About Us:
At Gumbel Demand Acceleration, we are redefining how musical demand is understood and predicted. By merging music information research (MIR) with data from digital music platforms, we transform sounds into actionable insights, allowing us to predict listener preferences with remarkable accuracy. Our models reveal the connections between how music sounds and who listens to it, helping artists, labels, and A&R teams understand audience demand across diverse segments.
Our tools create data-driven strategies for managing music portfolios and launching new tracks. Betaside Recordings, our sister company, uses these insights to create, acquire, and refine music that resonates globally.
As the music industry evolves with new delivery methods like gaming and experiential platforms, our expertise helps artists and labels adapt, ensuring that great music reaches the right listeners. Gumbel Demand Acceleration empowers artists—especially independent ones—to thrive in a dynamic and competitive market.
