Mostrous studied English at Cambridge University, one of the UK’s most prestigious academic institutions. Here, he developed strong analytical abilities, language skills, and a deep appreciation for context and narrative—qualities that would later define his journalism.

Following his undergraduate degree, Mostrous pursued legal training with a law conversion course, preparing to practise law. He worked briefly as a barrister before deciding to shift his focus to journalism. This legal background proved valuable, equipping him with an understanding of legal systems, evidence, and critical thinking—skills that would greatly support his investigative work in later years.

Early Journalism Career: From Law to Newsrooms

Mostrous began his media career in journalism after his brief period practising as a barrister. His early work included reporting and content production, where he quickly demonstrated an aptitude for digging deep into complex issues. His role at leading newspapers allowed him to learn from experienced editors and develop the craft of professional reporting.

He spent a significant portion of his early career with one of the UK’s major national newspapers, covering politics, economics, and media industry developments. It was during this time that he began to build a reputation not simply as a reporter, but as a journalist who could handle stories requiring depth, sensitivity, and investigative skill.

The Times: Head of Investigations and Major Stories

Alexi Mostrous later joined The Times, one of the UK’s leading newspapers, where he held several important editorial positions, including Special Correspondent, Saturday News Editor, and ultimately Head of Investigations. In this leadership role, he directed investigative reporting and supported major newsroom projects that exposed wrongdoing and influenced public debates.

One of his most notable investigations involved exposing high-profile figures for participating in aggressive tax avoidance schemes. These stories sparked national discussion about fairness, wealth distribution, and public trust in influential figures. For his work, Mostrous received multiple accolades, recognising his ability to break impactful stories.

At The Times, his investigative work expanded beyond tax reporting. He led coverage into challenging topics involving foreign aid, global defence contracts, corporate behaviour, and public policy. This period cemented his reputation as a journalist capable of guiding complex, long-term investigations.

Transition to Tortoise Media: Slow Journalism and Innovation

Alexi Mostrous later joined Tortoise Media as a partner and Investigations Editor. Tortoise is a digital media organisation committed to “slow journalism,” valuing depth, context, and thoughtful storytelling instead of chasing fast news cycles.

A defining feature of Alexi Mostrous’s recent career has been his work in podcasting. By embracing audio journalism, he has helped transform how investigative stories are told and consumed. His podcasts reach millions of listeners globally and combine traditional reporting with narrative depth and emotional engagement.

Sweet Bobby

Sweet Bobby is perhaps Mostrous’s most widely known podcast. The series tells the unbelievable true story of a woman deceived for nearly a decade by someone she believed was her romantic partner. The case involved catfishing—where a person uses a fake identity to deceive others online—and highlighted the psychological and social implications of deception in the digital age.

The podcast received international acclaim, topping charts on major platforms and even being adapted into a documentary series. Its success brought renewed attention to the dangers of online deception and the need for critical thinking in digital relationships.

Hoaxed

Another major audio project is Hoaxed, which investigates one of the most infamous conspiracy theories in recent UK history. In 2014, two children made accusations about a supposed satanic paedophile ring in a wealthy London suburb, a claim that quickly spread online despite being false. Hoaxed explores how this conspiracy theory grew, the people behind it, and the real-world consequences for those falsely accused.

This series highlights the dangers of misinformation and the way narratives can be amplified online without evidence—an issue that resonates strongly in the era of social media and digital conspiracy movements.

Who Trolled Amber?

Who Trolled Amber? examines the online harassment directed at actress Amber Heard during and after the high-profile defamation trial involving Johnny Depp. This podcast looks into how coordinated online trolling campaigns influence public opinion, shape narratives, and impact those involved.
