Andrew “A.J.” Gentile is a writer, producer, voice actor, and entrepreneur best known as the creator and host of The Why Files—a YouTube phenomenon that blends mystery, myth, and science with humor and skepticism. Born on March 5, 1972, in New York City, Gentile grew up in the Bronx and Long Island, developing a lifelong curiosity about unexplained phenomena and the power of storytelling. Before The Why Files, he built a diverse career spanning entertainment and technology, with credits in projects such as The Naughty Show and Stoned Science, voiceover work in video games and animation, and even software development for government agencies. He’s also an accomplished musician, martial artist, and former instructor at the Shaolin American Self Defense Academy, as well as a member of MENSA.

In 2011, Gentile co-founded the cannabis delivery company SpeedWeed with his brother, Gino, and wife, Jennifer, demonstrating his entrepreneurial drive and knack for building innovative ventures. That same creativity later fueled the birth of The Why Files in 2020—a show that investigates conspiracies, ancient mysteries, UFO phenomena, lost civilizations, and hidden histories through a lens of critical inquiry and entertainment. Featuring his wisecracking goldfish co-host, Hecklefish, Gentile’s format combines cinematic storytelling, clear research, and balanced skepticism to make complex or controversial topics both accessible and thought-provoking.

What began as a small experiment quickly evolved into one of the most respected and entertaining mystery channels on YouTube, amassing millions of subscribers and widespread acclaim for its thoughtful approach to fringe subjects. Gentile’s philosophy is rooted in curiosity tempered by discernment—exploring wild ideas without falling into blind belief or cynicism. His thoughtful narration, humor, and ability to present multiple sides of a story have earned The Why Files a loyal following across YouTube, TikTok, and other platforms.

Beyond the screen, Gentile has become a sought-after guest in long-form interviews such as The Joe Rogan Experience and The Shawn Ryan Show, where he shares insights about media integrity, critical thinking, and the human fascination with the unknown. Through The Why Files, A.J. Gentile continues to bridge the gap between science and speculation, inviting audiences to question, laugh, and wonder at the mysteries that shape our reality.
