Imagine being fresh out of college, excited about your dream job, only to discover something shady going on behind closed doors. That’s exactly what happened to Erika Cheung, a name you might not know yet but definitely should. She’s a real-life hero who stood up against a massive biotech scam at Theranos, a company once valued at billions of dollars. Today, Erika’s story isn’t just about exposing lies it’s about courage, ethics, and making the world a better place for startups and innovators. Let’s dive into who Erika Cheung is, what she did, and why her journey matters to all of us.
Who Is Erika Cheung?
Erika Cheung is an American entrepreneur, public speaker, and whistleblower who became famous for her role in uncovering the truth about Theranos, a biotech company that promised to revolutionize healthcare but ended up being a fraud. Born in Los Angeles, California, Erika grew up with a passion for science and helping people. She was homeschooled for most of her early years, started community college at just 14, and later earned two degrees from the University of California, Berkeley one in Linguistics and another in Molecular and Cell Biology. That’s a pretty impressive start for someone who would later shake up the tech world!
After graduating in 2013, Erika landed her first big job at Theranos, a company led by Elizabeth Holmes. At the time, Theranos was a Silicon Valley darling, claiming it could run hundreds of medical tests with just a single drop of blood. It sounded like magic, and Erika was thrilled to be part of it. But what she found inside the company wasn’t magic it was a mess. And that’s where her story takes a wild turn.
The Theranos Scandal: What Went Wrong?
Theranos was supposed to be the future of medicine. Elizabeth Holmes, the company’s founder, convinced big investors, famous people like Henry Kissinger, and even Walgreens that her tiny blood-testing machine, called the Edison, could change lives. The problem? It didn’t work. Erika, hired as a lab assistant, started noticing red flags almost right away.
About a month into her job, Erika was asked to run quality control tests on patient samples. These tests are super important they make sure the results are accurate before they go to doctors and patients. But the Edison machine kept failing. Over and over again. Erika remembers working alone in the lab on Thanksgiving Day, panicking because the system wouldn’t give reliable results. She called a helpline for support, but even after resetting everything, it still didn’t work. She thought, “How can we send these results to patients if they’re wrong?”
As time went on, Erika saw more problems. The machines weren’t just glitchy they were wildly inaccurate. Test results for serious conditions like cancer or thyroid issues could be way off, which could trick doctors into giving people the wrong treatment or no treatment at all. She tried talking to her bosses, but they didn’t want to hear it. Theranos cared more about looking good to investors than fixing the science. That’s when Erika realized something big: this wasn’t just a mistake it was a cover-up.
Becoming a Whistleblower: A Tough Choice
Erika wasn’t alone in noticing the chaos. She teamed up with another employee, Tyler Shultz, whose grandfather was a Theranos board member and former U.S. Secretary of State, George Shultz. Together, they started collecting proof data showing how bad the machines really were. They compared Theranos results to standard lab tests and found huge differences. For example, a cancer marker might show up three times higher or lower than it should. That’s not a small error that’s life-or-death stuff.
But speaking up wasn’t easy. Erika was only 22, fresh out of school, and this was her first real job. She didn’t want to ruin her career before it even started. Plus, Theranos was powerful. They had lawyers, money, and a reputation for crushing anyone who got in their way. When Erika and Tyler tried to warn people inside the company, they got ignored or told to keep quiet. Eventually, Erika couldn’t take it anymore. She quit in 2014 and decided to tell the truth.
She reached out to health regulators and shared what she knew. Later, she connected with John Carreyrou, a journalist from The Wall Street Journal, who wrote a bombshell article in 2015 exposing Theranos. That article sparked investigations, lawsuits, and the company’s downfall. Elizabeth Holmes faced criminal charges, and Theranos shut down its labs, all because Erika and a few others had the guts to speak out.
Life After Theranos: Building a New Path
You might think blowing the whistle on a billion-dollar company would break someone, but Erika turned it into a superpower. After Theranos, she moved to Hong Kong and worked with Betatron, a tech accelerator that helps startups grow in Asia. She wanted to support innovation the right way by making sure it’s honest and safe. But her experience at Theranos stuck with her. She kept thinking: how can we stop this from happening again?
That’s when Erika co-founded Ethics in Entrepreneurship, a nonprofit she now runs as Executive Director. The idea is simple but powerful: help startups build ethical habits from the start. Whether it’s being honest with investors, treating employees fairly, or making products that actually work, Erika’s mission is to create a tech world where doing the right thing isn’t optional it’s normal. She speaks at events, advises companies, and even helps connect businesses between the U.S. and Asia, all while pushing for better standards in biotech and healthcare.
Why Erika’s Story Matters Today
Erika Cheung’s journey isn’t just a juicy scandal it’s a wake-up call. Startups are everywhere now, promising to fix everything from climate change to healthcare. But hype can hide the truth. Theranos showed us how easy it is for a company to trick people when no one asks hard questions. Erika’s bravery reminds us that regular people—like a 22-year-old lab assistant can make a huge difference by standing up for what’s right.
Her work with Ethics in Entrepreneurship is also a game-changer. Startups often move fast, chasing money and growth, but Erika wants them to slow down and think: Are we helping or hurting? She’s not against innovation she loves science and progress but she knows it has to be real. In a way, she’s protecting the dreamers, the patients, and even the investors who got burned by Theranos.
Where Is Erika Cheung Now?
As of April 2025, Erika is still based in Los Angeles but spends time traveling for work. She’s a busy woman running her nonprofit, speaking at conferences, and advising biotech companies. She’s also become a bit of a celebrity in her own right. Her story inspired books like Bad Blood by John Carreyrou, documentaries like The Inventor: Out for Blood in Silicon Valley, and even a Hulu series called The Dropout, where actress Camryn Mi-Young Kim plays her. Erika’s even testified in court against Elizabeth Holmes, helping seal the case that sent Holmes to prison.
On a personal level, Erika keeps things private. She’s shared some tough stuff about her past like surviving sexual assault as a kid, which led to panic attacks but she doesn’t talk much about her family or love life. There’s no word on a husband or boyfriend, though she’s posted about her longtime friend Jeffrey Gomez. For now, it seems like her focus is 100% on her mission.

Erika Cheung vs. Elizabeth Holmes: A Tale of Two Paths

Holmes wanted fame and billions; Erika wanted facts and fairness. One ended up in jail, the other became a role model. It’s like a real-life movie where the underdog wins not with power, but with principle.
How Erika’s Work Shapes the Future

Erika’s pushing for a world where those ideas get checked not to stop them, but to make them stronger. Her nonprofit offers tools and advice so founders don’t repeat Theranos’ mistakes. She’s also big on “speak-up culture,” where employees feel safe calling out problems. That could mean fewer flops and more wins for everyone.
Plus, Erika’s bridging gaps between the U.S. and Asia, helping biotech grow in places like Hong Kong and China. She’s not just fixing the past she’s building a better future.
