Lead generation tools help you find people to sell to and capture interest from visitors already on your site. B2B databases and email finders supply contact details for decision-makers, enrichment adds company and role data to the leads you have, and lead capture tools turn visitors into contacts through forms and popups. Leads that phone in instead can be traced to their source with call tracking. Visitor identification tools reveal which companies are browsing your site. Compare data accuracy for your target markets, how credits are counted, CRM integrations and how each vendor handles privacy rules such as GDPR.
Lead generation tools operate at different points in the funnel. Some provide B2B contact data, some find and verify email addresses, some identify companies visiting a website, and others enrich records or orchestrate personalized outbound research. Choosing well means deciding whether the missing input is a prospect list, contact details, buying intent, anonymous website traffic, or workflow automation.

Research and enrichment workflows
#3 of 28 in Lead Generation
Clay lets go-to-market teams combine data providers, enrichment steps, research, AI, and outbound preparation in table-based workflows. Choose it when no single database contains every field needed and teams want to chain multiple sources or custom research steps before outreach.
For prospecting plus outreach
#4 of 28 in Lead Generation
Apollo combines a B2B contact database with search filters, enrichment, lists, sequences, and sales-engagement workflows. It is useful when outbound teams want to move from finding prospects to contacting them without exporting every record into a separate sequencing platform; the combined workflow shortens the distance between research and first contact.
Finding business email addresses
#5 of 28 in Lead Generation
Hunter specializes in discovering and verifying professional email addresses associated with companies and domains. Domain Search, Email Finder, verification, and campaign tools make it useful when teams already know which companies or people they want to reach but need reliable business contact details.
For identifying website visitors
#12 of 28 in Lead Generation
Leadfeeder starts from the companies that visit a website, so you do not have to build a cold prospect list from scratch. It identifies organizations behind visits, shows pages viewed and behavior, and helps sales teams prioritize businesses that are already interacting with the site.
Person-level website identification
#13 of 28 in Lead Generation
RB2B helps teams identify certain website visitors and send profile and page-view activity into sales workflows. Its product includes contact-level and company-level identification, enrichment, real-time delivery, and integrations with CRM and automation tools; those signals can be pushed into sales systems while visitor interest is still recent.

Ranked by Market Signal, a score computed from Ahrefs and Semrush data about each vendor's own website. It is not an assessment of the product itself. How this works →
A lead database is used to discover new companies or contacts. Enrichment starts with a record you already have and adds fields such as company details, job information, contact data, or external signals. Many modern platforms provide both.
Yes, RocketReach, Crunchbase, Clay, Apollo.io, Hunter, Lusha, Tidio, Snov.io, Poptin, Leadfeeder, RB2B, Seamless.AI, ConvertFlow, Kaspr and Getsitecontrol all offer a free plan. Free tiers usually come with usage limits, so check whether they cover your volume before relying on them long-term.
