Benjamin Bellamy
Bio
A passionate advocate for Free and Open Source Software, I am Business Development Manager for AI Solutions & Community Management at LINAGORA, where I turn open, privacy-respecting AI into practical products and help grow vibrant contributor communities.
I also founded Ad Aures, creator of Castopod, a free and open-source podcast-hosting platform built to empower creators and strengthen the open podcasting ecosystem.
Active in the Podcast 2.0 community, I contribute to the French radio show Libre à vous !, produced by April (an association whose mission is to promote and defend Free/Libre Open Source Software), and host the podcast RdGP.
Most recently, I joined WikiPortraits, a collective providing freely licensed, high-quality portraits for Wikipedia.
