Our Team

María Teresa Ronderos

María Teresa Ronderos

María Teresa is a reporter and editor, and now is focused on finding, alongside her colleagues at CLIP, new paths for a journalism that stands on the shoulders of technology and is able to move things along. She leads the pack trying to make us stay true to our convictions and to go where we really want to go, despite the efforts of reality to sidetrack us. For this purpose, she seeks the advice of wise friends and allies, she finds new media and journalists willing to join our investigations, or who need our help in following promising leads; she finds producers, creatives, developers; experts in hearings, sources, data and witnesses in the streets (when that was still possible). She edits texts and questions anything that doesn’t add up. She looks for patrons who believe that good journalism can transform the world. She believes that journalism is a collective effort that includes those who read us and watch us; they know about what is going on and why it is going on much more than journalists do, and could help us explain it. And this would be no small feat.

Emiliana García

Emiliana García

Emiliana is a journalist-entrepreneur and she believes that in order to do good journalism you need to roll up your sleeves and go find some funding. That’s why she is always on the lookout for philanthropic foundations in sync with CLIP’s mission, or inventing new sources of revenue. But most of all, Emiliana is a budget maniac, and she is convinced that in order to know where we stand, where we want to go and how we can achieve it, we have to plan and we have to budget. And so, her love for investigative journalism and her passion for budgets come together flawlessly in her daily work at CLIP.

Rigoberto Carvajal

Rigoberto is a computer engineer specialized in database technologies and data science. He has had a love relationship with investigative journalism for over ten years now, and he is always looking for ways to empower it through technology.

Andrés Bermúdez Liévano

Andrés Bermúdez Liévano

Andrés is what Colombians call a dog’s leg: always restless here and there and everywhere, talking to people, looking for leads and tying loose ends. He believes in a journalism willing to go beyond city limits and reach the farthest corners, by mule or canoe if that’s the only way, in order to talk to people, understand their problems and also their solutions. He enjoys lending a hand in polishing texts and he believes that journalists need to work as a team, even if we were the last to understand it. Or as we say in Latin America, we are not machos, but we are muchos.

Jairo Peña Casanova

Jairo Peña Casanova is a computer scientist focused on web development in the area of Front-End and UI/UX design. For him, working at CLIP represents a great challenge since he is always in search of obtaining and visualizing data to create news.

Sairo develops products and goes out to look for data to offer a clear and productive visualization to journalists working with CLIP, for whom he has great admiration. According to Sairo, if we don't have technological tools, we wouldn't be able to cross borders and present comprehensive, complete information. In other words, it is important to generate a positive social impact through journalistic research and technological products.

Boris Ramírez

Boris Ramírez

Industrial engineer and quantitative researcher, Boris is obsessed with spatial analysis of criminal activity and the use of data as a means for understanding social network phenomena. Meticulous and fidgety like all engineers, he is trained in the use of technological tools for providing information and georeferenced data.

José Luis Peñarredonda

José Luis Peñarredonda

José Luis wanted to be a journalist since he was five years old, and he became one. One day, he understood that technology was the key to the present, and he worked on blending together his two passions. He worked as a reporter and editor for tech media, and then became interested in how digital culture is shaping the world. Along that path, he learned about how people use the internet to connect and create bonds, and came to CLIP with the objective of making sure the journalism we do reaches more people, gathers greater impact and becomes the basis for a community.

What makes us tick?

CLIP is a non-for-profit organization based in Costa Rica, a Latin American team dedicated to carrying out and coordinating collaborative transnational journalistic investigations as well as putting technological innovation at the service of journalism in the region. We want our investigations —always made in collaboration with media and journalists of Latin America— to untangle abuse of power beyond national borders and make it visible to citizens. In the sea of confusing information we call the internet, our allied and simultaneous publications strive to be seen and to be felt, to interact with people and to bring about change.

We want to connect the dots across borders with the aim of:

Safeguarding public interest

Protecting the environment

Defending human dignity

Widening civil liberties

Exposing misinformation

We want to allow thousands of Latin Americans tired of abuses of power to see more clearly, to strengthen public scrutiny, and to find in CLIP an ally they can identify with and form a powerful community that demands accountability from governments, companies and other powerful actors in the region.

Twelve Tenets of CLIP

Our story

We met during an investigative journalism workshop in 2015 in the Czech Republic, three journalists of different trajectories and from different countries: Giannina Segnini, from Costa Rica, Marina Walker-Guevara from Argentina, and me, María Teresa Ronderos from Colombia. Together, we began to dream about a Latin American center to carry out transnational investigations in collaboration with media and journalists in the region. We agreed that almost all phenomena affecting us, for better or for worse, crossed borders. We also saw that in the region there was a whole generation of investigative journalists skilled in the craft, inspired by ideals of political and social change, and brave of soul. It was a perfect opportunity! And so we raised our glasses to the “Pact of Prague”, bowing that one day we would make it happen. 

 That day was June 3rd, 2019. We started working in CLIP, at least part-time, with Emiliana García, Rigoberto Carvajal, Andrés Bermúdez Liévano, and me. From the get-go, Giannina Segnini has been our mentor and investigative brains, Marina Walker-Guevara has been adviser and support, and Natalia Viana, digital journalism pioneer in Brazil, has filled us with motivation and asked us the hard questions.

The Atlantic Foundation and the Tinker Foundation provided us with seed capital to get started. Local Costa Rican newspaper La Voz de Guanacaste became our fiscal and administrative sponsor, while we worked on legalizing our own institution. On May 2020, we came to legal life.

 That’s how we started. Before completing a year, the team had expanded to include twelve freelancers for different projects; we put up our website with design courtesy of Prodigioso Volcán; our past and present allies add up to 50 news media and organizations in the region, ranging all the way from the United States and Mexico to Argentina and Brazil; and many internationals too, including the European Transnational Investigation Center Occrp, and Bellingcat, a website specialized in open source investigation. 

Alongside them we continued to investigate, developing tools to facilitate research and telling the stories that some would prefer to leave untold. Other generous philanthropists have joined the cause since then.

We do not know where this adventure will take us, but we already feel grateful with everyone who has helped us get this far. We also want you to join the Pact of Prague!
