Audioboom (originally stylized as "audioBoom") is the hosting site and platform for The First Podcast.
Though far from unknown, Audioboom is one of the "smaller" podcast hosting providers. They offer a flat $10 rate per month. Lars and Joe like its ease of use, attractive layout, sufficient analytics, and effectively unlimited upload count per month (though they suspect the latter may be a relaxation of the rules, as technically the host lists limits, but The First Podcast never seems to run afoul of them).
Audioboom and the show follow each other on social media, and can occasionally be seen liking each other's posts. It is suspected that at least one of their employees listens to the show.
