Lead411
B2B sales intelligence with triple-verified contacts and growth intent data
About Lead411
Lead411 is a B2B sales intelligence and lead generation platform founded in 2001 that helps sales and marketing teams identify and connect with high-value prospects. The platform provides access to over 450 million verified contacts and 30 million companies, specializing in triple-verified email addresses and double-verified direct dials that are automatically re-verified every 90 days to maintain a 96% accuracy rate. What sets Lead411 apart is its proprietary growth intent algorithm that scores companies based on real-time signals like hiring surges, funding events, executive changes, and technology adoption. This allows sales teams to prioritize outreach to companies that are actively in growth mode and more likely to be receptive to new solutions. The platform also integrates third-party intent data via Bombora on premium plans. Lead411 offers seamless integration with over 25 popular CRM and sales tools including Salesforce, HubSpot, Zoho, and Microsoft Dynamics. The platform includes a built-in sales engagement tool called Reach that enables multi-channel campaigns with email, phone, and SMS cadences without switching between tools.
