Linkt Outreach Planner

An AI-powered outreach content generator that receives business signals from Linkt and automatically creates personalized sales and marketing content.

How It Works

Linkt Webhook
  -> POST /api/webhook/linkt
    -> Fetch Signals (Linkt API)
      -> Fetch Entities (Linkt API)
        -> Generate Outreach (GPT-5-mini)
          -> Generate Landing Page (OpenCode Sandbox)
            -> Store in KV
              -> React Frontend + GET /api/landing/:id

1. Linkt detects business signals (funding rounds, leadership changes, product launches, etc.)
2. Webhook sends a run completion payload with signal IDs
3. Agent fetches full signal + entity data from the Linkt API
4. AI generates outreach content and a landing page per signal
5. Frontend lists signals, and the landing page is served via /api/landing/:id
