Founded in 2009, Jelli developed a cloud-based platform to modernize the audio advertising industry by enabling programmatic buying and selling of broadcast radio. Its key products, SpotPlan® and RadioDash®, provide tools for media planning, buying, and ad-serving for radio networks, advertisers, and publishers. In November 2018, Jelli was acquired by iHeartMedia, and its technology now powers iHeartMedia's broadcast and digital audio advertising marketplace, making it the largest audio-focused advertising technology platform in the United States.
