Is scraping public B2B data legal?

It depends on the jurisdiction, the source's terms and what you collect — and we are not in a position to advise on it. What we can say plainly: business contact data about identifiable people is personal data under the GDPR, so a lawful basis, a retention policy and a route for objections are yours to have in place. Our acceptable use policy applies regardless.

Do you supply leads or a contact database?

No. We sell proxy bandwidth and exit IPs. What you collect through them, and whether you are entitled to, is determined by you and the sources you fetch.

Which plan should an enrichment pipeline use?

ARC Basic for most of it — directory pages, imprints and company sites are small and plain, and it is our lowest price per GB. Move individual platforms to ARC Fast when you see failures on them that a consumer IP would solve.

What happens to bandwidth I do not use this month?

Nothing — it stays on the account. There is no subscription and no expiry, which suits enrichment work precisely because the volume is lumpy: a quiet quarter does not burn a balance a busy one will need.

Proxies for lead generation and B2B data

Building and refreshing a B2B record set means fetching public directories, company sites and listings at a steady rate. One office IP is the bottleneck; a rotating pool turns the same job into a throughput question.

The problem

What goes wrong without the right IPs

The company IP gets limited first

Enrichment runs from one address hit per-IP limits quickly, and the address that gets limited is the one your team also uses for everything else.

Directories are regional

Company registries, trade directories and listing sites rank and filter by the visitor's country. A single collection point gives you one country's view of a market you meant to cover broadly.

Records decay continuously

People change roles and companies move. Enrichment is not a one-off crawl but a refresh cycle, which means the cost of a pass is the cost of the product.

Volume is unpredictable

A big client onboarding is a spike; a quiet month is nearly nothing. A monthly allowance is wrong in both directions, while a balance that does not expire absorbs the spike and waits out the quiet.

Personal data brings obligations

Collecting business contact data in the EU means a lawful basis, a retention policy and a way to honour objections. The proxy does not change any of that — it is your pipeline's responsibility.

Setup

Recommended setup

Directory and company pages are light and rarely need a consumer IP, so the cheapest pool carries most of this.

Plan	Role	Session	Targeting	Price
ARC Basic Rotating ISP	Default for directories and company sites Our lowest price per GB. Company pages, imprints and registry entries are small and plain, which is exactly the shape ARC Basic is cheapest for.	Rotating	Country, optional city	€0.75 / GB €0.59 at 1 TB (−21%)
ARC Fast Rotating residential	For listing platforms that need a consumer IP Residential exits where a directory treats hosting ranges differently, with a sticky handle so a paginated search stays coherent.	Sticky, 10 minutes per search	Country + city	€2.00 / GB €1.12 at 1 TB (−44%)

What refreshing 100,000 company records costs

An illustration with round numbers — your pages, payloads and retry rate will differ. The arithmetic is the real price ladder.

Assumptions

Records: 100,000
Pages per record: 3
Refresh cadence: quarterly
Page weight: 90 KB, assets blocked
Bandwidth per refresh pass: ≈ 27 GB

On ARC Basic

€20.25per refresh pass, excl. VAT

27 GB bought in one purchase at €0.75 / GB (list price).

The same 27 GB on ARC Fast: €51.30 at €1.90 / GB. Route only the jobs that need it through the pricier pool.

Four passes a year bought as one purchase land on a far better rung than four separate ones — and because bandwidth does not expire, buying the year up front costs nothing in flexibility.

Bandwidth never expires, so a bigger single purchase is only ever cheaper per GB. See the ladder.
