What it is.
Brian Balfour is founder and CEO of Reforge, and before that he was VP Growth at HubSpot. Much of the vocabulary growth teams argue in traces back to his essays: growth loops, and the fits between market, product, and channel.
The pace is the point. He describes prioritizing quality over quantity and posting sporadically, which in practice means a handful of pieces a year, each researched to the point of being definitive.
Recent work has moved onto AI: where distribution goes next, and how product teams get restructured when AI does part of the work.
What you get.
- Free long-form essays on AI, product, and growth strategy
- The framework series behind loops, growth models, and the four fits
- Analysis you can still use a year after publication, because the arguments are structural
- The Unsolicited Feedback podcast alongside the writing
- A back catalog that doubles as the Reforge curriculum in public
