Invariant

“If you're into investing, Devin goes deep on various industries and looks at what's really going on. He provides very different kinds of insights than you'd get in trad media.”

“Not your typical financial newsletter. Devin's curiosity bleeds through writing style, structure and content-matter of Invariant. I am never quite sure what I will receive in my inbox, but it's always high quality and off the beaten track, and that's why I enjoy it. ”

“Excellent deep dives, deeply researched and accompanied by relevant data. Also great to see someone dig back in to some older industry stalwarts. ”
