About

Lead Feed Index compares tools that turn public records (FMCSA filings, building permits, NOAA storm data, county records, NIH awards, ClinicalTrials.gov and more) into sales leads. It is run by Siringo Inc., a small software company in New York.

How we make money

• Featured placements (paid by vendors), always labelled "Featured (paid)". Featuring never changes the price-sorted order of comparison tables or what we write.
• Data pack: a downloadable spreadsheet of every listing and its price history for teams doing competitive research.
• We may join vendors' public partner programs later. If we do, the links will be marked and disclosed on every page that has them. Today there are none.

Conflict of interest

Siringo operates FitOut Alerts NYC, a building-permit feed. It is listed under the same rules as every other tool and labelled on every page where it appears.
