About the data
The data is compiled from publicly available sources, such as each organization's own sponsor, program or affiliate page, and was verified as of Oct 26, 2026. Prices, terms and deadlines change without notice, so please confirm details with the provider before you buy, apply or promote anything.
The spreadsheets are provided as-is for research and planning. We work to keep them accurate, but we can't guarantee that every detail is current, and we aren't liable for decisions made using the data. Kossin Labs is not affiliated with any newsletter, program or company listed, and inclusion is not endorsement.
Using the files
You can use the spreadsheets in your own work and business. Please don't resell or republish the files themselves as a dataset.
Updates
We plan a monthly re-verification pass, with updates free for buyers.
