02What makes it different

Anyone can download the records. Nobody else cleans them up.

The same building is a block-and-lot in one system, a parcel number in another, a document id in a third. The same person is a dozen spellings across a dozen companies. The Rune Engine — our matching machine — collapses all of it into one record per real thing, with one id. Same inputs, same answer, every run.

Then every field keeps a pointer back to the government document that produced it. That is the part you cannot get anywhere else, and it is why an answer here can be checked instead of trusted.

04How it gets here

Free, public, and hard to use, which is the whole opportunity.

None of this is bought. Every record comes from an office that publishes it because it has to. The reason nobody has assembled it is that each source arrives in its own format, on its own schedule, with its own idea of what a building is called.

  1. 01Harvested at the source

    Straight from county recorders, assessors, courts and Secretaries of State. No aggregator in the middle stripping out the source.

  2. 02Nothing overwritten

    Every original value is kept next to its cleaned-up form, so the link behind a number shows what the office actually wrote.

  3. 03Same inputs, same answer

    Ids come straight from the source records, so any answer can be re-run and re-checked. No model, no drift.

  4. 04Updated continuously

    New filings land on the same record, so today’s answer and last quarter’s file point at the same building.

05What buyers ask

Straight answers.

If the records are public, why not pull them myself?

You can. For one building, you should — every answer here links the document so you can check it. The product is the other 22 million: the same building under three numbering systems, the same person under a dozen spellings, combined into one record you can search in seconds.

How fresh is the data?

Per source, and stated rather than averaged: every source has its own publication cadence, and the coverage page lists them. Every figure on this site carries an as-of date. What we never do is imply a freshness the source does not provide.

Why only three states?

Because depth beats breadth in this business. A national footprint of shallow, unsourced rows is what the incumbents already sell. We add a state when we can hold it to the same bar as New York, New Jersey and Florida: clean, checkable, every field backed by its document.

Do you buy data from aggregators?

No. Every record comes from the government office that filed it, free and public. An aggregator in the middle strips out the source, and the source is the product.

Can I get the data outside the terminal?

Yes. CSV export and API delivery, both with the source kept on every field. The data is useful precisely because it leaves with its receipts.
