Benjamin Dyer Diehl, known professionally as Ben Billions, is an American audio engineer, record producer and songwriter from Rehoboth Beach, Delaware. He is best known for his production and engineering work for prominent music industry artists including DJ Khaled, Lil Wayne, BigXthaPlug, Yo Gotti, and the Weeknd. His credits include the latter's hit singles "Might Not," "Often," "Low Life," "6 Inch," and "Acquainted," as well as Maroon 5's "What Lovers Do" and Yo Gotti's "Down in the DM."

Diehl attended Full Sail University to pursue audio engineering and business studies, and graduated with two degrees from the institution. While an audio intern at Miami's Circle House Studios, Diehl built a relationship with frequent studio visitor DJ Khaled and served as lead audio engineer and mixer for his second album, We the Best (2007). Since then, he has worked with Khaled on his subsequent projects while expanding further into production; he meanwhile began working severally with Khaled's collaborators including Rick Ross, Beyoncé, Kodak Black, and Nicki Minaj, among others. Khaled's songwriting often accompanies Diehl's production.
