Perplexity

Automated startup and investor discovery

Windsurf agents use `search_startups` and `search_investors` to find targets based on your specific criteria. Cascade scans the market, filters by industry or headcount, and builds a list of candidates without manual input. Once you have a list, the agent uses `enrich_company` to grab firmographics and social signals. You get a clean dataset ready for your next project.

Real-time traction monitoring

Track growth in Windsurf by calling `list_traction_signals` for any company. You'll see social web activity and hiring trends that indicate actual momentum. Chain this with `list_funding_rounds` to verify if the capital matches the hype. Cascade handles the multi-step lookup so you stay focused on the technical implementation.

Deep dive into company intelligence

Access raw growth data through `get_company_stats` to understand a firm's trajectory. If you need recent headlines, `list_company_news` pulls the latest press releases directly into your context window. Use `enrich_person` to verify professional history and background. It's the fastest way to map out key stakeholders for your outreach or research.
