Apollo

B2B lead database commonly used for cold email list building. Nate and Sav both recommend skipping Apollo broad filters in favour of AI-discovered niche databases like the American Institute of Architects because the niche lists are pre-filtered, cleaner, and produce better reply rates. Apollo is still useful for enriching niche lists with decision-maker emails.

Roberts uses Apollo in ^[src-079] as an example of giving a personal agent a structured external capability through an API-backed skill. His example emphasizes API keys in environment variables and targeted prospecting, such as finding roofers in Austin, rather than broad scraping.
