Overview

Learn how to build an autonomous AI agent that reactivates dormant leads automatically, saving weeks of manual work and generating revenue from your existing customer database.

Problem Statement

Small businesses typically have hundreds or thousands of dormant leads gathering dust in their CRM. Following up on these leads manually is slow, expensive, and tedious. Yet, these dormant leads represent significant untapped revenue—each successful booking might be worth thousands in lifetime value.

Benefits

An autonomous lead reactivation agent can handle all this work for you. It reaches out to prospects, qualifies them, schedules meetings, and does it all at the speed of an AI. The return on investment is staggering—recoup your development effort in just 3 successful bookings.

Use Case Example

Building a Lead Reactivation Agent with LangGraph

This example shows how to combine LangGraph for workflow orchestration with Vapi.ai for voice calling. The agent analyzes leads in your database, determines which ones are worth calling, and then initiates voice calls. Vapi handles the entire conversation, qualification, and scheduling automatically. Your development effort pays off in days, not months.

typescript
from typing import TypedDict, Optional
import anthropic
from langgraph.graph import StateGraph
from vapi_python import Vapi

# Step 1: Define State for the agent
class AgentState(TypedDict):
    lead_name: str
    lead_email: str
    conversation_history: list
    call_result: Optional[str]

# Step 2: Set up Vapi client for voice calls
vapi = Vapi(api_key="YOUR_VAPI_KEY")

# Step 3: Create LangGraph nodes
def analyze_lead_node(state: AgentState) -> AgentState:
    """Analyze lead eligibility"""
    # Determine if lead is worth contacting
    return state

def call_lead_node(state: AgentState) -> AgentState:
    """Make voice call to lead via Vapi"""
    response = vapi.create_call(
    entity=CallEntity(name=state["lead_name"], number=state["lead_phone"]),
    assistant_id="YOUR_ASSISTANT_ID"
    )
    state["call_result"] = response.status
    return state

# Step 4: Build the graph
graph_builder = StateGraph(AgentState)
graph_builder.add_node("analyze", analyze_lead_node)
graph_builder.add_node("call", call_lead_node)
graph_builder.add_edge("analyze", "call")
graph_builder.set_entry_point("analyze")

reactivation_agent = graph_builder.compile()
