Step 1: Define Your Ideal Customer Profile (ICP)#
Before building, quantify what makes a good lead:
| Criteria | Weight | High Score (3) | Medium Score (2) | Low Score (1) | |----------|--------|---------------|-------------------|---------------| | Company size | 25% | 500+ employees | 50-500 | < 50 | | Industry | 25% | SaaS, Fintech | Other tech | Non-tech | | Revenue | 20% | > $10M ARR | $1-10M | < $1M | | Tech stack fit | 15% | Uses complementary tools | Partial overlap | No overlap | | Buying signals | 15% | Recent funding, hiring | Growing team | Stable/shrinking |
Total score = weighted sum, normalized to 1-10 scale.
Step 2: Build the Lead Enrichment Agent#
The enrichment agent gathers data about each new lead:
from langchain.tools import tool
@tool
def enrich_company(domain: str) -> dict:
"""Look up company information from the domain name.
Returns company size, industry, funding, and tech stack.
Args:
domain: Company website domain (e.g., 'stripe.com')
"""
# In production, use Clearbit, Apollo, or similar APIs
# This is a simplified example
import requests
response = requests.get(
f"https://api.enrichment-service.com/v1/company",
params={"domain": domain},
headers={"Authorization": f"Bearer {API_KEY}"}
)
data = response.json()
return {
"name": data.get("name"),
"employee_count": data.get("metrics", {}).get("employees"),
"industry": data.get("category", {}).get("industry"),
"estimated_annual_revenue": data.get("metrics", {}).get("estimatedAnnualRevenue"),
"tech_stack": data.get("tech", []),
"recent_funding": data.get("crunchbase", {}).get("lastFundingAmount"),
"description": data.get("description"),
}
@tool
def search_linkedin(company_name: str, role: str) -> list:
"""Find key decision-makers at a company.
Args:
company_name: The company to search
role: Job title to look for (e.g., 'VP of Sales')
"""
# Production: use LinkedIn Sales Navigator API or Apollo
# Returns list of contacts with name, title, email
pass
@tool
def check_intent_signals(domain: str) -> dict:
"""Check for buying intent signals — job postings,
technology changes, funding rounds.
Args:
domain: Company domain to research
"""
# Production: use Bombora, G2, or similar intent data
pass
Step 3: Build the Lead Scoring Agent#
scoring_prompt = """You are a B2B lead scoring specialist.
## Ideal Customer Profile (ICP)
- Company size: 500+ employees (best), 50-500 (good), <50 (poor)
- Industry: SaaS and Fintech (best), Other tech (good), Non-tech (poor)
- Revenue: >$10M (best), $1-10M (good), <$1M (poor)
- Tech stack: Uses [our complementary tools] (best)
- Signals: Recent funding, hiring for relevant roles (positive)
## Scoring Rules
Score 1-10 based on ICP match:
- 8-10: Hot lead — strong ICP match, buying signals present
- 5-7: Warm lead — partial ICP match, worth nurturing
- 1-4: Cold lead — poor ICP match, archive
## Input
You receive enriched company data. Score the lead and explain
your reasoning.
## Output Format
{
"score": <1-10>,
"priority": "hot" | "warm" | "cold",
"reasoning": "<2-3 sentences explaining the score>",
"key_factors": ["<factor 1>", "<factor 2>", "<factor 3>"],
"recommended_action": "<what sales should do next>"
}
"""
Scoring Example#
def score_lead(enriched_data: dict) -> dict:
"""Score a lead based on enrichment data."""
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-4o",
messages=[
{"role": "system", "content": scoring_prompt},
{"role": "user", "content": f"Score this lead:\n"
f"{json.dumps(enriched_data, indent=2)}"}
],
temperature=0,
response_format={"type": "json_object"}
)
return json.loads(response.choices[0].message.content)
Step 4: Automated Personalized Outreach#
Generate personalized emails based on lead data:
outreach_prompt = """You are a professional sales development
representative writing personalized outreach emails.
## Rules
- Reference something specific about the prospect's company
- Connect their pain points to our solution
- Keep emails under 150 words
- Include one clear call-to-action
- Professional but conversational tone
- NO generic phrases like "I hope this email finds you well"
## Our Product
[Your product description and key value propositions]
## Email Structure
1. Personalized opening (reference their company/role)
2. Problem statement (their likely pain point)
3. Solution bridge (how we help)
4. Social proof (brief case study or metric)
5. CTA (specific next step)
"""
def generate_outreach(lead_data: dict, contact: dict) -> str:
"""Generate a personalized outreach email."""
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
model="gpt-4o",
messages=[
{"role": "system", "content": outreach_prompt},
{"role": "user", "content": f"""
Write a first-touch email for:
- Contact: {contact['name']}, {contact['title']}
- Company: {lead_data['name']}
- Industry: {lead_data['industry']}
- Company size: {lead_data['employee_count']} employees
- Recent signals: {lead_data.get('recent_funding', 'None')}
"""}
],
temperature=0.7 # Slightly creative for outreach
)
return response.choices[0].message.content
Outreach Quality Checklist#
| Element | Check | |---------|-------| | Personalization | References something specific about the company | | Relevance | Connects to a real pain point | | Value prop | Clearly explains the benefit | | Social proof | Includes a relevant metric or case study | | CTA | One specific, low-friction next step | | Length | Under 150 words |
Step 5: CRM Integration#
Keep your CRM updated automatically:
@tool
def update_crm(lead_email: str, data: dict) -> str:
"""Update a lead record in the CRM with enrichment
data, score, and activity log.
