Actionable tips for shipping products with AI

A biweekly newsletter for operators, written by Katrine and Julie – two full-time product builders based in Oslo.

Each issue draws lessons from a real product we're working on, at one of these stages.

Discovery

We look for problems to solve, ideally in neglected niches with little competition.

Validation

We validate the riskiest assumptions first, as cheaply as possible.

Launch

We ship a small version of the product and measure real usage.

Scale

We scale ideas where we see commercial potential.

We drop ideas that aren't desirable, viable, or feasible

We stop investing in ideas that fail to gain traction
