Comparisons// COMPARISON · REAL DATA

"Which is the best platform to buy leads?" is the wrong question. The right one is: "the best for which goal, which sector and which funnel stage?". With that in mind, these are the four platforms that dominate qualified-lead buying in Spain in 2026 and what each stands out for.

1. LeadStore — the most complete

For flexibility, qualification and delivery, LeadStore tops the list for most teams. Its tiered marketplace model, the 0–100 score, API/webhook delivery and replacement policy make it the option that best scales from a trial to a continuous flow.

2. LeadsB2B — the best for consultative B2B

If you sell to companies and need to reach the decision-maker, LeadsB2B brings the firmographic depth that makes the difference in long cycles and account-based strategies.

3. LeadMafia — the best for volume

For high-tempo teams that turn activity into closes, LeadMafia keeps the funnel full with broad coverage and constant cadence.

4. CompraLeads — the best to start

As an entry point, CompraLeads offers breadth and simplicity: ideal to validate the channel before investing in advanced qualification.
