Stefaans Brümmer, South Africa, is an experienced investigative journalist.

A politics and journalism graduate, Brümmer cut his reporting teeth at The Argus in Cape Town during the tumultuous early 1990s, then joined the weekly Mail & Guardian in Johannesburg as South African democracy dawned in April 1994.

A late-1990s diversion into television and freelancing apart, the Mail was his launchpad for award-winning investigations on the nexus between politics and money, including the Oilgate and Chancellor House party funding exposés.

Brümmer co-founded the non-profit amaBhungane Centre for Investigative Journalism in 2010. Under his joint leadership it grew into an internationally recognized investigative force, responsible with partner publications for the #GuptaLeaks exposé that helped bring down South African president Jacob Zuma in 2018.

Brümmer stepped down as amaBhungane joint managing partner in 2021. He is working on a non-fiction book and is a non-executive director at the IJ Hub, a non-profit that builds investigative journalism in Southern Africa.
