The AI SDR market exploded in 2024. But which ones actually deliver? We analyzed the top AI SDR platforms based on G2 ratings, market presence, feature completeness, and real customer outcomes.

1. Eve by Cykel

Website: cykel.ai

What it does:
Eve is an autonomous AI sales tool with human-in-the-loop architecture that consolidates your entire GTM stack. Unlike single-function AI SDRs, Eve handles prospecting, research, intent signal detection, LinkedIn automation, and email sequences all in one unified platform.

Key features:

• Integrated GTM platform: Combines enrichment, sequencing, LinkedIn automation, and intent signals in one tool
• Buying signal detection: Analyzes hiring patterns, tech stack changes, and company milestones to identify when prospects are ready to buy
• Smart sequences: Adaptive email and LinkedIn cadences that adjust based on engagement
• Human-in-the-loop controls: Review and approve messages before they send, maintaining brand safety
• Multi-channel orchestration: Coordinates outreach across email and LinkedIn with one workflow

Pricing:
Starting at $300-400/month (replaces 4-5 separate tools that typically cost $650+/month combined)

Best for:
GTM teams tired of managing multiple tools who want strategic intelligence on when to reach out, not just automation of how to reach out.

Unique advantage:
Tool consolidation. Eve replaces your enrichment platform ($200/month), sequencing tool ($150/month), LinkedIn automation ($100/month), and intent data provider ($200/month) with one integrated system. The result: lower costs, faster setup, no integration headaches, and better results because everything works together.

Customer profile:
B2B SaaS companies with 5-50 person teams who value efficiency and want to move fast without managing complex tool stacks.

2. AiSDR

Website: aisdr.com

What it does:
Fully autonomous AI SDR that handles end-to-end outbound from prospect identification through meeting booking without requiring human intervention.

Key features:

• Complete autonomy: AI identifies prospects, writes messages, handles objections, and books meetings
• Multi-channel outreach: Coordinates email, LinkedIn, and phone touchpoints
• Response handling: Automatically processes replies and qualifies leads
• CRM integration: Syncs with Salesforce, HubSpot, and major CRMs
• Deliverability management: Built-in domain warmup and sender reputation monitoring

Pricing:
$1,000-2,000/month depending on volume and features

Best for:
Companies wanting to test outbound with minimal human resources or supplement existing SDR teams without adding headcount.

Trade-offs:
Less control over messaging nuance. Works best when you have very clearly defined ICP and proven messaging already working. Not ideal if you're still experimenting with positioning.

What users say:
Strong for high-volume outreach when you trust the AI to represent your brand. Some users report needing to monitor closely during first 2-3 months to ensure quality remains high.

3. Artisan

Website: artisan.co

What it does:
Agentic sales platform featuring "Ava," an AI SDR that handles outbound prospecting and qualification with enterprise-grade controls.

Key features:

• Agentic AI sales roles: Goes beyond simple automation to strategic decision-making
• Advanced personalization: Uses multiple data sources to craft contextual messages
• Enterprise governance: Approval workflows, audit trails, and compliance controls
• Qualification logic: Scores and routes leads based on engagement and fit
• Performance analytics: Detailed reporting on campaign effectiveness

Pricing:
Not publicly available (opaque pricing model requiring sales conversations)

Best for:
Mid-market to enterprise companies ($50M+ revenue) with complex workflows who need both automation and governance.

Unique advantage:
Strong focus on enterprise requirements including SOC2 compliance, SSO, detailed audit logs, and role-based access controls. Built for companies where compliance and oversight matter as much as automation.

Customer profile:
Regulated industries (fintech, healthcare, legal) and enterprise organizations with strict approval processes.

4. Lusha

Website: lusha.com

What it does:
Data enrichment and prospecting platform with AI-powered engagement features. Started as a contact database, evolved to include outreach automation.

Pricing:

Limitations:
Sequences and automation features aren't as sophisticated as dedicated AI SDR platforms. Better thought of as "enrichment + light automation" rather than full autonomous SDR.

What users say:
Excellent contact accuracy (especially for North American markets). Email deliverability is strong. Automation features are improving but lag behind dedicated AI SDR platforms.

5. Valley

Website: valley.so

AI-powered outbound automation platform focused on LinkedIn and email with strong emphasis on personalization at scale.

Key features:

Unique advantage:

Key Questions Answered

What's the real cost of AI SDR platforms?

Look beyond the platform subscription. Factor in:

• Additional tool costs (if platform isn't all-in-one)
• Domain and email infrastructure ($50-200/month)
• Setup and training time
• Ongoing management overhead

Example: A "cheap" $200/month tool that requires separate enrichment ($200), LinkedIn automation ($100), and intent data ($200) actually costs $700/month plus integration time. Eve at $400/month with everything included is cheaper.

How long until ROI?

Best-in-class implementations show positive ROI within 60-90 days. Expect:

• Week 1-2: Setup and initial campaigns
• Week 3-6: Optimization and message testing
• Week 7-12: Consistent meeting booking and pipeline generation

Can these platforms actually replace SDRs?

Partially. AI SDRs excel at:

• Research and prospect identification
• Initial outreach and follow-up
• Simple qualification questions
• Meeting scheduling

Humans remain essential for:

• Complex objection handling
• Relationship building and trust
• Strategic account planning
• Nuanced qualification

Best model: AI handles top-of-funnel automation, humans focus on high-value conversations.

What about deliverability?

Critical concern. Best practices:

• Use platforms with built-in warmup (Instantly, Reply, Amplemarket)
• Maintain > 85% inbox placement rate
• Keep spam complaints < 0.3%
• Rotate domains and sending accounts
• Monitor sender reputation weekly

Platforms like Eve and AiSDR handle this automatically. With tools like Instantly, you manage it yourself.

How do I decide between autonomous and human-in-the-loop?

Ask yourself:

• How mature is your messaging? (Mature = autonomous works)
• How important is brand voice consistency? (Very important = human-in-the-loop)
• How much oversight capacity do you have? (Low = autonomous)
• What's your risk tolerance? (Low = human-in-the-loop)

Most teams start human-in-the-loop and gradually increase autonomy as they gain confidence.

Key takeaway: The AI SDR market is consolidating toward integrated platforms that combine prospecting, intent signals, and automation in one system. The days of managing 5+ separate tools are ending. Look for platforms that solve multiple problems at once, not just one piece of the puzzle.

Start with a clear understanding of your use case, calculate true total cost of ownership, and run a 30-60 day pilot before committing. The right AI SDR should pay for itself within 90 days through a combination of cost savings and new pipeline generation.
