Overview

11x sells digital workers: Alice, an autonomous AI SDR that sources prospects, researches accounts, and runs multichannel outbound across email and LinkedIn, and Julian, an AI voice agent for phone conversations. Positioned as headcount replacement rather than a rep tool, it targets fast-growing tech companies that want to scale pipeline without hiring SDRs. The platform bundles data, personalization, and sending on premium, sales-quoted annual contracts. It drew scrutiny in 2025 over inflated customer claims, but the autonomous-agent product itself is among the most ambitious in the category.

Best for: The pick when a venture-backed tech company wants to scale outbound pipeline without adding SDR headcount.
