Lead411

Lead411 is a B2B sales intelligence platform that combines a triple-verified contact database of 450M+ contacts and 30M+ companies with native Bombora intent data and unlimited exports, built for high-volume outbound teams that prioritise data accuracy over database size.

Core Features:

Triple-verified contact database with 450M+ contacts and 30M+ companies, refreshed daily, covering verified email addresses and direct dial phone numbers with a strong emphasis on US-based data and real-time validation to reduce bounce rates and improve connect rates.

Native Bombora intent data integration that surfaces companies actively researching topics relevant to your solution, with clear intent scores and intuitive filtering so sales teams can prioritise accounts showing genuine buying signals over cold prospects.

Unlimited contact exports on select plans, allowing high-volume outbound teams to build large prospect lists without per-lead credit limits, with direct export to CRM (Salesforce, HubSpot, Zoho) or as CSV files for offline campaigns.

Advanced search and targeting with firmographic, technographic, and demographic filters including company size, revenue, industry, job title, hiring trends, and technology stack, enabling precise ICP-based list building without manual research.

Chrome extension for LinkedIn prospecting that surfaces verified contact details, company insights, and intent signals directly in the browser, allowing reps to enrich and export leads without leaving their workflow.
