singer-songwriter
#7 on the UK Singer-Songwriter Charts
Before building brands, David built audiences as a singer-songwriter, performing across the UK and Europe and reaching #7 on the UK Singer-Songwriter Charts. With over 100,000 streams worldwide, his songs connected deeply with fans through honesty, storytelling, and emotion.
Music was more than a career; it was an education in what makes people listen, connect, and care. Standing on stage taught David how to capture attention. Writing songs taught him how to tell stories people remember. Touring taught him how to build a loyal community around his work.
David did a morning workshop with me and my team on LinkedIn and it was unreal. The results we have had in 3 weeks on LinkedIn (organic) has been the best we have ever had in 6+ years of using it. 5 solid leads and 1 converted… mental.
