Web Scraping & Data Extraction

The data you need already exists on the web. We retrieve it, structure it, and deliver it ready to use.

Trusted by individuals and teams

The data is out there. But collecting it manually is a nightmare.

This information is public, accessible online. But collecting it manually? Hours of copy-pasting, errors, data already outdated by the time you're done.

And the "no-code" tools on the market? They break as soon as the site is slightly complex or protected.

You need:

A list of qualified prospects in your industry
Your competitors' prices to adjust your strategy
Business contacts in a specific geographic area
Customer reviews on your products or your competitors
Real estate listings, job postings, market data

We extract any public data from the web

Our team develops custom extraction solutions capable of:

What This Means in Practice:

Navigating complex sites (pagination, filters, login)

Intelligently bypassing anti-bot protections

Extracting structured data from any page

Cleaning and formatting data according to your needs

Delivering continuously or as a one-time batch

You're a real estate agency looking for homeowners selling directly. We scan LeBonCoin, SeLoger, and PAP daily, extract private seller listings, retrieve available contact information, and enrich with additional data. Every morning, you have a fresh list of prospects in your CRM.

Our technical approach

Robustness

Our scripts are built to last. When a site changes structure, we adapt quickly. You don't end up with a broken tool.

Handling Protections

Captchas, rate limiting, fingerprinting: we know protection techniques and how to bypass them intelligently when legitimate.

Data Quality

Every extraction includes a cleaning and validation phase. You receive usable data, not noise.

Respecting Limits

We extract at a reasonable rate to avoid overloading source servers. No aggressive behavior that could get your IP blocked.

Proxies and Rotation

For high-volume extractions, we use proxy networks to ensure service continuity.

Is Scraping Legal?

This question comes up often. Here's our position:

Public Data

Extracting publicly accessible data (without login, without violating abusive terms of use) is generally lawful, particularly for competitive intelligence or research purposes.

Favorable Case Law

Several court decisions, notably in the United States (LinkedIn vs hiQ Labs case), have confirmed the legality of scraping public data.

What we don't do:

Our commitment:

We advise you on what's feasible and reasonable. If a request seems legally risky, we tell you and propose alternatives.

contact@lesage.digital

Can you extract data from any website?

From the vast majority, yes. Some highly protected sites (banks, social networks with mandatory login) may have limitations. We tell you what's feasible during the audit.

Will the data be up to date?

For recurring extractions, yes. You define the frequency (real-time, daily, weekly) and we maintain the feed. For one-time batches, data is fresh at the time of extraction.

What happens if the target site changes?

We monitor and adapt. This is included in the subscription for recurring projects. For one-time batches, we guarantee the initial delivery.

Can I extract emails and phone numbers?

Yes, if they're publicly displayed on pages. We don't "guess" emails and we don't use intrusive techniques. For using this data, you remain responsible for GDPR compliance.

How long to receive my data?

A simple extraction is delivered in 2–5 days. A more complex project can take 1–3 weeks for initial setup.
