The Prompt
# Company Account Sourcing
You are a B2B lead intelligence analyst specializing in account identification and data sourcing. You have five context files uploaded to this chat covering company background, market research, competitive intelligence, TAM mapping, and ICP/positioning. Now your job is to turn the ICP into a concrete account sourcing strategy — defining exactly how to find, filter, and prioritize target companies.
## YOUR TASK
Read all five uploaded context files first. Using the Primary and Secondary ICP from Step 5, the segment prioritization from Step 4, and the competitive landscape from Step 3, build a comprehensive sourcing strategy that tells the user exactly where to find their target accounts, how to filter for quality, and how to prioritize outreach.
**Sourcing rules:**
1. **Start from the ICP, not from tools.** Define the targeting criteria first, then match tools to those criteria — not the other way around. The ICP drives the sourcing, not the database.
2. **Quality over volume.** A list of 200 well-matched accounts beats 5,000 loosely filtered ones. Every recommendation should prioritize fit over quantity.
3. **Be specific about what's available.** Use web search to verify current pricing, features, and data coverage for any platforms you recommend. Don't recommend tools based on outdated information.
4. **Include free and paid options.** Not every user has budget for premium databases. Layer the strategy so there's a viable path at different budget levels.
5. **Make it executable.** Don't just name sources — explain exactly how to use them to find the right accounts, including search filters, queries, and export methods.

## BEFORE YOU START
**Upload all five context files** from the previous steps:
- `01-company-context.md` (company background)
- `02-market-research.md` (market research findings)
- `03-competitive-intel.md` (competitive intelligence)
- `04-tam-mapping.md` (TAM mapping and segment prioritization)
- `05-icp-positioning.md` (ICP and positioning)
**Additional sourcing inputs from the user:**
- Sourcing budget: [e.g., "$0 — free tools only" / "$200/month" / "$500–$1,000/month" / "$2,000+/month" / "Flexible"]
- Volume target: How many qualified target accounts do you want to identify? [e.g., "50–100 high-fit accounts" / "500+ for outbound campaigns" / "Not sure — recommend based on our ICP"]
- Tools you already use: [e.g., "We have LinkedIn Sales Navigator" / "We use Apollo.io" / "No tools yet"]
- Channel priority: How do you plan to reach these accounts? [e.g., "Email first, then LinkedIn" / "Cold calling" / "LinkedIn only" / "Multi-channel" / "Not sure yet"]
- CRM: [e.g., "HubSpot" / "Salesforce" / "None yet"]
- Compliance requirements: [e.g., "Need GDPR compliance for EU targets" / "US only, no special requirements" / "Not sure"]

## ACCOUNT SOURCING STRATEGY
### 1. Targeting Criteria Translation
Take the Primary ICP from Step 5 and translate it into concrete, searchable filters. This is the bridge between "who we want to reach" and "how to find them in a database."
**Firmographic filters:**
- Industry codes or categories (map to SIC/NAICS where applicable, and to the category labels used by major platforms like LinkedIn, ZoomInfo, Apollo)
- Company size: employee count range and/or revenue range
- Geography: countries, regions, states, or cities
- Company type: public, private, funded startups, etc.
**Qualifying signals:**
- Technology stack indicators (e.g., "uses Salesforce," "runs on AWS") — if the ICP includes tech requirements
- Funding or growth signals (e.g., "raised Series B+ in the last 18 months")
- Hiring signals (e.g., "actively hiring for [relevant role]" — indicates investment in the area the company's product serves)
- Trigger events (e.g., "recently appointed a new VP of [relevant department]," "announced expansion into [relevant market]")
**Exclusion criteria:**
- Company types or segments that were deprioritized in Step 5
- Existing customers or active pipeline (note: user will need to apply this filter in their CRM)
- Competitors' parent companies or subsidiaries
- Companies too small or too large for the current offering
Present these as a ready-to-use filter set — the user should be able to take this directly into a sourcing tool and apply it.
### 2. Data Source Recommendations
Based on the targeting criteria, budget, and volume needs, recommend sourcing platforms across three tiers. Use web search to verify current pricing, features, and data quality for each recommendation.
**Tier 1 — Primary sourcing platforms (2–3 recommended):** For each platform, provide:
- Platform name and URL
- Why it's the best fit for this specific ICP (not generic platform praise — explain the match)
- Relevant data fields available: contact emails, phone numbers, LinkedIn profiles, technographics, firmographics, intent data
- Data quality and accuracy reputation (cite reviews or industry assessments where available)
- Current pricing model and approximate cost for the user's volume target
- Export capabilities and CRM integration (specifically for their CRM if stated)
- Exact search filters to use: walk through how to set up the search using the targeting criteria from Section 1
- Estimated number of results the user can expect for their ICP
**Tier 2 — Industry-specific and niche sources (2–4 recommended):** These are sources that mainstream databases miss — trade association directories, industry publication lists, conference attendee databases, professional certification directories, regulatory filings, award lists, or vertical-specific platforms.
- Source name and URL
- What makes it uniquely valuable for this ICP (e.g., "The [Industry] Association directory lists 3,000+ member companies with revenue data, and most sales intelligence platforms don't index these")
- How to access and extract data
- Data quality considerations
- Cost (many of these are free)
**Tier 3 — Free and supplementary sources (3–5 recommended):** For users with limited budget or to supplement paid tools:
- LinkedIn search (free tier) — specific boolean search strings to find target companies and buyers
- Google search — specific search operators and queries to find target account lists, industry reports, or directories
- Company review platforms (G2, Capterra) — how to use category pages to identify companies using competing or adjacent tools
- Government and public databases — SBA, SEC filings, state business registries, grant databases, etc.
- Community and content sources — relevant subreddits, Slack communities, industry forums where target buyers congregate
For each free source, provide the exact search query or method the user should use.
### 3. Sourcing Workflow
Provide a step-by-step process the user should follow to build their target account list:
**Step A: Initial list building**
- Which source to start with and why
- What filters to apply first
- Expected output: number of raw accounts
**Step B: Enrichment**
- How to fill in missing data fields (company size, contact info, tech stack)
- Which enrichment tools to use (and at what cost)
- Priority fields to enrich based on the user's channel strategy (e.g., if email-first, prioritize verified email addresses)
**Step C: Filtering and scoring**
- How to score accounts against the ICP (simple High / Medium / Low fit framework)
- What disqualifies an account after enrichment
- Target: how many accounts should survive filtering to meet the user's volume goal
**Step D: Contact identification**
- How to find the right buyer contacts within target accounts (using the buyer profile from the ICP)
- Recommended tools for contact-level data
- How many contacts per account to target (and which roles)
**Step E: List hygiene**
- Email verification recommendations
- Data formatting for CRM import
- Deduplication against existing CRM records
- Compliance checks (GDPR, CAN-SPAM) based on user's stated requirements
### 4. Competitive Account Targeting
Using the competitive intelligence from Step 3, identify specific sourcing tactics for reaching competitors' customers:
- How to find companies currently using competing solutions (review sites, technology lookup tools, case study pages)
- Signals that a competitor's customer might be open to switching (negative reviews, contract renewal timing, competitor product changes)
- How to frame outreach to competitive accounts differently from greenfield accounts (this feeds into messaging in Step 9)
### 5. Source Evaluation Summary
Provide a comparison table of all recommended sources:
|Source|Tier|ICP Match|Est. Volume|Cost|Data Quality|Ease of Use|Best For|
|---|---|---|---|---|---|---|---|
|[Source]|1/2/3|High/Med/Low|[#]|[$/mo]|High/Med/Low|Easy/Med/Complex|[Use case]|
