Throughout my career as both a product manager and startup founder, there’s been one severely underrated skill I credit for much of my success — and that’s reading. I’m constantly consuming articles on product management, product culture, startups and entrepreneurship to bolster my career as a product person and leader.

“So I thought I’d share some of my favorite reading materials that have helped me through my career in product — and are still crowding my bookmarks tab.”

For this list, I stuck to online posts strictly. (If I listed books, we’d be here forever.) This list is not the be all end all; there are countless ‘must-read’ articles for PMs. I’ve hand-picked articles that specifically helped me during key moments in my career. Some sit outside the product domain, but still directly pushed me as a product manager to connect and empathize with other team members.
