What Customer Discovery does
Customer Discovery is a powerful tool designed for developers and researchers seeking to gather insights into a company's clientele. By leveraging multiple public data sources, this skill enables users to compile a comprehensive list of customers associated with a specified company. The process involves scanning websites, case studies, review sites, social media, job postings, and more, ensuring a thorough investigation into the company's customer relationships.
The skill operates by requiring the user to input the company name, with an optional website URL and a depth tier that dictates how extensively the search is conducted. Users can choose from three depth levels: Quick, Standard, or Deep, each increasing in the number of sources and time required for data collection. The output is a deduplicated report that includes customer names, confidence levels, source types, and evidence URLs, providing a clear view of the findings.
This tool is particularly useful for competitive intelligence, marketing analysis, and business development. It helps users understand who a company sells to, which can inform strategic decisions, partnerships, and market positioning. The confidence scoring system adds an additional layer of reliability to the findings, allowing users to gauge the strength of the evidence supporting each customer claim.
Whether you are a developer looking to integrate customer insights into your applications or a business analyst conducting market research, Customer Discovery offers a structured approach to uncovering valuable information about a company's customer base.
When to use it
Use this tool when you need to gather competitive intelligence about a company's clientele for market analysis or strategic planning.
When not to use it
This skill may not be suitable for real-time customer data or for companies with limited public visibility, as it relies on publicly available information.

|---|---|---|---|
| Company name | Yes | — | The company to research |
| Website URL | No | Auto-detected | The company's website URL |
| Depth | No | standard | quick, standard, or deep |
Procedure
Step 1: Gather Inputs
Ask the user for:
- Company name (required)

- Depth tier — present these options, default to Standard:
- Quick (~2-3 min): Website logos, case studies, G2 reviews, press search
- Standard (~5-8 min): Quick + blog posts, Wayback Machine, LinkedIn, Twitter, Reddit, HN, job postings, YouTube
- Deep (~10-15 min): Standard + SEC filings, podcasts, GitHub, integration directories, BuiltWith, Crunchbase
Step 2: Create Output Directory
mkdir -p customer-discovery-[company-slug]
Step 3: Run Sources for Selected Tier
Collect all results into a running list. For each customer found, record:
- name: Company name
- confidence: high / medium / low
- source_type: e.g., "logo_wall", "case_study", "g2_review", "press", "job_posting"
- evidence_url: URL where the evidence was found
- notes: Brief description of the evidence
Quick Sources
1. Website logo wall
Run the scrape_website_logos.py script:
python3 skills/capabilities/customer-discovery/scripts/scrape_website_logos.py \
--url "[company-url]" --output json
Parse the JSON output and add each result to the customer list.
2. Case studies page
Use WebFetch on the company's case studies page (try /case-studies, /customers, /resources/case-studies). Extract customer names from page headings and content.
3. G2/Capterra reviews
If the review-site-scraper skill is available, use it to find reviewer companies:
python3 skills/capabilities/review-site-scraper/scripts/scrape_reviews.py \
--platform g2 --url "[g2-product-url]" --max-reviews 50 --output json
First, WebSearch for the company's G2 page: site:g2.com "[company]". Extract reviewer company names from review author info.
4. Web search for press
WebSearch these queries and extract customer mentions from results:
"[company]" customer OR "case study" OR partnership"[company]" "we use" OR "switched to" OR "chose"
Standard Sources (in addition to Quick)
5. Company blog posts
WebSearch: site:[company-domain] customer OR "case study" OR partnership OR "customer story"
6. Wayback Machine logos
Run the scrape_wayback_logos.py script:
python3 skills/capabilities/customer-discovery/scripts/scrape_wayback_logos.py \
--url "[company-url]" --output json
Logos marked still_present: false are especially interesting — they indicate former customers.
7. Founder/exec LinkedIn posts
WebSearch: site:linkedin.com "[company]" customer OR "excited to announce" OR "welcome"
8. Twitter/X mentions
WebSearch: site:twitter.com "[company]" "we use" OR "just switched to" OR "loving"
9. Reddit/HN mentions
WebSearch these queries:
site:reddit.com "we use [company]" OR "[company] customer"site:news.ycombinator.com "[company]" customer OR user
10. Job postings
WebSearch: "experience with [company]" site:linkedin.com/jobs OR site:greenhouse.io OR site:lever.co
Companies requiring experience with the product are likely customers.
11. YouTube testimonials
WebSearch: site:youtube.com "[company]" customer OR testimonial OR review
Deep Sources (in addition to Standard)
12. SEC filings
WebSearch: site:sec.gov "[company]" — Look for mentions in 10-K and 10-Q filings.
13. Podcast transcripts
WebSearch: "[company]" podcast customer OR transcript OR interview
14. GitHub usage signals
WebSearch: site:github.com "[company-package-name]" in dependency files, package.json, requirements.txt, etc.
15. Integration directories
WebFetch marketplace pages where the company lists integrations:
- Salesforce AppExchange
- Zapier integrations page
- Slack App Directory
- Any marketplace relevant to the company
16. BuiltWith detection
python3 skills/capabilities/customer-discovery/scripts/search_builtwith.py \
--technology "[company-slug]" --max-results 50 --output json
17. Crunchbase
WebSearch: site:crunchbase.com "[company]" customers OR partners
Step 4: Deduplicate Results
Merge results by company name using fuzzy matching:
- Normalize: lowercase, strip suffixes (Inc, Corp, LLC, Ltd, Co., GmbH)
- Treat "Acme Inc" = "Acme" = "ACME Corp" = "acme.com" as the same company
- When merging, keep the highest confidence level and all evidence URLs
Step 5: Assign Confidence
Apply these rules:
High confidence:
- Logo on current website (from scrape_website_logos.py with confidence "high")
- Published case study or customer story
- Direct quote or testimonial on the company's site
- Official partnership page listing
Medium confidence:
- G2/Capterra review (reviewer's company)
- Press article mentioning customer relationship
- Job posting requiring experience with the product
- YouTube testimonial or video review
- Logo found only in Wayback Machine (was on site, now removed)
Low confidence:
- Single social media mention (tweet, Reddit post)
- Indirect reference ("heard good things about X")
- BuiltWith detection only (technology on site doesn't mean they're a paying customer)
- HN discussion mention
Step 6: Generate Report
Create two output files:
customer-discovery-[company]/report.md:
# Customer Discovery: [Company Name]
**Date:** YYYY-MM-DD
**Depth:** quick | standard | deep
**Total customers found:** N
## High Confidence (N)

## Methodology

public data sources to identify companies that use [Company Name]. Confidence
levels reflect the strength and directness of the evidence found.
customer-discovery-[company]/customers.csv:
CSV with columns: company_name,confidence,source_type,evidence_url,notes