Args:
lead_email: The lead's email address
data: Dictionary of fields to update
"""
# Example: HubSpot CRM integration
import requests
# Search for existing contact
search_response = requests.post(
"https://api.hubapi.com/crm/v3/objects/contacts/search",
headers={"Authorization": f"Bearer {HUBSPOT_API_KEY}"},
json={
"filterGroups": [{
"filters": [{
"propertyName": "email",
"operator": "EQ",
"value": lead_email
}]
}]
}
)
contacts = search_response.json().get("results", [])
properties = {
"lead_score": str(data.get("score", "")),
"lead_priority": data.get("priority", ""),
"company_size": str(data.get("employee_count", "")),
"industry": data.get("industry", ""),
"last_enriched": datetime.now().isoformat(),
"agent_notes": data.get("reasoning", ""),
}
if contacts:
# Update existing contact
contact_id = contacts[0]["id"]
requests.patch(
f"https://api.hubapi.com/crm/v3/objects/contacts/{contact_id}",
headers={"Authorization": f"Bearer {HUBSPOT_API_KEY}"},
json={"properties": properties}
)
return f"Updated contact {contact_id}"
else:
# Create new contact
properties["email"] = lead_email
requests.post(
"https://api.hubapi.com/crm/v3/objects/contacts",
headers={"Authorization": f"Bearer {HUBSPOT_API_KEY}"},
json={"properties": properties}
)
return f"Created new contact for {lead_email}"
Step 6: Putting It All Together#
The complete workflow as a CrewAI multi-agent system:
from crewai import Agent, Task, Crew, Process
# Agents
enrichment_agent = Agent(
role="Lead Enrichment Specialist",
goal="Gather comprehensive data about leads",
backstory="...",
tools=[enrich_company, search_linkedin, check_intent_signals]
)
scoring_agent = Agent(
role="Lead Scoring Analyst",
goal="Accurately score leads based on ICP match",
backstory="...",
)
outreach_agent = Agent(
role="Sales Development Writer",
goal="Write compelling personalized outreach",
backstory="...",
)
# Tasks (sequential)
enrich_task = Task(
description="Enrich this lead: {lead_email}",
agent=enrichment_agent,
expected_output="Complete company profile"
)
score_task = Task(
description="Score the enriched lead based on our ICP",
agent=scoring_agent,
context=[enrich_task],
expected_output="Lead score with reasoning"
)
outreach_task = Task(
description="If score >= 5, draft a personalized email",
agent=outreach_agent,
context=[enrich_task, score_task],
expected_output="Personalized outreach email draft"
)
# Crew
sales_crew = Crew(
agents=[enrichment_agent, scoring_agent, outreach_agent],
tasks=[enrich_task, score_task, outreach_task],
process=Process.sequential,
verbose=True
)
result = sales_crew.kickoff(
inputs={"lead_email": "jane@enterprise-co.com"}
)
Measuring Sales Agent ROI#
Track these metrics before and after deploying your agent:
| Metric | Before Agent | After Agent | Target Improvement | |--------|-------------|-------------|-------------------| | Lead response time | 4-24 hours | < 15 minutes | 90%+ faster | | Leads researched per day | 10-20 | 100-500 | 10-25x more | | CRM data accuracy | 60-70% | 95%+ | Measured improvement | | Sales rep time on admin | 65% | 20-30% | 50%+ reduction | | Qualified leads to pipeline | Baseline | Track increase | 30-50% increase |
ROI Calculation#
Annual Agent Cost = LLM API costs + enrichment API costs + maintenance
Annual Time Saved = (hours saved per rep) × (hourly cost) × (num reps)
Annual Revenue Impact = (additional qualified leads) × (conversion rate) × (deal size)
ROI = (Time Saved + Revenue Impact - Agent Cost) / Agent Cost × 100%
Most companies see 300-800% ROI within 6 months of deploying sales AI agents.
Common Mistakes to Avoid#
- Scoring without calibration: Train your scoring model on actual won/lost deals
- Generic outreach: If the email could apply to any company, it's not personalized enough
- No human review for outreach: Always have sales review AI-drafted emails initially
- Overloading the CRM: Only write fields your sales team actually uses
- Measuring vanity metrics: Track pipeline impact, not just "leads processed"

Frequently Asked Questions#
Will an AI sales agent replace my sales team?#
No. AI sales agents handle research, data entry, and initial outreach — the repetitive work that keeps reps from selling. The best implementations augment human sellers, making them more productive. Top-performing sales teams use AI agents for 80% of research and admin, freeing reps for relationship building and closing.
How accurate is AI lead scoring?#
With proper calibration against historical win/loss data, AI lead scoring achieves 80-90% accuracy at predicting deal outcomes. That's significantly better than the 50-60% accuracy of gut-feel scoring. The key is calibrating regularly as your ICP evolves.
What data does the sales agent need access to?#
At minimum: company enrichment data (Clearbit, Apollo), your CRM, and email. For advanced agents: intent data (Bombora, G2), LinkedIn Sales Navigator, and your marketing automation platform. Start with enrichment + CRM, then add data sources as you validate ROI.
How do I handle GDPR/privacy with sales AI agents?#
Ensure your enrichment data sources are GDPR-compliant. Only process data with a legitimate business interest. Include opt-out mechanisms in outreach. Log all data processing for audit trails. Consult your legal team before deploying in EU markets.
