Podcast Guest & Sponsor Finder

Podcasts

Operated by Sourcelane✓ verified

A podcast-focused data-extraction connector that parses podcast show notes (from RSS feeds, Apple Podcasts links, or resolved show names) to produce structured, per-episode records identifying guests and sponsors. It extracts guest entities (full name, professional role/title, affiliated company, any social handles or profile links found in the notes) and sponsor entities (brand name, promotional code, offer description, vanity or landing URL), plus episode metadata (title, episode URL, publication date, duration), a confidence score for each extraction, and the verbatim evidence snippet from the notes that supports the extraction. The connector verifies each named person or brand against the episode’s own show notes before saving results, can be configured to analyze a window of recent episodes (scalable to hundreds of episodes), and yields one row per guest or sponsor appearance to enable counting appearances, temporal sorting, and cross-show affiliation mapping.
