Jonathan Levin’s friend Tom had a suggestion: they should write a trading bot. It would exploit price differences between two Bitcoin exchanges, Bitstamp and Mt. Gox. Levin had a more basic question. Where, exactly, was Mt. Gox? In 2012, sitting in a pub as an Oxford graduate student, he was encountering a financial system whose vocabulary had arrived before its explanation.
There are several respectable ways to leave such a conversation. Order another drink. Change the subject. Levin went looking for the mechanism. He read Bitcoin forums, joined technical discussions and began studying the incentives behind the currency. The pub proposal grew into an academic problem, then a business problem. A dozen years later, he would become CEO of Chainalysis, the company he helped found to make cryptocurrency activity understandable.
The question that followed him was wonderfully inconvenient: what are people actually doing with this money? A technology can announce its intentions at considerable volume. Its transactions tell a different kind of story, provided someone can read them.
The economist before the detective
Levin’s training began with economics at Bristol, where he graduated with first-class honours, followed by an MPhil at Oxford between 2012 and 2014. His master’s thesis examined Bitcoin as a decentralized payment system. He also worked as a research assistant to economist Ian Goldin. These were questions about how markets function, which incentives hold them together and what happens when their rules change.
His interests extended beyond university seminars. He convened the Oxford Virtual Currencies Working Group, bringing different disciplines into the same discussion. He developed early statistical work on Bitcoin transaction fees. At a time when the currency invited sweeping declarations, fees offered something more usefully specific: a price attached to getting something done.
There was an earlier commodity in the picture, too. In congressional testimony, Levin described studying the effect of speculators on copper prices and visiting the London Metal Exchange. Copper and Bitcoin make an odd couple. One can be delivered in substantial physical quantities; the other is unlikely to require a loading bay. Both invite questions about price discovery, market structure and the institutions that let strangers transact.
That connection helps explain the economist’s route into crypto. A market needs more than enthusiastic participants. It needs ways to establish what is happening, evaluate risk and respond when someone abuses the arrangement. Levin’s work increasingly occupied that practical territory.
First, learn to count
Before Chainalysis came Coinometrics. Levin co-founded the digital-currency analytics business and served as CEO from September 2013 to November 2014. Its work concerned measuring activity and providing risk tools for a payment system still establishing its place. The subject already contained the ingredients of his later career: transactions, interpretation and customers who needed something sturdier than a theory.
It is easy to give a founder’s first company the role of a dress rehearsal. Coinometrics deserves a more precise place in this story. Levin was already attempting to turn knowledge about cryptocurrency into a usable service. The underlying curiosity had acquired a customer. That change matters: research can end with a better question; a customer usually wants something that works on Tuesday.
Chainalysis was co-founded in 2014 by Levin, Michael Gronager and Jan Møller. The company brought blockchain analysis to institutions confronting digital money. Its customers would include cryptocurrency businesses, financial institutions and government agencies. The range of audiences became part of the challenge. The same transaction could be a compliance concern, an investigative lead or an entry in a much larger market picture.
The pipes beneath the promise
Levin’s early personal writing offers a glimpse of how he approached explanation. He described Bitcoin through pipes: a growing network of transactions whose earlier configurations could be examined. The analogy made the system less ethereal. A payment had a path. The network had a history. There was something to inspect after the excitement had subsided.
He also wrote about scarcity, sidechains and the currencies that emerge inside virtual worlds. His attention moved between the design of a system and the behavior it produced. A rule set could encourage a market. A market could develop habits its designers had never planned. The economist was still present, peering through the machinery.
In a 2018 conversation with Laura Shin, Levin explained how patterns in transactions could help connect addresses to wallet software, and how information about services could add context. That explanation carries an essential distinction: seeing a transaction and understanding its participants are separate tasks. A public ledger does not arrive with every useful label attached. There is a business in the labeling, and a responsibility in getting it right.
A soft landing in New York
Chainalysis went through the Barclays accelerator powered by Techstars in New York. For Levin, who had moved from London, the program connected the young company with a financial institution and a network of people who could help it grow. Years later, he would credit Jenny Fielding with opening doors during that period. Company-building, even in a field devoted to decentralization, remained a thoroughly social activity.
