What is a B2B lead finder?
A B2B lead finder is a prospecting tool that searches a database of verified business contacts and filters them by criteria like job title, company size, industry, and location. Instantly's B2B lead finder searches 450M+ verified contacts and exports targeted lists directly to outreach campaigns.
What is the difference between a B2B lead finder and a contact database?
A contact database is the underlying data source - verified emails, phone numbers, and firmographic records for millions of businesses. A lead finder is the search interface that queries it using your ICP filters. Instantly combines both: a 450M+ verified contact database with a lead finder that builds and exports targeted lists in minutes.
How does a B2B contact database differ from a CRM?
A B2B contact database holds prospecting data for companies and decision-makers you haven't yet engaged - verified emails, direct dials, and firmographics. A CRM manages relationships with contacts already in your pipeline. Instantly's contact database fills the top of your pipeline with verified leads; those leads then move directly into an Instantly outreach campaign.
Is Instantly a B2B lead generation tool?
Yes. Instantly combines a B2B contact database (450M+ verified contacts) with AI-assisted email outreach and reply handling. It covers both lead finding and outreach in one platform, removing the need to switch between a prospecting database and a sequencing tool.
