The MCP returns the size and industry data immediately. ### Need to validate contacts before a campaign? A Marketing Manager inputs a spreadsheet of emails. They instruct their agent to use the combined enrichment capability, which verifies both person and company data points in bulk. ### My AE needs instant info on a client's competitor. The AE is chatting with a prospect and needs context on their main rival. They prompt the agent to use find_company, which immediately provides firmographics for the competitor. ### How do I build a target list of SaaS companies? An Ops team member asks their AI client to run get_prospects, filtering by 'SaaS' and 'California.' The agent returns a curated, actionable list for the next quarter. ## Benefits - Instant Profile Deep Dives: Get detailed professional records, including job titles and social profiles, instantly using the find_person tool. - Holistic Enrichment: Combine company data (find_company) and person details (find_person) into one query for a complete view of any contact. - Targeted Discovery: Use get_prospects to search for new ideal customers based on specific criteria like tech stack or industry. - Risk Management: Calculate an account's current health with find_risk, helping you prioritize outreach efforts accurately. - Efficiency Gains: Automate lead enrichment and segment audience lists without ever having to open the main CRM dashboard. ## How It Works The bottom line is, you use natural language prompts to query massive B2B databases without ever leaving your chat window. 1.
