Katie Haun: From Prosecuting Crypto Crime to Driving Blockchain Innovation

Katie Haun’s career is a narrative of transformation — from a federal prosecutor navigating the murky waters of cryptocurrency-related crime to a trailblazing venture capitalist leading billion-dollar investments in blockchain innovation. Her unlikely journey highlights not only her adaptability but also the broader evolution of cryptocurrency from a misunderstood technology to a driving force in the global economy.


The Assignment That Changed Everything

In 2012, as a federal prosecutor with the U.S. Department of Justice (DOJ) in San Francisco, Katie Haun was handed a case that would change her life: investigate bitcoin. At the time, cryptocurrency was largely associated with cybercrime and illicit activities, such as those tied to Silk Road, the infamous darknet marketplace. Haun approached the assignment with the same meticulous diligence she had applied to cases involving organized crime and prison gangs.

“The more I did some diligence and looked into it, I found that some of the myths I’d been hearing were just not true,” Haun later explained. The technology that many viewed as an enabler of crime, she discovered, was also a tool for transparency. Blockchain’s immutable record — often called “digital breadcrumbs” — made it easier to trace illicit transactions than cash.

It was this revelation that shifted Haun’s perspective on cryptocurrency from skepticism to curiosity. What began as an assignment became a passion, as she realized the transformative potential of blockchain to revolutionize not only finance but also how trust is established in digital transactions.


From the Courtroom to Cryptocurrency Advocacy

During her decade at the DOJ, Haun earned a reputation for tackling complex cases involving cybercrime and corruption. She founded the government’s first cryptocurrency task force and led high-profile investigations into issues such as the Silk Road task force corruption scandal and the collapse of Mt. Gox, once the world’s largest bitcoin exchange.

Through her work, Haun gained an insider’s understanding of cryptocurrency’s duality: while it could be misused, it also had unparalleled potential for transparency and innovation. “If you’re a good criminal, bitcoin or cryptocurrency is one of the last things you should use,” she noted, highlighting how blockchain’s traceable nature often worked in law enforcement’s favor.

Her nuanced perspective caught the attention of Marc Andreessen and Ben Horowitz, founders of the venture capital firm Andreessen Horowitz (a16z). At a time when many VCs were still wary of blockchain, the duo saw in Haun a unique blend of regulatory expertise and forward-thinking vision. In 2018, Haun joined a16z as its first female general partner, co-leading the firm’s crypto investments alongside Chris Dixon.


Building the Crypto Future at a16z

At Andreessen Horowitz, Haun helped grow the firm’s crypto team from a modest two-person operation into a robust group of 50. Together, they championed investments in blockchain projects that pushed the boundaries of what the technology could achieve.

Haun’s time at a16z wasn’t just about supporting crypto startups; it was also a period of personal discovery. “One of the things I learned in the last four years at the firm is I’m actually an entrepreneur,” Haun said. This self-awareness laid the foundation for her next career leap.

In December 2021, Haun announced her departure from a16z to launch her own venture capital firm. The move underscored her growing influence in Silicon Valley and the crypto industry, as well as her confidence in blockchain’s long-term potential.


Launching a $1 Billion Crypto Fund

Katie Haun’s new firm, Haun Ventures, set out with an ambitious goal: raise $1 billion to invest exclusively in crypto-related projects. The announcement sent shockwaves through the venture capital world, not only because of the fund’s size but also because of the conviction Haun displayed in a market that many considered volatile.

Her strategy extended beyond traditional tech investments. By assembling advisers from technology, government policy, and entertainment, Haun aimed to address crypto’s growing influence across multiple industries. She also focused on fostering global innovation, recognizing that the next wave of blockchain disruption would likely emerge from diverse corners of the world.

“I think some of the best crypto founders are going to be found all over the globe,” she explained. “There are so many more use cases than we imagined back then.”


Facing Challenges in a Turbulent Market

The timing of Haun’s independent venture hasn’t been without its hurdles. The crypto market has faced significant volatility, with dramatic price swings and increasing regulatory scrutiny. However, Haun’s background as a federal prosecutor gives her a unique perspective on managing uncertainty and navigating regulatory challenges.

“The nature of running a crypto fund is taking on risk,” she noted. Drawing parallels to her legal career, Haun emphasized her ability to evaluate people and situations under pressure. “That’s what I did for a living for over a decade. I made deals, I negotiated, I sat opposite someone on the other side of the table that I had to suss out quickly.”

Her experience has proven invaluable in the unpredictable world of cryptocurrency, where understanding the nuances of regulation and risk is crucial.


Educating Critics and Building the Future

Haun is no stranger to skepticism, particularly from those who view cryptocurrency as a passing fad or a tool for criminals. Her response to these critiques is rooted in her deep knowledge of the space and its transformative potential.

“We are in the dial-up days,” Haun said, likening blockchain’s current state to the early days of the internet. “The critics out there confuse the current state of innovation with the end state of the innovation.”

She acknowledges that early cryptocurrencies like bitcoin were “slow” and “clunky” but believes the technology has since matured. Innovations like stablecoins and energy-efficient consensus mechanisms demonstrate how far the industry has come — and how much further it can go.


Beyond Finance: Crypto’s Expanding Horizons

One of Haun’s most compelling arguments for crypto’s future is its potential beyond financial applications. From decentralized identity solutions to blockchain-based governance systems, the technology’s use cases are expanding rapidly.

“Now, in my new position as a venture capitalist, I see teams every week coming from engineering teams, coming from Google, or developer teams coming from Facebook,” Haun shared. “These people are leaving stable jobs to pursue something they believe in deeply.”

Her optimism is bolstered by the passion and innovation she encounters in the space. For Haun, these developments signal that blockchain is not just a financial tool but a foundation for the next wave of technological progress.


A Symbol of Crypto’s Maturity

Katie Haun’s journey from investigating bitcoin as a federal prosecutor to becoming one of its most prominent advocates mirrors the evolution of cryptocurrency itself. What began as a niche, misunderstood technology has grown into a global force reshaping finance, governance, and beyond.

As Haun continues to invest in crypto’s future, she remains committed to educating skeptics, supporting innovators, and pushing the boundaries of what blockchain can achieve. Her story is a testament to the power of curiosity and adaptability — and a reminder that the future often belongs to those willing to embrace the unknown.
