own acknowledgments, Partin’s profile is that of a seasoned finance executive with prior senior financial roles before joining the company. While publicly available details on his earlier career are limited in the sources reviewed, BlackLine’s materials indicate that he brought substantial experience in corporate finance and accounting leadership. His work has been tied to themes that are highly relevant in corporate governance: disciplined financial reporting, internal control enhancement, risk reduction, and support for strategic growth. Overall, Mark Partin is best understood as a finance leader who helped guide BlackLine through a critical governance and capital-markets phase. His contribution was less about public-facing corporate strategy and more about building the financial infrastructure and controls that allow a technology company to grow responsibly as a listed issuer.
