Stuck on a business problem? Get the thinking tool that solves it.

Describe what you're stuck on. We'll match it to one of Professor Jules Goddard's 21 Maxims, the heretical toolkit he teaches at London Business School.

Why Unstuck exists

Strategy is mostly thinking. Most strategy decks are mostly not thinking.

The 21 Maxims are a pocket toolkit for the moments when a business gets properly stuck. The ones where another workshop won't help, another spreadsheet won't help, and another meeting will actively hurt.

Each maxim is a small, testable heresy. Not best practice, but unique practice. Pick one. Try it on for size. See what breaks, and what suddenly works.

“

Culture eats strategy for breakfast. Truth eats culture for dinner.

How it works

Three steps. No questionnaire. No personality quiz.

  1. 01

    Describe the problem, candidly.

    In plain English. The more honest the description, the sharper the match. We never store anything you type unless you ask us to.

  2. 02

    Get the single most useful maxim.

    One maxim, one clear explanation, one real-world example. Plus two runner-ups, for when the first one feels almost right but not quite.

  3. 03

    Apply it. See what moves.

    Each maxim comes with a concrete 'how to apply' step small enough to try this week. Real change comes from action, not from more analysis.
