Prospecting — B2B Lead Generation from Existing Customers

Overview

Turn existing customers into a search template → find similar businesses on Google Maps → enrich → score → output actionable call lists.

One line: Known customer → profile → Maps search → enrich & rank → CSV call list + JSON index

When to Use

• User gives a customer name + location and asks to find similar businesses
• User asks to build a prospect/call list
• User wants to find new clients in a specific industry (auto body, manufacturing, HVAC, etc.)

Input Required

Even minimal input ("Bob's Auto Body, Orange CA") can start the full flow.

Execution Flow

Step 1: Profile the Existing Customer (8-step fixed process)

Read references/profiling.md for the full 8-step process. Key actions:

1. Google Maps deep dive — Use agent-browser to search [company name] [location], extract: address, phone, rating, review count, business type, hours, website, photos, chain status
2. Review sampling — Sample reviews with keyword filtering (not all reviews). Generic keywords: new, expand, equipment, upgrade, install, moved, bigger + industry-specific keywords (e.g., for auto body: paint booth, insurance, fleet, dealer)
3. Social/web enrichment — Only for 🔴 chain (FB+LinkedIn+website) or 🟡 mid-tier (FB+website). Skip 🟢 small (no website)
4. Output a Profile Card — Standard format saved to prospect-data/{batch}/profile-{name}.json

Tier detection (determines enrichment depth):

• 🔴 Chain/large: name contains chain markers OR >200 reviews
• 🟡 Mid-tier: has website, 50-200 reviews
• 🟢 Small: no website, <50 reviews

Step 2: Maps Batch Search (agent-browser automated)

Read references/search-strategy.md for the complete search framework.

Key principles:

• Multi-center: Large cities (>2M) use 4-6 search centers (e.g., Houston: Downtown, Katy, Sugar Land, The Woodlands, Baytown, Cypress)
• Keyword matrix: 4-6 keywords per center (core + service + equipment + brand + scene)
• Pagination: Scroll and load 3 times per search to get 20-30 results
• Deduplication: Cross-center, cross-keyword deduplication

Search execution:

1. For each center point × each keyword: open Google Maps, extract listings, paginate 3x
2. Collect: name, phone, address, rating, review count, business type, website status, chain markers
3. Dedup: same name + same address = duplicate
4. Remove: permanently closed, non-target industry

Save to: prospect-data/{batch}/candidates-raw.txt (raw extraction log) + candidates.json (deduplicated)

Step 3: Auto-Tier Candidates

Based on Maps data, assign tiers. Chain stores are NOT excluded — they are valid prospects with a different approach strategy.

Chain store prospecting strategy — Read references/chain-strategy.md for the full three-call approach:

• Call 1: Local store — NOT to sell, but to identify procurement decision chain
• Call 2: Regional/corporate — pitch to the person who can approve multi-location deals
• Call 3: Follow-up with proposal

Key principles:

• Chain stores have large, stable equipment needs — one deal can cover multiple locations
• Local store manager is the entry point, not the decision-maker (usually)
• Key question: "Is equipment purchasing handled locally, or should I speak with your regional/corporate procurement team?"

Step 4: Enrich by Tier

Chain enrichment with agent-browser:

1. agent-browser open "[website URL]"
2. agent-browser snapshot -i → extract Services, About, Staff, Contact
3. Check for Portfolio/Cases and News/Blog pages for expansion signals
4. For chains: Look for corporate/region procurement contacts, preferred vendor programs, and expansion news

Chain news search with agent-reach:

mcporter call 'exa.web_search_exa(query: "[company name] expansion OR new location OR equipment", numResults: 5)'

Chain procurement mapping (chains only) — See references/chain-strategy.md for full approach:

• Identify: local manager → regional operations manager → VP of operations / procurement director
• Sources: LinkedIn, corporate website "careers" or "partners" page, news about leadership changes
• Goal: find the person who can approve equipment purchases for multiple locations

Step 5: Score & Rank

Match each candidate against the profile card:

Tie-breaking: buy signal strength → chain (bulk potential) → has phone → closer scale match

Step 6: Generate Custom Sales Openers

Not templates — custom for each prospect based on their data.

Opener must accomplish 3 things: (1) prove you know them, (2) state your purpose, (3) invite dialogue.

Step 7: Output (3-layer structure)

Save to prospect-data/{batch}/:

prospect-data/{area}-{date}/
├── index.json          ← Lightweight index, instant search
├── P001.json           ← Full detail for first prospect
├── P002.json           ← Full detail for next prospect
└── call-list.csv       ← 11-column CSV for calling

See examples/ for sample output files.

Then export CSV from index + P###.json files for calling.

index.json — Search/filter only (few KB):

CSV export — 11 columns, ready to call:

优先级,店名,电话,城市,档位,购买信号,相似客户,业务类型,关键线索,邮箱,开场白

CSV columns map 1:1 to P###.json fields (priority→tier, etc.). CSV is a projection of the JSON, not a separate data source.

Status tracking (in P###.json, not CSV):

待联系 → 已联系 → 意向 / 无意向 / 回访中
                 ↘ 无人接听 → 再试

Step 8: Update contact status

When user reports call results, update P###.json:

"contact_log": [
  {"date": "2026-05-20", "action": "电话", "result": "无人接听", "next": "明后天再试"}
]

And update index.json status field accordingly.

Re-export CSV filtered by status when user needs a new call list.

Critical Rules

1. Every step must execute — skip only if data source has nothing (no website = skip website enrichment)
2. Review sampling, not all — use tiered sampling + keyword filtering per profiling reference
3. Social media by tier only — 🔴 chain gets full search, 🟢 small gets nothing
4. Opener is custom — never use generic templates, always tailor to prospect's specific data
5. Output is 3-layer — index.json for search, P###.json for detail, CSV for calling
6. CSV is a projection — all data lives in JSON; CSV is just 11 columns exported on demand
7. Chain stores ARE valid prospects — do NOT exclude them. Include with a different strategy: local call first → identify procurement decision chain → escalate to regional/corporate buyer. One chain deal can equal many independent deals.
8. Tier labels include chain distinction — use "独立" (independent) or "连锁" (chain) suffix in tier: e.g., "中高端-独立", "连锁-中高端"
9. Chain opener must ask about procurement — "Is equipment purchasing handled locally, or should I speak with your regional/corporate procurement team?"
10. Specialized/certified prospects are high priority — certifications (EV, ISO, specific industry standards) indicate higher equipment requirements and justify premium positioning
11. DATA INTEGRITY — NO FABRICATION — All data in outputs MUST come from actual agent-browser searches, web_fetch calls, or other real data sources. NEVER invent, infer, or hallucinate business details. If a field cannot be verified from real data, mark it as "unknown", "not found", or "pending verification". If a search returns no results or fails due to network issues, report this honestly to the user instead of generating placeholder data.
12. TRANSPARENCY ON DATA GAPS — If Google Maps returns restricted view (limited details), if agent-browser fails to load, or if a business has no visible phone/address/rating, document this in raw_notes and adjust the priority accordingly. Do not fill gaps with assumptions.
13. VERIFICATION REQUIRED — Before marking any prospect as "ready to call", confirm that the phone number was actually extracted from a live page (not a template). If the number is a placeholder or unverified, flag it explicitly: "phone_status": "unverified_placeholder".
