Poppy Alexander is a partner at Whistleblower Partners. She represents whistleblowers in a variety of industries and under all the whistleblower programs, including the False Claims Act and the whistleblower programs administered by the Department of Treasury, SEC, CFTC, IRS, and Department of Transportation.

Poppy specializes in matters concerning cutting edge financial frauds, including money laundering, Bank Secrecy Act, cryptocurrency, and Foreign Corrupt Practices Act matters.

She was actively involved in the creation and expansion of the FinCEN Whistleblower Program and continues to push the boundaries of financial fraud whistleblower work. Poppy also has a strong background in human rights law, and she seeks out whistleblower cases that can help promote corporate accountability for human rights abuses around the world.

“My whistleblower clients are all extraordinary people – willingly coming forward to stand up for what’s right. It is such an honor to get to work with them every day. ”

Poppy graduated from Harvard Law School in 2012. She was the co-editor-in-chief of the Harvard Civil Rights-Civil Liberties Law Review and an active participant in the Human Rights Clinic, working on issues related to corporate accountability for human rights violations in Africa and military abuses in Southeast Asia. She was awarded the Dean’s Award for Community Leadership in recognition for her contributions to the school community. Poppy was named to the Super Lawyers Rising Stars list every year from 2016 to 2023.

Prior to law school, Poppy worked on election reform issues before beginning graduate work at the University of California, Berkeley, where she studied political and critical theory. 

Outside of work, Poppy enjoys teaching her two kids to bake and ski and cajoling her dog up the many hills of San Francisco. 


  • A False Claims Act case concerning a decade-long conspiracy by the five largest oil companies in South Korea to rig their bids to artificially inflate prices on fuel contracts for U.S. military bases in South Korea. Poppy and her colleagues helped the government recoup over $360 million in fines and penalties to settle the case. The settlements were the largest in American history under Section 4A of the Clayton Act and helped spur the creation of the Department of Justice’s Procurement Collusion Strike Force (PCSF).

  • The first-ever whistleblower award made by the National Highway Traffic Safety Administration, the federal auto-safety regulator. In 2021, Poppy and her colleagues secured a $24.3 million reward for a former Hyundai safety engineer, whose information concerning engine safety failures led the agency to impose a combined penalty on Hyundai and Kia totaling $210 million.

  • Representing Frances Haugen in her fight to expose Meta’s lack of safety protocols, contributing to dangerous political upheaval and child safety concerns around the globe.

  • Some of the first cases against major U.S. banks filed under the new FinCEN Whistleblower Program concerning serious violations of the Bank Secrecy Act through the banks’ systematic compliance failures.
