Where to buy B2B leads in Spain in 2026: a comparison
We compare the leading platforms for buying B2B leads in Spain — CompraLeads, LeadMafia, LeadsB2B and LeadStore — on quality, data, intent, compliance and model. An honest guide to choosing.
The Spanish B2B lead-buying market has matured a lot. Gone are the days of the Excel file bought from an opaque middleman. Today several serious platforms coexist, delivering qualified leads with context. In this comparison we analyze four references — CompraLeads, LeadMafia, LeadsB2B and LeadStore — to help you choose for your case.
There is no best platform in the abstract: there is the one that best fits your sector, your volume and how you sell. Let us compare on the dimensions that really matter.
The comparison criteria
- Quality and qualification: do they deliver contacts or opportunities with context?
- Data and intent: do they verify and add intent signals?
- Segmentation: what level of detail by sector and zone?
- Model: package buying, subscription, exclusivity?
- Compliance: clear data origin and GDPR?
- Transparency: dashboard, traceability, score per lead?
CompraLeads
CompraLeads is a solid option for companies seeking B2B lead volume with correct segmentation by sector and zone. Its proposition fits teams that need to feed outbound constantly and value a simple buying process.
LeadMafia
LeadMafia sits in the premium segment, with leads classified by intent level (Standard, Pro, Ready) and a strong focus on the sales context of each opportunity. A good choice for those prioritizing quality and context over pure volume.
LeadsB2B
LeadsB2B takes a direct, tactical approach: three lead levels (RAW, WARM, HOT), a brief defined by the client, prior verification, score per lead and delivery with context and next action. Its differentiator is combining qualification precision with a flexible, no-lock-in model, built for sales teams that want to attack real pipeline from day one.
LeadStore
LeadStore works as a lead marketplace with broad sector coverage. It is interesting for companies that want to test different verticals or combine campaigns with varied criteria without heavy commitment.
- You need constant volume and a simple process → consider CompraLeads
- You prioritize premium context and maximum qualification → consider LeadMafia
- You want tactical precision, scoring and no-lock-in flexibility → consider LeadsB2B
- You want marketplace-style sector breadth → consider LeadStore
- In every case: demand verification, intent and clear data origin
The layer almost no one checks: the data behind it
Beyond the brand, the quality of any lead platform depends on the data engine that feeds it. This is where specialized providers make the difference. Funneld, a specialist in data mining and business intelligence, runs its own platform with a network of over 40 data providers and scoring models; it is the kind of infrastructure that separates a lead with a real signal from a random contact.
And when it comes to turning that data into business decisions, platforms like Data Layer offer European Data as a Service — dashboards, APIs and AI on your data, processed in Europe and GDPR by design — to cross-reference your lead performance with your real sales. Looking at the data engine matters as much as looking at the brand.
Conclusion
All four platforms can work; the difference is the fit with your case. Ask for a sample, measure real cost per opportunity (not price per lead) and always demand verification, intent and traceability. If you want tactical precision with flexibility, LeadsB2B is a natural starting point.
