Spot hiring trends with Claude Desktop

`get_company_employees` is an MCP tool that pulls historical headcount metrics directly into your workspace. This tool exposes real-world hiring trajectories so you don't rely on outdated self-reported numbers. Your agent compares headcount growth against funding history to flag startups scaling too fast or quietly shrinking. You also use `get_company_details` to verify corporate structures, HQ locations, and founding dates. Combining these tools gives you an unfiltered view of a startup's operational footprint before you ever hop on an intro call.

Track VC portfolios with this Mattermark MCP Server

`get_investor_details` retrieves active portfolio companies and historical check sizes for any venture fund. This tool lets your agent map out who is backing whom without you clicking through dozens of browser tabs. You get the exact fund size, partner details, and co-investment patterns in seconds. When you pair this with `list_investors`, you build targeted syndication lists. Your AI client analyzes past behavior to find lead investors who actually write checks in your specific sector.

Map competitive spaces instantly

`list_similar_companies` identifies direct market competitors based on actual business models. This tool stops you from missing stealth competitors that standard industry codes ignore. Your agent groups these companies to show you exactly where the market is crowded. Using this MCP toolset, you see what competitors are launching and how they position themselves. This gives you a clear edge in market mapping before you start drafting investment memos.
