Buyer beware: most "cheap" B2B data tools either: charge per seat ($79+/seat/month), gate features behind tiers, or count "credits" in opaque ways. Real per-result comparison favours pay-as-you-go scraping over database-style SaaS.
Per-result pricing
Kavex: $0.001-0.005/result depending on service. Outscraper: $0.001-0.003. Apify: $0.0002-0.005 (plus compute). Apollo/Lusha/Cognism: priced per seat-month so per-result depends on usage.
For typical 5k-result/month workload
Kavex: ~$10. Outscraper: ~$15. Apollo: $79/seat (fixed). Apollo wins above ~50k results/month per seat; Kavex wins below that.
Honest "cheapest" verdict
For pure scraping volume, Apify is cheapest if you don't value Quality Control. For bundled B2B leadgen workflow with built-in AI personalisation: Kavex. For enterprise contact-DB convenience: Apollo if you can pay per seat.
