Faster launch vs from scratch
Public Radio Exchange (PRX) operates public radio’s largest podcast distribution marketplace, and they already had a homegrown ad server that enabled podcasters to monetize by inserting audio ads into episodes.
As they scaled, however, their advertisers and podcasters starting asking for more features, and PRX didn't have the engineering resources needed to make these improvements.
So PRX turned to Kevel's ad serving APIs to augment their in-house ad product and quickly add new features and functionality.
Within a few weeks, PRX had upgraded their system - making their podcasters happy while also driving new revenue for themselves.
Before, PRX ads were hardcoded to each episode, so PRX couldn't monetize old podcasts. Now, when a user downloads any episode, PRX pings Kevel with targeting data like the podcast name. Kevel then picks the right audio ads, stitches them into the podcast, and PRX hosts that file on their server.
We've been able to leap ahead using Kevel's APIs for audio podcast advertising. It has all the features to accomplish everything we've needed to do.CTO, PRX
All of the ad decisions are requested server-side — giving PRX the ability to host the compiled audio file on their own servers. This wouldn't be possible with a standard JavaScript ad serving solution.

We've quickly scaled our podcast ad platform using Kevel - allowing us to create a growing line of business.CTO, PRX
Having access to UI and Management APIs makes it easy for PRX to set-up campaigns and manage what promotions are live. This automation ensures that PRX doesn't promote old offers - without having to manually pause them.
If you are looking for API-level ad integration, I haven't found anything that holds a candle to them.CTO, PRX
