Retirement comes 25 years after founding BlackLine
Will remain on the Board of BlackLine
LOS ANGELES, March 24, 2026 (GLOBE NEWSWIRE) -- BlackLine, Inc. (Nasdaq: BL) announced today that industry visionary Therese Tucker, the Company’s founder and largest individual shareholder, will retire from full-time executive employment with the company effective June 2, 2026. Ms. Tucker, who owns approximately 8 percent of BlackLine’s total outstanding shares, will remain actively engaged with the Company as a board member and significant shareholder.
“Founding BlackLine and watching it grow into the global platform that it is today has been the privilege of my professional life,” said Ms. Tucker. “I stepped back into a management role alongside Owen at an important inflection point for the Company, and at a time when our industry was evolving rapidly. The board of directors and management team shared a vision of transforming BlackLine from a product-focused vendor into a true platform partner for the Office of the CFO. Since that time, we have launched our Studio360 platform, innovated our product portfolio, especially our industry-leading AI capabilities, and refined our go-to-market strategy, by focusing on the highest value customer opportunities. The success of this strategy is now beginning to be demonstrated in our results, and I believe that it is the right time for me to take a step back from the day-to-day of BlackLine. With Owen at the helm, a deep bench of talent across our leadership team, and an active and engaged board of directors, I have absolute confidence in BlackLine’s future. I remain strongly committed to BlackLine, and I look forward to continuing to serve on the board of directors. I am incredibly optimistic about the opportunities in front of BlackLine.”
“Therese isn’t just the founder of BlackLine; she is the architect of the modern accounting category. Her vision has paved the way for us to deliver the Studio360 platform, which is transforming finance operations for companies worldwide,” said Owen Ryan, CEO of BlackLine. “The leadership team will carry her legacy forward by continuing to drive innovation and deliver on our promise to be the most trusted partner for the Office of the CFO.”
