Today I'm pleased to introduce the Kellblog Companion, a new way to explore Kellblog created by Saurav Chowdhury. It reorganizes decades of posts into a structured knowledge base that's easier to browse by topic, easier to search, and easier to use when you're trying
Founders, chief product officers (CPOs), and chief marketing officers (CMOs) spend a lot of time talking with and listening to customers. As they should. And, by and large, they do it well. But there's one common mistake that many smart, strong-willed, and vision-driven leaders make. Surprisingly,
We're in the middle of an AI boom. Capital is abundant, expectations are high, and nearly every company is trying to position itself as a winner in the coming transformation. Amid all the excitement, a basic challenge remains: separating what exists today from what might exist tomorrow. Customers,
I spend a lot of time thinking about go-to-market efficiency — how companies decide where to invest their marketing dollars, how they measure what's working, and how they improve over time. For years, much of marketing measurement has revolved around attribution — trying to determine which programs, campaigns,
We’ve decided, after 122 episodes, to put The Metrics Brothers podcast on hiatus. Let me explain how I think about that decision. On October 20, 1974, the Grateful Dead played what was then billed as their final show before an indefinite hiatus. The band was burned out. The touring

A few years ago I wrote a post called The Decomposition of Marketing. The argument was that startup CEOs were increasingly breaking marketing apart — moving product marketing under product and moving demandgen under sales — in order to get strong leadership in both product marketing and demandgen without having to find
Just a quick post to highlight that Exit Five has published the audio from my presentation at their recent leadership retreat. The presentation was entitled How To Be the CMO Everyone Wants To Work With, and the audio is about an hour long. Exit Five founder Dave Gerhardt published it
There's a question I've been mulling for a while now, and I think it's time to write it down: when is it okay to use generative AI in a given business context, and when does it cross a line? I'll focus on
I recently read The Magic Box Paradigm by Ezra Roizen. It's self-published, was first released in 2016 [1] , and you won't find it on most startup reading lists. The writing is uneven and inconsistent. The metaphors are weird. There are too many TLAs (three-letter
