Prospect Identification The AI scans lead databases and online signals to find companies matching your Ideal Customer Profile (ICP). It evaluates firmographic data (industry, size, revenue), technographic data (software used), and intent signals (hiring activity, funding news). ### 2\. Research and Context Gathering For each prospect, the AI researches the company's website, recent news, LinkedIn profiles, and job postings to find personalization angles. This step produces the context needed to write relevant outreach. ### 3\. Email Generation Using the research data, the AI writes personalized emails for each prospect. Unlike basic mail merge, advanced AI SDRs create unique messages that reference specific company details, recent events, or industry challenges. ### 4\. Multi-Step Sequencing The AI manages automated follow-up sequences across email and sometimes LinkedIn. It tracks opens, clicks, and replies, adjusting timing and messaging based on engagement signals. ### 5\. Meeting Booking When a prospect responds positively, the AI either hands off to a human rep or directly books a meeting using calendar integration. --- ## What AI SDRs Can and Cannot Do | Capability | AI SDR Performance | | --------------------------- | -------------------------------------------- | | **High-volume outreach** | Excellent -- 300-500+ prospects/day | | **Basic personalization** | Good -- references company details | | **Follow-up consistency** | Excellent -- never drops a sequence | | **Meeting booking** | Good -- handles scheduling logistics | | **Discovery conversations** | Poor -- cannot probe or adapt in real time | | **Objection handling** | Limited -- uses scripted responses | | **Relationship building** | Poor -- lacks empathy and judgment | | **Complex negotiations** | Not applicable -- requires human involvement | The best results come from using AI SDRs to fill the top of the funnel while human reps handle mid-funnel and closing activities. --- ## When to Use an AI SDR AI SDRs make the most sense when: * You sell to a large addressable market (1,000+ potential accounts) * Your product has a clear, simple value proposition * Average deal sizes are under $50,000 * Your current SDR team is bottlenecked on outreach volume * You need to test new markets or ICPs quickly They are less effective for: * Enterprise sales with long, complex buying cycles * Highly technical products requiring deep domain expertise in conversations * Markets with fewer than 500 total potential customers --- ## AI SDR vs. Human SDR: Cost and Performance | Metric | Human SDR | AI SDR | | --------------------------------- | --------------- | --------------- | | **Annual cost** | $55,000-$85,000 | $12,000-$36,000 | | **Ramp time** | 3-6 months | 1-2 weeks | | **Daily prospects contacted** | 40-60 | 300-500+ | | **Email personalization quality** | High | Medium-High | | **Follow-up consistency** | Variable | 100% | | **Availability** | Business hours | 24/7 | | **Adaptability to objections** | High | Low | Most teams find the best approach is pairing AI SDRs with human reps: the AI handles volume prospecting and initial outreach, while humans manage engaged prospects and closing. --- ## How SMB Sales Boost Helps AI SDRs need accurate lead data to work effectively.
