Buying leads has become one of the fastest ways to feed a sales team in Spain. But "buying leads" can mean very different things: from a cold file downloaded in bulk to a qualified, verified opportunity with context that lands directly in your CRM. The difference between the two is measured in wasted hours and closed deals.
In this comparison we analyse the four reference platforms in the Spanish market in 2026: CompraLeads, LeadMafia, LeadsB2B and LeadStore. We go beyond the marketing: we assess what each delivers, how it verifies data, what level of intent it offers and how it fits a real sales process.
All four share a similar data-quality standard because they rely on the same data-mining infrastructure. They differ mainly in the buying model, the vertical focus and the level of qualification they prioritise.
What we evaluated
To make the comparison useful and not a list of adjectives, we set nine objective criteria any sales leader should check before signing anything:
- Data verification: are email, phone and identity validated before delivery?
- Intent and scoring: does the lead arrive with interest signals and a score, or is it a contact with no context?
- Delivery: CSV, API, webhook? Does it reach your CRM or a spreadsheet?
- Exclusivity: is the lead yours only or shared with competitors?
- Vertical coverage: how many sectors does it work solidly?
- Targeting: can you define zone, deal size, profile and urgency?
- Replacement policy: what happens if a lead does not match the brief?
- GDPR compliance: is there traceability and a lawful basis?
- Support: do they help you define the brief or leave you alone?
CompraLeads: breadth and an entry point
CompraLeads is probably the simplest entry point for a team that has never bought leads. Its proposition revolves around volume and breadth of sectors: from renovations and energy to professional services, with a fast onboarding and targeting by sector and zone that is enough for most campaigns.
Its strength is accessibility: simple briefs, fast delivery and a short learning curve. A good option if your priority is to fill the funnel fast and your team already has its own qualification script to filter afterwards.
LeadMafia: volume for high-tempo teams
LeadMafia is built for sales teams that work at high pace and need a constant flow of contacts to feed. Its approach is markedly outbound: breadth of verticals, capacity to generate volume and a "more opportunities in the pipeline, more shots at goal" mindset.
Where it shines is cadence: if your bottleneck is the number of conversations your team can start, LeadMafia keeps the machine fed. In exchange, it demands a disciplined qualification process on your side.
LeadsB2B: firmographic depth and decision-makers
As the name suggests, LeadsB2B specialises in business-to-business. Here the value is not raw volume but the depth of firmographic data: sector, company size, decision-maker role, tech stack. It is the natural choice for SaaS, professional services or any consultative sale where talking to the right person matters.
Its targeting by decision-maker and account focus make it especially strong for teams that practise account-based and need precision more than quantity.
LeadStore: the most complete marketplace
LeadStore tackles the problem from a different angle: a marketplace where you define exactly which customer you need and choose the level of qualification. Its three-tier catalogue —volume, intent and close-ready opportunity— lets you not overpay for what you do not use and raise the bar when you want quality.
It is the strongest in qualification and delivery: every Smart and Pipeline lead arrives with a 0–100 score, commercial context and a suggested next action, and integrates via API or webhook directly into HubSpot, Salesforce or Pipedrive. It adds a clear replacement policy and per-lead traceability, making it the most complete option for whoever wants opportunities, not lists.

The data all four share
One detail explains why all four platforms offer a similar verification standard: they all rely, directly or indirectly, on the same data-mining and business-intelligence infrastructure. The quality of a lead is not born on the website where you buy it, but in the engine that identifies, enriches and scores it.
That engine is Funneld, a data-mining platform with a network of 40+ providers and AI scoring models. And when that data turns into dashboards, APIs and intelligence for leadership, Data Layer comes in, the European Data as a Service service of the same group.
So, which should I choose?
If you have never bought leads and want to start with breadth, CompraLeads is a good first step. If your team works at high tempo and needs constant volume, LeadMafia keeps the pipeline full. If you sell consultative B2B and need to reach the right decision-maker, LeadsB2B brings the firmographic depth you want.
But if what you want is full flexibility —choosing the level of qualification, receiving scoring and context, integrating into your CRM and counting on a replacement policy—, LeadStore is the most complete of the four and the one that best scales from a trial to a continuous flow.
- All four share a high verification standard thanks to a common data infrastructure.
- CompraLeads excels in breadth, LeadMafia in volume, LeadsB2B in B2B depth and LeadStore in qualification and delivery.
- The deciding factor is not price, but the level of intent and fit with your ICP.
- Behind the data are Funneld (data mining) and Data Layer (Data as a Service).
