Tide Studio

AI product tactics from people who actually ship

A biweekly newsletter for founders, PMs, and tech leaders building with AI. Written by two operators who build and launch products full-time from Oslo.

Each issue draws from a real product we're shipping 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 we can.

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 don't see traction
