Hey, I'm Kyle, your host on The Compendium podcast. I believe you don't need to commit to a 10-part series to learn about a story. That's why I'm committed to providing easily digestible stories wrapped up in a neat little one-hour-ish package.

Co-Host

Adam Cox

I'm Adam Cox, your side-show freak co-pilot on The Compendium. Think of me as your voice. Whether on your commute, at the gym, or during quiet moments. Join Kyle and me as we dive into mysterious, fascinating, and oddball topics.

Fascinating and intriguing!

Love the wide range of topics that get covered and always in the most digestible, perfect amount of detail! There are so many things that I’ve learnt about which I’d never even heard of! They never fail to make me laugh and listening always makes my day!

Jemaine Clement? Is that you?

These guys know what they’re doing! They’re hilarious and insightful, and tell the greatest most interesting stories from history. Also, who knew Jemaine Clement had a side gig as a podcaster. (Here’s looking at you “Adam”.)
