Custom datasets from any public website

Tell us the sources and the fields you need. We build and run the collection end to end — including the sites that block everyone else — and hand you clean, structured data, as a one-off pull or an ongoing feed.

The problem

The data you need is sitting on public websites, but getting it reliably is its own engineering problem: sources change, defenses tighten, formats drift, and what you collect still has to be cleaned and validated before anyone can use it. Building and maintaining that in-house pulls your team off the work that actually matters.

What you get

Decision-ready data

Not a tool to operate or a raw dump to clean up — structured, ready-to-use data, delivered the way you already work.

  • Any public website or marketplace
  • You define the fields, coverage, and cadence
  • Cleaned, normalized, deduplicated, and validated
  • One-off pulls or continuous monitoring

Use cases

What teams do with it

The same clean, reliable data powers very different decisions.

Market & competitive research

Assemble a dataset across the sites that define your market — products, listings, reviews, specs — without standing up a collection pipeline.

Lead & company data

Build structured lists from public directories and sources, with the exact fields your team needs to act.

Catalog & content enrichment

Fill gaps in your own records — specs, images, descriptions, attributes — pulled from authoritative public sources.

Training & analytics datasets

Source clean, structured, deduplicated data at volume to feed models, dashboards, or analysis.

One-off deep pulls

Need a snapshot, not a subscription? We'll scope a single comprehensive pull and deliver it once.

How it works

From request to data in three steps

  1. 1

    Tell us what you need

    Share the competitors, sites, and data points that matter. We scope coverage, volume, and how you want it delivered.

  2. 2

    We handle everything

    We take care of the entire collection and quality process, end to end. Your team never operates or maintains a thing.

  3. 3

    You get decision-ready data

    Clean, structured data arrives on your schedule — via API, feed, your warehouse, or a dashboard.

How it works

You define it, we deliver it

You set the scope and we handle everything else — every record cleaned, validated, and structured to your spec before it reaches you.

  • Sources you name
  • Fields you define
  • Coverage & cadence you set
  • Cleaned & normalized
  • Deduplicated & validated
  • Quality-scored records
  • Your choice of format
  • One-off or continuous

Why it's reliable

Coverage and accuracy you can trust

Keeping your data complete and correct is our job, not yours — even on the sources that block everyone else.

Complete market coverage

Every competitor, marketplace, and product that matters to you — tracked continuously, so nothing in your market goes unseen.

Local accuracy, worldwide

Prices and availability captured exactly as shoppers see them, in every market and region you sell in.

Even the hardest sources

We reach data behind defenses that block most collectors — so your coverage never has gaps.

Accuracy you can trust

Every record is matched to your catalog, normalized, deduplicated, and quality-scored before it reaches you.

FAQ

Common questions

What sites can you collect from?
Effectively any public website or marketplace — including sources that block most collectors. You name the sources; we handle reaching them and keeping coverage complete.
We've tried collecting this ourselves and kept getting blocked — can you reach it?
That's exactly what we take on. Sources change, access gets cut off, and coverage slips — reaching the hardest sites and keeping them flowing is a relentless, full-time job. We absorb all of it and simply deliver the data, so it never lands back on your team.
Can you collect exactly the fields I need?
Yes. You define the fields, coverage, and cadence, and we build the collection to that spec. If your needs change, we adjust it.
Is this a one-time pull or ongoing?
Either. We do one-off snapshots as well as continuous monitoring that delivers fresh data on a schedule — whatever fits the job.
What shape does the data arrive in?
Clean, structured, deduplicated, and validated — delivered via API, scheduled feed, your data warehouse, or flat-file export. No raw cleanup left for your team.
