Public registries, business directories and catalogs normalized into a consistent, queryable schema.

A source or combination not listed here? We scope custom pipelines against the same legal and technical bar.

Ready datasets

The kind of scale we run

How data reaches you

REST API

Query live or historical data on demand, with an API key and documented endpoints.

Scheduled exports

CSV, JSON or Parquet delivered to S3, GCS or SFTP on your schedule.

Direct warehouse load

Structured tables written directly into your BigQuery, Snowflake or Postgres warehouse.

What we will not do

  • Bypass authentication, CAPTCHAs or any access control
  • Use sources that require authentication, CAPTCHAs or any other bypass of access restrictions
  • Collect personal data, even if technically reachable
  • Guarantee collection from a source that changes its terms to prohibit it

SLA & support

Every recurring pipeline ships with monitored uptime, a defined freshness window, and a support channel — specified in writing before the first delivery.

Data questions, answered

Is web data collection legal?+

We work only with data publicly available without authentication, CAPTCHAs or bypassing access controls. We do not collect personal data. Each source and scope is checked against these boundaries before work begins.

How do you deliver data and how often?+

Via REST API, scheduled export or direct warehouse load. Each source gets an agreed update cadence, from hourly to daily or another business-appropriate schedule.

What happens if a source changes?+

Pipelines are monitored for breakage. If a source changes its structure or restrictions, we assess whether work stays within the agreed boundaries and adjust or retire collection accordingly.

Who owns the collected data?+

You do. Delivered datasets, data schemas and project infrastructure are handed over without vendor lock-in as part of the agreed delivery.

Do you work under NDA?+

Yes. NDA is the default: we can sign your template or provide ours before any technical discussion.
