This guide provides a definitive evaluation of the leading AI SDR agents currently transforming outbound sales. You will learn: 1. The fundamental shift from linear automation to agentic autonomy. 2. A detailed analysis of the top 5 agents (11x.ai, Artisan, Regie.ai, AiSDR, and Luna). 3. Key comparison metrics for integration, lead quality, and cost-efficiency. 4. Strategic frameworks for implementing AI agents in a high-growth sales environment.
AI SDR agents are autonomous software entities that leverage Large Language Models (LLMs) to handle the complete outbound sales lifecycle—including lead research, data enrichment, personalized drafting, and multi-channel delivery—without manual intervention. Unlike traditional sequencing tools, these agents operate on goals rather than triggers, making them the cornerstone of the modern Agentic Automation stack in sales.
The traditional Sales Development Representative (SDR) model is undergoing a seismic shift. As we enter the era of Agentic Automation, the focus has moved from scaling human effort to deploying autonomous software that thinks, researches, and executes. The following analysis explores the top five AI SDR agents currently dominating the market.
What is an AI SDR Agent?
An AI SDR Agent is an autonomous system capable of performing end-to-end sales tasks by reasoning through lead data and context. Unlike basic automation, which follows if-then rules, agentic systems use LLMs to adapt their strategy based on prospect responses and intent signals.
1. 11x.ai (Alice)
Alice by 11x.ai is widely considered the gold standard for fully autonomous SDR work. Alice doesn’t just send emails; she researches prospects across multiple sources, monitors for job changes, and crafts messages that feel indistinguishable from human output. Her primary strength lies in her ability to operate with minimal supervision once the initial persona parameters are set.
2. Artisan (Ava)
Ava is the cornerstone of the Artisan platform. She functions as a unified sales agent, integrating prospecting, enrichment, and outreach into a single workflow. Ava’s standout feature is her deep integration capabilities, allowing her to reside within your existing CRM and tech stack while autonomously updating records and managing follow-ups.
3. Regie.ai
While some agents focus on total replacement, Regie.ai excels in the hybrid model. It leverages agentic workflows to help human SDRs scale their personalization. Regie’s agents can automatically generate entire campaign sequences based on specific personas and intent data, ensuring that every touchpoint is relevant and data-driven.
4. AiSDR
AiSDR is built for speed and ROI. It specializes in converting inbound leads and cold outbound via hyper-personalized email conversations. Its unique selling proposition is its ability to handle complex objection handling autonomously, steering prospects toward booking a meeting on your calendar without human input.
5. Luna.ai
Luna.ai focuses on solving the ‘deliverability and relevance’ crisis. Using advanced agentic logic, Luna scans the internet for real-time triggers—such as news articles, social posts, or financial reports—to provide a context-rich outreach that dramatically increases response rates compared to traditional templates.

The Shift to Agentic Sales Workflows
Deploying an AI SDR is not about replacing your team; it is about elevating them. By offloading the ‘grunt work’ of prospecting and initial outreach to agents, human reps can focus on high-value activities: closing deals and building relationships. The success of agentic automation depends on high-quality data and clear persona definitions.
