ART19 announced that its targeted podcast marketplace now includes more than 200 series, from publishers like Headgum, Macmillan, Kast Media, The Paragon Collective, and Techmeme / Ride Home Media. These listener-focused targeted ads will appear across 200 podcasts.

“Our best-in-class deterministic targeting means that ad buyers can craft personalized messages on a listener-by-listener basis,” said ART19’s Chief Revenue Officer Lex Friedman. “We’re bringing the smarts and effectiveness of digital advertising to podcasts.”

Initially focused exclusively on hosting and dynamic ad insertion technology for enterprise publishers, ART19 expanded its focus to include providing direct monetization for its hosting customers earlier this year, with the hiring of Chief Operating Officer Korri Kolesa and Friedman, both formerly of Stitcher/Midroll.

“Headgum is pleased to be a launch partner in ART19’s targeted marketplace,” said Headgum Co-Founder Marty Michael. “Working with a company that loves podcasts and values listener happiness is really important to us, and no one understands how targeted ads can live alongside live reads better than ART19.”

Currently by invitation-only, ART19’s targeted podcast marketplace matches advertisers with podcasts on a listener-by-listener basis, serving millions of impressions each month, using ART19’s Smart Audiences technology. Both brand and direct response advertisers have seen early success since ART19’s marketplace officially launched in April.
