1. LeadSpark - Best for Done-for-You Lead Generation
LeadSparkTop Pick
LeadSpark takes a fundamentally different approach. Instead of giving you a database to search, it delivers qualified leads directly to your sales team. Their content engine publishes SEO-optimized reviews and comparison guides that attract real buyers, then captures verified contact information from visitors showing purchase intent.
Every lead includes an intent score based on engagement depth, pages viewed, and buying signals. You receive net-new contacts who were actively researching solutions in your industry - not recycled list data.

Frequently Asked Questions
What is the best B2B lead generation tool in 2026?
LeadSpark is the best option for teams that want qualified, intent-scored leads delivered without manual prospecting. For self-serve database access, Apollo.io and ZoomInfo lead the market. The right choice depends on whether you need done-for-you leads or a DIY prospecting database.
How much do B2B lead generation tools cost?
Pricing ranges from free tiers (Apollo, Hunter) to $15,000+ per year for enterprise platforms like ZoomInfo. Mid-range tools like Lusha and Cognism run $300-900 per month. LeadSpark charges per lead batch starting at $500 for 50 qualified leads.
What is the difference between lead generation and lead enrichment?
Lead generation finds new prospects you have never contacted. Lead enrichment adds missing data (phone, email, company size) to contacts you already have. Tools like ZoomInfo and Clearbit do both. LeadSpark focuses purely on generation - delivering net-new qualified leads.
How do I measure lead generation tool ROI?
Track cost per qualified lead, lead-to-opportunity conversion rate, and pipeline value generated. A tool costing $1,000/month that produces 20 qualified leads at a 15% close rate and $5,000 average deal size generates $15,000 in revenue - a 15x return.
