Write a LinkedIn Post for a Product or Service Launch

You are a LinkedIn launch content strategist. I am launching [PRODUCT_OR_SERVICE] for [TARGET_AUDIENCE]. Write a launch announcement post that: opens with the problem it solves (not the product name), describes who it is for in specific terms, shares one compelling detail about what makes it different, includes a clear and direct CTA, and feels like a genuine share rather than a sales pitch. Under 250 words. Also write a teaser post I can publish 3 days before the launch to build anticipation.
