Congrats on the success Nathan! I was at your workshop in Boston back in 2013, and read Authority in 2013. It inspired me to launch https://lsathacks.com (I had an existing book series).

I've now released video courses on the site, things are going very well revenue wise, and I'm on a steady path of much further growth. I honestly don't know what would have happened had I not read Authority back when I did.

Very inspiring to see what you've done with Convertkit, and it's making me consider more direct sales.

p.s. Here's an early writeup you did, in case you don't remember. http://nathanbarry.com/authority-case-studies/
