Louis-David “LD” Mangin

Co-Founder & CEO

Confiant is not LD’s first rodeo. In fact, it’s the sixth start up he’s been a part of and the second he co-founded. When he’s not keeping the Confiant team collaborating and caffeinated, you can usually count on LD to be planning his next offshore sailing adventure or working on his yoga headstands.

Jerome Dangu

Co-Founder & CTO

Jerome has had a keen interest in computer security ever since he started coding in his childhood. When he’s not building another wild proof of concept, he might be found struggling at the piano or goofing around with his daughter.

We Are Confiant

When LD and Jerome first teamed up in September 2013, cybersecurity technology was up against some bad actors that just couldn’t be beat. They realized it was time to rethink the way the industry tackled malvertising and low quality ads. So they set out to do what had never been done before. In 2017, they launched the industry’s first real-time verification and blocking solution. And today, they’ve assembled an award-winning team of security heroes who are courageously carrying out the Confiant mission: to make the digital world safe for everyone.
