11x AI

11x AI builds autonomous "digital worker" agents that handle sales development tasks otherwise done by human SDRs. Its flagship product, Alice, manages outbound prospecting end to end: finding leads, researching them, writing personalized outreach across email, LinkedIn, phone, and SMS, following up, and booking meetings, reportedly in over 100 languages. A second product, Julian, is an AI phone agent that handles inbound calls, qualifies leads, schedules meetings, and manages objections using natural conversation. The platform is built for sales teams, revenue operations, and go-to-market leaders at companies that want to scale outbound activity without proportionally growing headcount, and it markets itself as running continuously rather than only during business hours. Under the hood, 11x combines a lead database pulling from more than fifty data sources with an AI personalization engine that writes messages per prospect rather than using fixed templates, plus deliverability and performance analytics. It connects to common sales tools including Salesforce, HubSpot, Gmail, Google Calendar, and Slack, and also exposes an API for custom integrations. 11x AI Inc. is based in San Francisco with an office in London and has raised over $70 million from investors including a16z and Benchmark. Pricing is not published; prospective customers must request a demo, which limits transparent cost comparison for smaller teams.