His conversations with Techstars co-founder David Cohen returned to company values and the practice of giving help. Another conversation, with Auren Hoffman in 2022, explored the difficulty of building a data business and why it can be misunderstood through the familiar lens of software subscriptions. The product depended on accumulated understanding, as well as the interface through which customers reached it.
Government customers introduced their own lessons. In a March 2026 interview, Levin recalled early buyers using expense credit cards to purchase Chainalysis. It is a pleasingly ordinary detail in an industry with a taste for extraordinary numbers. Someone had a job to do, found a tool and worked out how to buy it. Demand occasionally announces itself in the accounts department.
“I’d never spoken to a cop before I actually started Chainalysis.”
Jonathan Levin, reflecting on the company’s beginnings, 2025
The remark is a useful corrective to the idea of a founder arriving fully formed. Levin’s subject took him into unfamiliar professional worlds. An economist studying a new payment system found himself explaining its traces to people investigating crimes. The expertise had to grow in both directions.
A seat before Congress
By June 2017, Levin was testifying before a House subcommittee on terrorism and illicit finance. His written remarks connected his earlier research on Bitcoin’s incentives to the practical work of identifying illicit cryptocurrency use. The audience was no longer a working group at Oxford. The questions concerned financial innovation and national security.
He returned to congressional hearings in subsequent years. His 2023 testimony described the possibility of using blockchain transactions to uncover networks across borders. In July 2025, appearing as CEO before the Senate Banking Committee, he argued for approaches that used the technology’s transparency while addressing abuse. His public position gave a continuing role to institutions that some cryptocurrency enthusiasts had once hoped to bypass.
That is a demanding position to explain. Cryptocurrency promises wider access; institutions require controls. Investigators need information; analytical claims need scrutiny. Levin’s career places him among those trying to make these requirements coexist in actual products and actual markets. The tension provides plenty of work. A slogan would have a much easier schedule.
Ten years before the corner office
Levin became CEO effective December 3, 2024. The appointment followed years as chief strategy officer and work across sales, marketing, corporate development, policy and research and development. He had learned the company through several of the functions a chief executive must connect.
The new job also meant explaining a widening ambition. At Links NYC in 2025, he discussed fraud prevention and smart-contract security alongside the company’s investigative work. Chainalysis had acquired Hexagate and Alterya. The direction extended the familiar task of following money toward identifying danger earlier.
During the same conference, Levin spoke with Tether CEO Paolo Ardoino about stablecoins and their role in the financial system, including emerging markets. It was another version of the question that had followed him since university: how do people use this technology? The answer now involved established financial businesses as well as early Bitcoin experiments.
The next investigation has an AI assistant
On March 31, 2026, Levin introduced Chainalysis blockchain intelligence agents. The announcement described tools for investigations and compliance, with a summer rollout planned. It emphasized data quality, context, auditability and human control. Those are consequential requirements when an output may shape an investigation or a financial decision.
“Chainalysis is the harness,” he wrote. The image suits a founder whose work has repeatedly involved connecting a powerful technology to practical constraints. An assistant can accelerate research, enrich an alert or draft a report. People still need to examine the reasoning and understand the record behind a conclusion.
The organization was changing alongside the tools. Sebastien Giroux joined as CFO in February 2026. In July, the Finisterra team announced it was joining Chainalysis, bringing experience in distributed systems, cryptography and data infrastructure. These developments put people and operating capacity behind the product agenda.
By October 2026, he was discussing sanctioned states, illicit cryptocurrency flows and AI-enabled threats in a new interview. The subject had expanded again. Payment networks were entangled with geopolitics, while automation was changing the tools available to criminals and investigators alike. The original research question now carried a much longer list of consequences.
Levin’s path began with a suggestion about exploiting a price difference. It led him toward the harder problem of understanding a financial system well enough for other people to rely on that understanding. The money became easier to move. His career has unfolded around everything that must happen after it moves, and increasingly before it disappears.
