If your positioning statement could describe a competitor, it isn't positioning.
Positioning is a decision about what you will not be. Most statements fail the substitution test: swap in a competitor's name and nothing breaks.
Anchor on a customer trade-off you are willing to make loudly. Speed over customization. Depth over breadth. Service over price.
Then make the trade-off visible in the product experience, not just the homepage headline.
Positioning that lives only in a deck is a slide. Positioning that shapes pricing, onboarding and support is a moat.
