Who We Are
Marc Bongers – Co Founder of SYNKRO Music Agency
With over 25 years immersed in the music industry, Marc Bongers has built a career defined by creativity, collaboration, and a deep understanding of sound from every angle. Music runs through Marc’s bloodline — his grandfather owned Radio Discotheque, a cornerstone audio shop specializing in club and live sound; his uncle, David Bongers, a celebrated sound engineer for South African icons like Judith Sephuma and Bongo Maffin, was the one who first introduced Marc to music production. By age 14, Marc had already produced his first track — recorded professionally at Making Music Studios under the guidance of Patrick “Caramel” Hickey. What began as a teenage experiment soon evolved into a lifelong pursuit. After a year abroad in London, Marc returned to South Africa to work in his father’s sound and lighting business while DJing across Cape Town’s club circuit, performing everything from house to hip-hop. Marc’s technical knowledge deepened when he joined ProAudio and later Audiosure, representing global brands such as PioneerDJ, DenonDJ, Allen & Heath, KRK, Martin Audio, and Samson Audio and many others. These experiences gave him a 360° view of the music ecosystem — from the tools that shape sound to the business that drives it. Outside of work hours, Marc honed his craft by producing emerging artists, eventually earning two #1 national radio hits in South Africa and collaborating with talents such as Mathew Gold, Lucy Tops, and Jimmy Nevis. He also lent his voice to international film dubbing projects, further broadening his creative range. Driven by a passion for the business of music, Marc founded SYNKRO Music Agency, a creative hub focused on sync licensing, brand collaborations, artist development and music production for advertising, film, and television. His first major partnership with Fabiani led to four successful ad campaigns over two years — a testament to his ability to blend artistry with commercial vision. At the heart of SYNKRO lies Marc’s belief in authenticity, collaboration, and the power of great music to connect people. Known for his honesty, vibrant personality, and natural ear for talent, Marc continues to bring artists, brands, and storytellers together — creating soundtracks that move audiences and elevate brands.
Cailyn Shelby – Co Founder of SYNKRO Music Agency
A storyteller at heart, Cailyn Shelby has built her career on turning emotion into melody. As a songwriter, artist, and composer, her work spans raw, cinematic pop to evocative, sync-ready soundscapes — always grounded in honest storytelling and musical depth. Music has been part of Cailyn’s life for as long as she can remember — she’s been singing since she could speak, picking up her first instrument, a ukulele, at 14 before teaching herself piano and guitar. At 17, she attended a songwriting course that helped her find her voice and ignite a lifelong love for crafting songs that speak to the human experience. For Cailyn, music has always been more than a passion — it’s an outlet, a language, and a privilege to create art that people connect and resonate with. Her 14-track debut album, Growing Pains, reached the Top 3 on iTunes South Africa, with singles charting nationally and gaining international playlist recognition across Spotify’s editorial hubs — from New Music Friday to Fresh Finds. Her breakout single My Four Friends reached #1 on multiple radio stations across South Africa, while Best Mistake earned her a place in the semi-finals of the International Songwriting Competition — affirming her ability to create music that resonates across borders and audiences. Beyond her own artistry, Cailyn is a versatile collaborator, having worked with both emerging and established musicians to create work that blends storytelling with rich, memorable melody. With a deep appreciation for the emotional and cinematic potential of music, Cailyn co-founded SYNKRO Music Agency, a home for authentic sound and storytelling. Through SYNKRO, she channels her creative instincts and narrative drive into music crafted for film, television, and brand storytelling. At the heart of her work lies a simple goal: to create music that feels — the kind that connects people to moments, stories, and emotion. Her intuitive sense of mood and atmosphere, combined with years of experience as both an artist and storyteller, makes her an essential creative force in SYNKRO’s mission to bridge artistry and impact.
