Most people who visit a company's website leave without ever filling out a form or starting a chat — which means the sales team never finds out a promising prospect was even there. Alphie tries to close that gap: it figures out which companies are browsing a site right now, even if nobody identified themselves, decides whether they look like a good customer based on the company's own criteria, and pings the sales team on Slack so a human can follow up while the visitor is still interested — like a doorbell that only rings when someone worth talking to walks up. Under the hood, Alphie fuses multiple visitor-identification data sources to de-anonymize traffic at the company level, with the vendor claiming up to 75% resolution, then runs each identified company through a configurable Ideal Customer Profile (ICP) scoring model based on firmographics and on-site behavior. Qualified visits trigger real-time Slack alerts with a lead dossier, and an AI-powered chat widget can engage the visitor directly, personalizing page content and handing off to a human rep when needed. Visitors who leave without converting can be enrolled in automated outbound sequences. It integrates natively with HubSpot, Salesforce, Attio, Airtable, and PostHog, plus a REST API for custom CRM connections, and is marketed as GDPR/CCPA-compliant. It's currently in private beta with founders from Y Combinator.
