HOSTING, MODERATING, AND INTERVIEWING

A high-stakes stage requires more than a host.

It requires a moderator who can earn trust quickly, ask the right questions, and guide a conversation toward real insight. 

Peabody Award- winning journalist and author Mariana Atencio is trusted by leading global organizations to anchor their most important dialogues and keep audiences fully engaged.

Mariana has interviewed and shared the stage with world leaders, cultural icons, and business executives, including:

  • Pope Francis

  • the King of Spain

  • Heads of State in the US, Brazil, Asia and Venezuela

  • Michael Bloomberg

  • Bill Ackman

  • Arianna Huffington

  • Tyler Perry

  • Rafael Nadal

  • Serena Williams

She is known for making guests feel prepared and at ease, which leads to sharper answers, more candid moments, and takeaways that resonate beyond the event.

Mariana doesn’t just moderate; she acts as an editorial partner. 

With an investigative journalism background, she helps shape the throughline of a program, develops questions that match the moment, and navigates complex topics with clarity, from geopolitics and technology to finance, media, and culture. 

Mariana brings structure without stiffness and energy without chaos, so momentum stays high across multi-session and multi-day programs.

She works seamlessly with global AV and production teams to ensure technical execution is as

polished as the content. 

Mariana is a trusted moderator and MC for major stages and convenings, including:

  • The Future Investment Initiative (FII) in Saudi Arabia

  • Citi Private Bank dialogues

  • Global events for Microsoft

  • Nasdaq

  • Hyundai

  • Foreign Policy, and

  • The United Nations General Assembly

Whether it’s a 60-minute fireside chat with a CEO or a multi-day summit (virtual or in-person), Mariana keeps the conversation on track, the transitions smooth, and your speakers set up to deliver their best.

A Perfect Fit for:

  • Flagship events – where your brand reputation and sponsor ROI depend on flawless execution and memorable content

  • High-profile guests who need to shine on stage – CEOs, newsmakers, investors who need a trusted partner to make them look sharp

  • C-suite in the hot seat – earnings calls, town halls, shareholder meetings where one wrong question derails the narrative

  • Panels where controversial or polarizing topics might come up – where you need a moderator who can navigate tension

  • Geopolitically conversations – where you need credibility, nuance and high-energy

  • Technical or complex subject matter for non-technical audiences – translating AI policy, financial regulation, climate science into insights executives can actually use

  • Global or multi-day summits – where consistency, momentum, and seamless transitions across sessions make or break the experience

  • Events blending business and culture – where you need someone fluent in both boardroom strategy and broader global context

  • Sponsor-heavy programs requiring editorial independence – where the moderator must balance commercial interests with journalistic integrity so content doesn't feel like an infomercial

  • Celebrity or athlete interviews for corporate audiences – where star power needs a moderator who's interviewed global icons and knows how to navigate the sensitivities of the interviewee 

  • Events where the "wrong" moderator is a liability – emcees who can't read the room, comedians who undercut gravitas, corporate trainers who can't handle spontaneity


Experience Mariana's energy and gravitas kicking off the eMerge Americas 10th anniversary tech conference in Miami. 

Mariana moderates a high-level conversation on the future of mobility with Hassan Jameel (Vice Chairman, Abdul Latif Jameel), Mate Rimac (Founder, Rimac Group), and Marko Pejković (CEO, Verne) — leaders behind some of the most disruptive companies in the automotive world. 

Mariana sits down with Shark Tank's Daymond John for a candid conversation, summing up tangible lessons for the audience
