Podcasts
Subalytics tracks 250K+ podcasts. It's a curated list of news, business, sports and technology shows, the conversations where executives, investors and specialists talk. It isn't every podcast published, and more shows can be added on request.
Transcripts cover episodes published since each podcast was first tracked. Back catalogues before tracking began are available as historical data on request.
Substack
167K+ newsletters with weekly snapshots of subscriber counts (free and paid where the publication shows them), publication details and category. Posts include reactions, comments, word count and audience (free or paid).
Bluesky
300K+ accounts with weekly follower snapshots. Posts that mention a monitored company are available with full text within minutes of posting.
Medium
85K+ publications with profile and follower data. Medium posts aren't part of the API.
Public companies
20,000+ monitored public companies, each with ticker, SEC CIK, exchange, sector and industry. The full list is available from the entity-companies endpoint.
