Hello, we’re Arc Data

You need the data.
You don’t need another tool.

Public data is scattered across websites, PDFs, portals, and APIs. Gathering it once is work. Keeping it accurate is a system.

Arc Data becomes your data team for that system. We combine careful research, purpose-built automation, and ongoing human oversight.

How we work

A service with a
system behind it.

You get the clarity and accountability of a dedicated data partner, powered by infrastructure built for repeatable collection.

(01)

Frame the question

We start with the decision you need to make, then define the sources, fields, history, and refresh rhythm behind it.

(02)

Build the system

We create and validate collectors, reconcile source quirks, and shape the output around how your team works.

(03)

Run & monitor

Schedules run, failures retry, and website changes are handled. We watch the machinery so you do not have to.

(04)

Deliver clean data

Get dependable tables, files, feeds, or API access—with clear provenance and a human who knows the dataset.

Powered by Parseium

Serious infrastructure.
Human service.

Arc Data is built on Parseium, the web data runtime for reliable collection, scheduling, and delivery. Our team uses that foundation to design, operate, and maintain the whole workflow for you.

Prefer to build and run collections yourself? Parseium is also available as a self-serve product for teams and AI agents.

What’s included

Not a handoff.
A data practice.

We own the fiddly parts between “the data exists” and “the data is dependable.”

01

Collection

Websites, portals, PDFs, directories, feeds, and public APIs.

02

Structuring

Schemas, normalization, entity matching, deduplication, and enrichment.

03

Maintenance

Monitoring, retries, source changes, quality checks, and refresh schedules.

04

Delivery

CSV, Excel, database tables, dashboards, or a clean API for your product.
