The web changes.
Good data should keep up.

We’re building Jsonify so teams can spend less time collecting and repairing data, and more time using it.

Describe once. Rely on it every day.

Businesses need information from thousands of websites and apps. Those sources were built for people to browse, and they change without warning.

Jsonify turns a request into a repeatable extraction pipeline: collect the right fields, check the output, and repair the code when the source changes.

Since 2023, we’ve extracted billions of data points for teams making decisions across markets.
