Doctors, investors, engineers, historians and policy specialists publish newsletters on Substack, post on Bluesky and appear on podcasts. Their audiences subscribe by choice, read long posts and come back every week. Those creators rarely show up in tools built around Instagram, TikTok and YouTube.
Subalytics is the data layer for podcasts, Substack and Bluesky: discover who's talking, and see what they say. Partnership teams use it to find expert creators, agencies use it to build shortlists and reports, and platforms use the API to build their own creator databases.
Who uses it
Brands and partnership teams
Search creators by topic and audience size, check how their audience has grown, read their recent posts and shortlist the ones who fit. Useful for newsletter sponsorships, podcast guest outreach and expert partnerships.
Agencies
Build shortlists across clients, compare creators on audience history and engagement, and send reports from the same data. Custom reports are available for recurring work.
Platforms building creator databases
Pull weekly creator snapshots, subscriber history and Substack posts by API, and license the data for your own product. The Substack, Bluesky and Medium APIs share one key and one set of conventions.
Competitive-intelligence teams
See which creators cover your category, how large their audiences are and what they publish, so you know who shapes the conversation before it reaches mainstream media.
Why these channels
Substack, Bluesky and podcasts reward depth. A newsletter post runs to thousands of words, a podcast interview runs for an hour, and readers pay or subscribe because they want that person's view. That makes these channels a good place to find subject-matter experts and the people who follow them closely.
Subalytics focuses on these channels on purpose. Each one is tracked in detail, with audience history, so you can judge a creator by more than a follower count on the day you looked.
