Leadpipe is a B2B data platform that turns anonymous website traffic into identified contacts and finds people actively researching topics that matter to your business.

Drop a pixel on your website. We identify your anonymous visitors and deliver full contact profiles — name, email, company, job title, phone, LinkedIn — in real time via webhooks or integrations.

• Real-time identification — visitors resolved as they browse
• 60+ data fields per person — business email, direct phone, seniority, company details, demographics
• Webhook delivery — push to your CRM, Slack, or any HTTP endpoint instantly
• Native integrations — Slack, HubSpot, Salesforce, 1000+ apps via Pipedream
• Suppression rules — exclude known customers, competitors, or specific industries
• Credit-based pricing — pay only for unique identifications
