Efe Onsoy is a digital marketing strategist, music tech innovator, and software developer with over a decade of experience in the social and music marketing world. Born in Turkey and educated in London, Efe began his journey in 2014, combining his passion for music with his technical skill set to help independent artists thrive in the digital age.
In 2018, Efe co-founded StreamingMafia.com alongside fellow musician Martell Gregson. The idea was born from personal frustration—after years of trying traditional music promotion techniques like playlist pitching and influencer campaigns, they realized those approaches rarely worked for indie artists. Determined to create something more direct and effective, Efe and Martell built StreamingMafia as a Spotify promotion platform powered by proprietary bot software and real user behavior insights. Today, the site has processed over 5 million orders, served 113,000+ users, and partnered with over 650 record labels, making it one of the most impactful Spotify promotion platforms online.
Before StreamingMafia, Efe spent more than three years working as a professional software coder in Panama, gaining hands-on experience in back-end systems, automation, and scalable infrastructure—skills that later helped power the technology behind his music marketing solutions.
Beyond his work with StreamingMafia, Efe is known for his thought leadership in digital strategy, helping creators and brands navigate platforms like Spotify, Instagram, and TikTok. He frequently writes about algorithmic reach, music monetization, and performance-based marketing models for artists.
Whether he's writing code, designing growth strategies, or advising labels on promotion tactics, Efe’s approach is always the same: results over fluff. His mission is to give artists control over their visibility in a world dominated by noise and outdated marketing gimmicks.
