History

BlackLine was founded in 2001 by Therese Tucker, a former CTO at SunGard Treasury Systems.[7][8][9] The initial goal was to help customers replace their use of Excel with a suite of accounting software.[10]
The company functioned with no outside funding until 2013 when the private equity firm, Silver Lake Partners invested more than $200 million in the company.[11][10]
BlackLine reached an agreement to form a strategic alliance with the financial consulting firm McGladrey, in 2015. As part of the alliance, the companies began offering a business process as a service (BPaaS) platform.[12]
The company's IPO was October 28, 2016; they're listed on the Nasdaq under the symbol BL. [13][14]
