Alexandre de Santi

About

Managing editor — Brazil

Alexandre de Santi's journalism career began in 1999 as a reporter for radio, web and a daily newspaper, where he honed his skills for five years. In 2011, he embarked on an entrepreneurial path by founding Fronteira, an editorial studio. This venture served as a base to write and edit in-depth and investigative pieces on science, environment, health, and crime — but also music, football, and food — for prominent Brazilian media outlets. During this period, Santi also authored and co-authored three books. In 2018, he took on a new mission as deputy editor at The Intercept Brazil, where he played a key role in significant investigative series, including the Vaza Jato, which had a profound impact on Brazilian politics. At The Intercept, he also led the site's environmental coverage and partnerships with the U.S. newsroom. These efforts led to awards and a successful reader-funded sustainability model for the outlet. Santi joined Mongabay in 2022 as the English editor for Brazil, primarily covering the Amazon, and has served as the managing editor for Brazil since 2025. He also collaborated as an editor for Impedimento, a renowned Latin American football website, and was one of the founding associates of Matinal, a Porto Alegre-based local news nonprofit.
