Glassbox

Glassbox Media is a New York-based podcast network and talent agency founded in 2021 by David Segura, following his earlier company Giant Media. The company partners exclusively with established podcasters, typically generating between 200,000 and 600,000 monthly downloads or more, who have strong content but need support with monetization and audience growth.

Glassbox provides ad sales, ad operations, content hosting, billing and finance management, and subscription strategy for its roster of creator partners. Its ad sales team maintains relationships with advertisers such as BetterHelp, Butcherbox, Rocket Money, NerdWallet, and Heineken, and manages promotional swaps between podcasts to support audience growth at no direct cost to creators.

The company deliberately narrowed its roster from nearly 100 shows to around 30 core partnerships, concentrating on creators generating the majority of network revenue. Glassbox reports generating nearly 15 million monthly podcast downloads and 10 million video views across its partner shows, which span multiple genres.
