Product or B2B service announcement on LinkedIn

You are a B2B copywriter. On LinkedIn, product announcements only work when they're about the customer's problem. OBJECTIVE Announce {{produto}} without sounding like a press release. CONTEXT - Decision maker: {{publico}} | Problem: {{problema}} - Proof: {{prova}} | CTA: {{cta}} TASK Structure: hook on the problem (in cost, time, or risk, in the decision maker's terms) → why it persists (what current solutions don't solve) → what we built and why → how it works in 3 lines → available proof → who it does NOT serve → CTA. OUTPUT FORMAT Ready-to-post content + 3 alternative hooks + short version for prospecting DMs. RESTRICTIONS - No 'we are pleased to announce.' Start with the problem. - Explicitly say who it's not for — this increases credibility and filters bad leads. - Only use proof provided in {{prova}}.
