The podcast advertising vertical is definitely in a growth period. Over the last couple years, more and more players have stepped into the space to try and make it easier for potential advertisers and podcasters to find each other. Of course, this process is nothing new. Services like Blubrry and Podtrac have been doing this since the early days of podcasting. But the recent surge of interest in the medium as an economic engine is drawing a lot of newcomers.

cast.market is a relatively new service that carries the tagline, “We’re creating tools to streamline podcast sponsorship.” cast.market allows both podcasters and those who’d like to advertise on podcasts to sign up for accounts. From there, advertisers can create campaigns. Podcasters can opt-in to the campaigns they like. cast.market then handles the financial transactions to ensure podcast producers get paid:

Our campaign creator makes it easy to get up and running. Craft your message and target your audience. Select a budget and maximum CPM—we’ll take it from there.

And:

We’ll use our analytics engine to offer your sponsorship opportunity to a variety of relevant shows at a competitive price. Podcasters who accept your offer will read your message on the air.

And:

As episodes are recorded, campaign reports provide a high-level overview of your campaign’s success. Listen to delivered messages, view your total impressions, track your budget, and more.

cast.market goes on to bill itself as an “open marketplace” as opposed to “an exclusive network” for sponsorship. The service is already working with an impressive list of shows in all of the usual podcast categories.
