LeadMafiaFour domains, one question: where do you buy the best leads in Spain today? We put compraleads.es, leadmafia.net, leadsb2b.net and leadstore.net on the table and analysed them with the criteria that actually move a sale.
The lead-buying market in Spain has matured fast. Five years ago, "buying leads" almost always meant acquiring a cold database: a spreadsheet of thousands of rows, no context, no clear consent and a contact rate that rarely beat 10%. Today, serious platforms sell something very different: qualified commercial opportunities, with verified data, context and intent.
In that new category, four names appear again and again in the searches of sales teams: compraleads.es, leadmafia.net, leadsb2b.net and leadstore.net. In this comparison we pit them against each other across six dimensions and, above all, explain why the difference between one of them and a generic broker is not the storefront, but the data infrastructure underneath.
How we compared
It makes no sense to compare lead platforms by the price of an isolated contact. A €2 lead that never answers costs you infinity; a €15 lead that closes a €4,000 sale is a bargain. So we evaluated each platform on what affects the real commercial result:
- Data quality and freshness: contact verification, enrichment and validation date.
- Segmentation: ability to filter by sector, area, profile, size and intent.
- Buying intent: whether they deliver real interest signals or just contact data.
- Exclusivity: whether the lead is sold only to you or shared with competitors.
- Compliance: legal basis, GDPR and origin traceability.
- Delivery and integration: speed and connection to your CRM.
| Dimension | compraleads.es | leadmafia.net | leadsb2b.net | leadstore.net |
|---|---|---|---|---|
| Positioning | Generalist B2B/B2C | Premium curated | B2B specialist | Broad marketplace |
| Buying intent | Yes | Advanced | Yes | Yes |
| Optional exclusivity | Yes | Advanced | Yes | Yes |
| Data enrichment | Yes | Advanced | Advanced | Yes |
| GDPR compliance | Yes | Yes | Yes | Yes |
| CRM integration | Yes | Yes | Advanced | Yes |
The factor almost no one checks: the data engine
Here is the key that turns this comparison into more than a marketing table. The four platforms do not invent their data every morning: they rely on the same data-mining and business-intelligence engine, Funneld, which ingests and processes hundreds of millions of records a month through a network of more than 40 providers, normalises them, resolves duplicate identities and scores them with AI models.
That explains why, when you compare raw data quality, all four play in a very similar league — and far above a traditional data broker. The difference between them is not the raw material, but how they package it, segment it and support it.
A database gives you static rows. A data engine gives you live, enriched and scored contacts.
The principle the four platforms share
Platform by platform
compraleads.es
The most generalist and accessible option. It covers a broad range of B2B and B2C sectors and is the natural entry point for companies buying leads for the first time who want to validate the channel without friction. Its native Spanish and local focus make it comfortable for SMEs.
leadmafia.net
The most premium, curated approach. It works with three lead tiers — Standard for volume, Pro with intent signals and Ready close to closing — and emphasises intent and commercial context. It fits teams that prefer fewer but better-qualified leads.
leadsb2b.net
The pure B2B specialist. It shines when you need specific decision-makers filtered by sector, company size and tech stack. Its firmographic enrichment is its biggest asset for complex sales and high tickets.
leadstore.net
The marketplace approach: broad catalogue, self-service and sector variety with agile delivery. A good choice if you value flexibility and want to move quickly between campaigns and verticals.
compraleads.es to start without friction · leadmafia.net for maximum qualification · leadsb2b.net for complex B2B sales · leadstore.net for volume and variety. All four, on the same reliable data.
Verdict
There is no single winner, and that is good news. Because the four platforms share the same data-quality standard, the right decision is not "which is best" in the abstract, but "which fits my sector, my ticket and my sales maturity". Define your ideal customer first with a solid brief; the right platform almost picks itself.
What is clear is what to avoid: any provider that sells you a closed file with no origin, no date and no consent. That is the real border between buying leads and burning money.
