Who this is for

If any of this is on your deskyou have found the right page.

We are not selling a platform you have to learn. We deliver a specific set of data that closes the gap between what your team needs to know and what it actually sees.

E-commerce

“We find out about a competitor's promotion three days after it starts”

We check competitor prices and stock as often as hourly, with an alert the moment someone drops below your floor price — not a report at the end of the week. The signal arrives where your team already sits: Telegram, email, your own spreadsheet.

Retail and brands

“We have no idea what our dealers actually list, or at what price”

Listing-level monitoring across every platform: assortment, availability, new arrivals, search position. An RRP breach becomes a row in a file rather than a rumor from a sales rep. You also see where the category is empty.

Sales

“Our CRM is full of two-year-old contacts”

Company data from open registries and public sources: segmentation, enrichment, database refresh. Your sales team works from a list that is actually alive.

Strategy and finance

“We need a defensible number for a market we are not in yet”

Regular industry snapshots: price movement, assortment depth, who enters and who leaves. One method in every period — which is why the trend can be trusted.

AI and ML

“We need training data our lawyer will sign off on”

Clean, structured datasets from public sources, with documented provenance and jurisdiction for every source. A written legal position is available per project.

How it works

One email from your side.The whole technical side is ours.

Of the six steps, only three are yours, and none takes more than half an hour. Everything else — feasibility assessment, legal review, scrapers, cleaning, monitoring, repairs — happens on our side.

01

You name the sources and fieldsYou

Write to us: which sites, what data, how often, and what you will do with it. Links are enough — no technical specification needed.

Legal review and a fixed quotePROSOX

Our lawyers review the jurisdiction of the sources and of your company. In parallel we work out the technical cost: static pages are cheap, pages rendered with JavaScript are not. You get one figure, not a range.

A sample built on your sourcesPROSOX

Not a demo dataset from someone else's project. We build scrapers for your actual sources and send you a real export in an agreed field structure.

When you need a working tool,not one more file to open.

Small products that live alongside your process instead of adding a new one. Built on the same data feed, as a separate project with a fixed scope.

Integration

An MCP server for your AI agent

Fresh data goes straight into Claude, GPT or your company's own agent. An employee asks a question in plain words and gets an answer based on this morning's data, not on whatever was in the model's training set.

Product

A micro-SaaS for a single task

A price dashboard, an RRP violation monitor, an assortment tracker. Only the screens your team will actually open, with your access rules and your logic. Nothing extra to pay for or configure.

Setup

BI connection and alerts

We connect the data feed to the analytics tools you already use and set up notification rules: a dumping alert in Telegram within minutes, a weekly summary emailed to your manager.

A finished product, not a custom project

Cobi AIa category assistant that keeps watching.

Almost everything we do is built for a specific task. Cobi is the exception: a finished product for teams that sell on marketplaces. It does not replace the category manager. It takes over the part of the job that consists of refreshing browser tabs.

  • 01Price-movement alerts the moment a price changes, not in tomorrow's report
  • 02Two indices for every SKU: your price against direct competitors and against the category
  • 03Day-over-day deltas, competitor groupings, CSV export
  • 04The chat assistant answers a market question and tells you what to do about it
  • 05One dashboard instead of switching between platform seller accounts

Legality and security

Every collection is approvedbefore the first page is read.

Collecting public data is lawful, and on its own that answer is worth little. What matters to your lawyer is something else: who checked, under which jurisdiction, and whether it can be seen in writing. All three are part of the service.

01

Request recorded

We document the sources and the intended use before anything is built.

02

Jurisdiction checked

The legal regime of the source's country and of your company's country. Checked by a cyber-law firm that supports every one of our projects.

03

Compliance checked

Personal data, platform terms, copyright and database rights — in relation to what you intend to do with the result.

04

Collection permitted

The project goes into work, and the written legal position on it is available to you on request — before the contract is signed, not after.

What we do not do at any price

This is the line that separates a vendor your compliance team will approve from one it will turn down.

