Generate code with real startup data in Cursor

`enrich_company` lets your Cursor agent pull live startup data directly into your active files. You write code that interacts with real funding histories and firmographics instead of guessing API shapes or using stale mock objects. This direct connection means your agent can use `get_company_stats` to populate your local database schemas with actual headcount metrics. You build and test your data pipelines using live startup data.

Build automated sourcing tools in your editor

`search_startups` allows your agent to test complex search queries directly inside the Cursor chat. You refine your filtering logic for industries, locations, and headcounts, then let the agent write the corresponding integration code. The agent uses `list_traction_signals` to write automated scripts that flag companies with growing web presence. You get working, tested code that targets high-growth companies.

Map investor networks and funding rounds

`get_investor_portfolio` fetches the exact companies a venture firm backs directly into your workspace. Your agent analyzes these relationships to map out competitor holdings without context switching. You can also run `list_funding_rounds` to inspect capitalization tables and investment dates. This keeps your development environment aligned with real-world venture activity.
