Perplexity

Deep-dive company profiling in Claude Desktop

`enrich_company` pulls firmographics, funding rounds, and social signals directly into your local desktop workspace. Your agent reads the raw API payload to build an immediate profile of any startup without you opening a browser. You get instant access to `get_company_stats` to verify headcount growth and team momentum. The data loads directly inside your chat, letting you evaluate prospects against your investment thesis in seconds.

Sourcing targets from your chat panel

`search_startups` scans the market using your specific headcount, location, and industry criteria. Your agent processes these parameters to output a clean list of targets matching your exact investment thesis. You can immediately follow up by calling `get_enrichment_status` on any newly discovered entity. This ensures you only analyze fresh, updated records during your sourcing sessions.

Map investor networks and funding rounds

`get_investor_portfolio` maps out what competitors are backing so you can spot market trends. Your agent cross-references these portfolios with `list_funding_rounds` to trace where the capital is flowing. Combine this with `search_investors` to find active angels or venture firms. You get the raw history without the manual spreadsheet work.
