He uncovers Kremlin assassins with open-source sleuthing and finds himself hunted by the regime he exposes.
Christo Grozev is the kind of journalist who treats reality like a puzzle, one assembled from social posts, flight logs, leaked documents, and CCTV stills. With patient precision, he traces the trail of assassins, spies, and chemical weapons, packaging them into public narratives so exact and consequential that Kremlin officials have declared him a target. The man who named the Salisbury poisoners now bears a Russian arrest warrant, a stark sign that his quiet craft threatens the world’s most dangerous secrets.
Yet Grozev does not see himself as a crusader. A former media executive turned investigative reporter, he applies the same analytical rigor to open-source evidence as he once did to broadcasting strategy. His strength lies not in rhetorical flourish but in forensic attention to tiny details, an unexpected quality in someone thrust, unwillingly, into the limelight. His method is not ideological; it relies on processes that can be tested, repeated, and verified.
It is this blend of rigor and restraint that has made him indispensable and endangered. Few journalists have managed to expose conspiracies at the heart of the Kremlin with such calm clarity. And while his name now rings alarm bells in Moscow, his work is reshaping journalism itself, turning social media into a global courthouse and open data into the new truth regime.
From Radio Mogul to Kremlin Tormentor
Christo Grozev was born on May 20, 1969, in Plovdiv, Bulgaria. His early career was in radio: he co-founded Bulgaria’s first private station, later managed media assets across Eastern Europe, and eventually became a regional director for Metromedia’s broadcasting networks. By his mid‑forties, he had built—or sold—radio empires under his own name.
Yet a deeper calling emerged in 2015, when Grozev joined Bellingcat, an open-source investigative collective. He quickly became lead Russia investigator, deciphering digital breadcrumbs to expose clandestine operations. His report identifying the three Russian GRU officers behind the novichok poisoning of Sergei and Yulia Skripal in 2018 earned him the European Press Prize and global attention.
Grozev’s transformation from media entrepreneur to activist‑scholar is a study in paradox. He did not enter journalism to fight authoritarianism, but once his investigations began to bleed into prosecution and international tribunals, he discovered that the institutional respectability of radio broadcasting offered little protection against state wrath.

From Salisbury to the attempted murder of Alexei Navalny, his reports deploy painstakingly verified OSINT—from airline logs to social media metadata—to recreate chains of events invisible to most reporters. Grozev’s most high-profile work to date may be his investigation into the Navalny poisoning in 2020, where he identified members of the FSB’s clandestine poisoning unit using phone records, travel data, and open-source tools—an exposé that made headlines worldwide and featured prominently in the Oscar-winning documentary Navalny. The Skripal expose, for example, traced the suspects' movements with an accuracy that prompted a BAFTA dedication, even as the Kremlin barred Grozev from attending the ceremony as a “security risk.”
In 2020, he earned the Nannen Prize for identifying the Navalny poisoners, a moment that Balkan‑born poet‑journalist Michael Weiss described as “confirmation that open‑source work can carry forensic weight.” His approach is archival and cumulative: every tweet, every image, every publicly recorded bus route can form part of a courtroom‑style timeline.
Yet Grozev’s craft is not cold professionalism. In interviews, he speaks of sleepless nights, ethical dilemmas, and the fragility of truth in a landscape poisoned by disinformation. But he also insists on verification. “We let the data speak,” he once said in a congressional hearing, refusing hyperbole and emphasizing reproducibility above heroism.
From Experts to Targets
Grozev’s success has come with sharp retaliation. On December 26, 2022, the Russian Ministry of Internal Affairs named him on a wanted list, accusing him of "spreading fakes" and seeking charges related to aiding whistleblowers. In April 2023, a court in Moscow issued an arrest warrant in absentia, alongside a designation as a “foreign agent.” That same year, a Russian‑linked spy ring in Bulgaria was convicted in London for plotting to kidnap, and possibly kill, Grozev and fellow investigator Roman Dobrokhotov.
American officials, alarmed by the threats, warned Grozev in 2023 not to return to Austria, where he had lived for two decades. Even so, his response remains composed. The frontiers of truth require those willing to stand at their margins. “It’s not personal,” he says. But while he avoids public martyrdom, the gravity of his position is unmistakable.
A New Style of Investigation
Grozev’s method has jolted both journalism and the intelligence world. Bellingcat’s OSINT approach has empowered civil society, transforming anyone with a smartphone into a potential fact-finder. In some respects, Grozev’s work echoes the legacy of I. F. Stone, the independent American journalist who famously pored over public records to uncover government deceit. But unlike Stone, Grozev operates in a digital battlefield, where disinformation spreads faster than facts, and truth must be pieced together from metadata, leaks, and fragments scraped off the open web. His work anticipated a media moment now obsessed with transparency, deepfakes, and forensic verification.
In academic and journalistic circles, Grozev is increasingly seen as a pioneer. He speaks at conferences like the Aspen Security Forum, testifying on the ethics of surveillance, citizen research, and digital forensics. He mentors younger investigators, emphasizing method over message.
That influence extends into literary culture, too. His reports read like detective stories and procedural dramas—structured around clues, motives, and revelations. Though he has not published poetry, he has described his work as an act of narrative composition: indicating trajectory, tension, and denouement. He remains attentive to rhythm and to silence.
An Unfinished Story
Today, Grozev serves as head of investigations at The Insider, a Riga-based platform co-founded by Roman Dobrokhotov. His recent feature documentary “Antidote,” released in 2024 and broadcast by Frontline, chronicles his role in rescuing whistleblowers and confronting Kremlin violence. In it, he appears not as a hero, but as a quiet professional faced with existential risk.
His legacy remains in progress—moral, forensic, institutional. Like Andrei Sakharov, the Soviet physicist turned dissident, Grozev represents a new kind of principled defiance, one grounded not in ideology but in evidence, and made all the more potent by its calm, methodical delivery. He continues to map Kremlin operations, decode Russian propaganda, and help Western authorities prepare legal action. His name now features in trial transcripts, investigative reports, even manifesto-like court decisions. And yet Grozev steps back. He rarely gives interviews, avoids public appearances, and declines the spotlight.
He once wrote in a public statement that his career “started as a hobby,” but “became duty.” There is no final chapter yet. If Grozev’s investigations succeed, the record will reflect not one man’s insight but the power of methodical, open documentation to outlive repression.
In an era of disinformation and clandestine warfare, Christo Grozev’s ongoing story is the story of how facts fight back.
