The agent uses `enrich_company` for basic stats, then calls `list_funding_rounds` to see their capital structure, and finally runs `get_investor_portfolio` on key investors to check deal overlap. ### Sales Target Identification An AE is building a pipeline of ideal customers. They ask the agent to use `search_startups`, filtering for 'FinTech' in 'Austin' with 50-200 employees. The results provide instant, qualified leads. ### Competitor Intelligence A CDO needs a real-time overview of rivals. They ask the agent to list recent news for three competitors using `list_company_news` and then check their current growth metrics with `get_company_stats`. ### Checking an Expert's Background A researcher is meeting a speaker. They give the agent the person’s LinkedIn URL, and the agent uses `enrich_person` to pull up the full academic and career history instantly for prep. ## Benefits - Instead of manually exporting company lists, you simply ask your agent to 'list funding rounds' for a target. The full history appears instantly. - You get immediate insight into market health by calling `search_startups`. Filter millions of companies by criteria like headcount growth or industry sector. - Vetting contacts is easy; just pass a LinkedIn URL and use the `enrich_person` tool to pull their education and career trajectory in seconds. - Due diligence gets faster. You can check recent news via `list_company_news`, track social traction with `list_traction_signals`, and see if they’ve raised money using `list_funding_rounds`. - Understand the competitive landscape by calling `search_investors` to find groups, then use `get_investor_portfolio` to see exactly who they back. ## How It Works The bottom line is you get professional-grade market research and due diligence tools without leaving your chat interface. 1.