  • 01We do not log in to accounts, yours or anyone else's, to get at what is behind them
  • 02We do not collect from paid, private or any other closed sections of a site
  • 03We do not bypass access protection or present our scrapers as an authorized user
  • 04We do not take personal data beyond what the applicable jurisdictions permit for your stated purpose
  • 05We do not put load on a source that keeps it from serving its own visitors

If a source can only be collected by crossing one of these lines, we say it cannot be done and suggest an alternative source. That conversation happens before work begins, not after you have paid.

How we start and what it costs

Three ways to startand a fixed figure before you agree to anything.

Cost depends on three things: how many sources, what share of pages need a full browser to render, and how often you need the data. We give you a single number once we have worked through your task: no hourly billing and no extra charges when a source breaks.

Pilot
Check the data first
  • ●One source, one dataset, your real SKUs or segments
  • ●A sample export and a fixed field specification
  • ●A coverage report: what we managed to collect and what we did not
  • ●Legal position on the source included
A fixed amount
We name the price after reviewing your task
Most often chosen
Monitoring
The main way we work
  • ●Collection and delivery on a schedule — from hourly to monthly
  • ●Any combination of file, API, database and cloud
  • ●Every batch validated before it reaches you
  • ●Scraper repairs when sources change — included
  • ●A named contact, with response times fixed in the contract
Monthly — sources × volume × frequency

The questions we hear most often

We answer them here,so you do not have to spend time on them.

Is this legal?+

Collecting data that a website publishes to any visitor without a login is lawful in the jurisdictions where we work. But we do not rely on that general answer: every project is reviewed by a cyber-law firm, covering the legal regime of the source's country, of your company's country, and how you intend to use the result. If the opinion is negative, we say so plainly and propose a different source.

What about personal data and GDPR?+

Most of what we deliver — prices, listings, stock, catalog structure — contains no personal data at all. If a project touches company information or contacts from open registries, the legal review covers the legal basis, retention periods and your obligations as the data controller. We will tell you plainly if a request cannot be fulfilled as it is worded.

How fast can we start, and how often will the data arrive?+

You set the frequency: hourly, daily, weekly, or a one-off snapshot. We first build a sample on your sources and agree the set of fields, then start regular delivery. Sources that render entirely in the browser take longer to build and cost more per page — we tell you which of yours fall into that category before we name a price.

What happens when a source redesigns its site?+

It happens constantly, and it is the main reason most in-house data collection projects quietly die. We monitor for breakage, fix the scrapers within the monthly fee, and warn you separately when a change alters not where a field sits on the page but what it means.

Who owns the data, and will you sign an NDA?+

The result belongs to you: you can use it, store it and sell derived analytics within the limits set out in the project's legal review. We sign NDAs as a legal entity. Your field structures, source lists and SKU mappings are never used for anyone else.

Can we test you before a long contract?+

That is exactly the route we recommend. Take a pilot: one source, your real SKUs, a fixed price. You receive a genuine data export that you can check against the live pages, plus a coverage report — what we managed to collect and what we did not. If the quality does not suit you, that is where it ends.

How much does it cost?+

It depends on the number of sources, how complex the pages are to render, and the frequency. These three things determine everything else — which is why we price against your task rather than publish a price list that would be wrong for your case anyway. The estimate comes as a fixed figure that already includes scraper fixes and legal review.

How do you avoid overloading the sites you collect from?+

The infrastructure is designed to behave predictably: a reasonable request rate, requests spread out over time, and retries after a failure instead of hammering. We do not pose as an authorized user and we do not create load that would stop a site from serving its own visitors. This is a design constraint, not a courtesy.

Insights

Breakdowns and noteson data collection, markets and working with sources.

The practice of collecting public data, the legal side of it, breakdowns of specific platforms, and how category teams work with the numbers.

Practice

Which price to actually collect

A single product listing can show up to six prices: base, strikethrough, discounted, coupon, card, and unit price. We look at which one to use for which decisions, and where mistakes are most common. For category managers and anyone setting up price monitoring.
