The Trade-Off Test
For every draft value, ask: "What would we NOT do because of this?" If you can't answer, the value is generic filler. "Customer Obsession" only means something if it sometimes means saying no to a feature an investor wants, or delaying a launch because the experience isn't right yet.
Bad: "We value excellence." Better: "We ship small, reversible releases over big-bang launches — even when it means a less impressive-looking roadmap slide."
Pair Every Value With a Behavioural Example
A value without a concrete example is unfalsifiable — nobody can tell if they're living it or violating it. Every value should include a real (or realistic) scenario: who did what, and why it mattered. This is also what makes values usable in performance reviews and hiring debriefs, rather than decorative.
Cap the List at 4–6
Beyond 6–8 values, none of them are memorable and all of them are diluted. Most durable startup culture decks converge on 4–6 sharp, specific values rather than a long list that reads like a generic corporate handbook.
