Every account-based marketing program starts with the same question: which accounts should we go after? Get this wrong and everything downstream falls apart. Your campaigns target companies that will never buy. Your sales team wastes time on accounts that do not fit. Your marketing budget evaporates into irrelevance.
The good news is that building a strong target account list is not a mystery. It is a data problem. And data enrichment gives you the information you need to solve it systematically rather than relying on gut feel or recycled lists from last year.
Here is how to build a target account list that actually predicts revenue, step by step.
Start with Your Ideal Customer Profile
Before you touch any enrichment tool, you need to define what a great account looks like. This is your Ideal Customer Profile (ICP), and it should be based on data from your existing customers, not assumptions about who you think should buy.
Pull a list of your best customers. Best means highest lifetime value, fastest sales cycle, highest retention, and strongest expansion revenue. Look for patterns across these accounts:
- Firmographic patterns: What industries are they in? How many employees? What revenue range? Where are they located? Public or private?
- Technographic patterns: What tools do they use? What CRM? What marketing platform? Are there specific technologies that correlate with being a good fit?
- Behavioral patterns: How did they find you? What content did they engage with before buying? How long was the sales cycle?
If you have 50 or more closed-won accounts, you have enough data to build a meaningful ICP. If you have fewer, supplement with qualitative input from your sales team about their best conversations.
The ICP Scoring Model
Turn your ICP into a quantitative scoring model. Here is a framework that works well:
Firmographic Fit (40% weight):
- Industry match: 0-10 points (exact match = 10, adjacent industry = 5, no match = 0)
- Company size match: 0-10 points (sweet spot range = 10, close = 5, way off = 0)
- Revenue match: 0-10 points (same scale)
- Geographic match: 0-10 points (target market = 10, secondary market = 5, excluded market = 0)
Technographic Fit (25% weight):
- Uses complementary technology: 0-10 points
- Uses competitor product: 0-10 points (displacement opportunity)
- Tech stack complexity matches: 0-10 points
Intent Signals (25% weight):
- Researching relevant topics: 0-10 points
- Visiting review sites for your category: 0-10 points
- Consuming competitor content: 0-10 points
Engagement History (10% weight):
- Previous website visits: 0-10 points
- Content downloads: 0-10 points
- Event attendance: 0-10 points
This is not a perfect model. No scoring model is. But it gives you a consistent, data-driven way to rank accounts rather than going with whoever the VP of Sales met at a conference last month.
Enriching Your Target Universe
Now comes the enrichment step. You need to identify the universe of companies that could potentially be good fits, then enrich them with the data your scoring model needs.
Building the Initial Universe
Start broad. If your ICP targets SaaS companies with 100-1000 employees in North America, that is thousands of potential accounts. Good. You want a large starting universe that you will narrow down through scoring.
Sources for your initial company universe:
- LinkedIn Sales Navigator company searches
- Industry databases and directories
- Your CRM (including closed-lost and dormant accounts)
- Trade show attendee lists and industry association membership directories
- Competitor customer lists (from case studies, reviews, job postings)
Enriching with Firmographic Data
For each company in your universe, enrich with the firmographic data your scoring model needs: employee count, revenue estimate, industry classification, headquarters location, founding date, growth trajectory, ownership structure.
Good enrichment tools provide most of this automatically. BetterEnrich cascades across 17+ data sources to maximize firmographic coverage, which is important because no single source has complete data on every company.
Enriching with Technographic Data
Technology stack data reveals what tools a company uses. This is gold for targeting because it tells you about compatibility, competitive displacement opportunities, and technical sophistication.
Key technographic data points to enrich:
- CRM system (Salesforce, HubSpot, Pipedrive, etc.)
- Marketing automation platform
- Sales engagement tools
- Data and analytics stack
- Industry-specific software
Layering Intent Data
Intent data shows which companies are actively researching topics related to your solution. This is the difference between a list of companies that could buy and a list of companies that might buy soon.
Intent data sources include:
- Bombora: cooperative intent data from 5,000+ publisher websites, tracking 12,000+ topics
- 6sense: AI-powered buying stage prediction
- G2: review site engagement signals
- Your own website: visitor identification via deanonymization tools
Companies showing 3 or more intent topics relevant to your solution convert at 3-5x the rate of cold accounts. That signal alone can dramatically improve your target list quality.
Scoring and Ranking
With enriched data in hand, apply your scoring model to every account in the universe. This produces a ranked list from highest-fit to lowest-fit.
Do not try to pursue every account that scores above zero. ABM works because of focus. The 79% of marketers who report higher ROI from ABM than any other marketing effort are focused on small, well-chosen lists, not massive spray-and-pray lists.
Recommended list sizes by team capacity:
- Small team (1-2 reps, 1 marketer): 25-50 accounts
- Mid-size team (3-5 reps, dedicated ABM marketer): 50-150 accounts
- Larger team (5+ reps, ABM team): 150-500 accounts
Within your list, create tiers:
- Tier 1 (top 10-20%): Highest scores. Full personalized outreach. Custom content. Executive engagement.
- Tier 2 (next 30%): Strong scores. Semi-personalized outreach. Industry-specific content.
- Tier 3 (remaining 50%): Good scores. Programmatic outreach. Scaled campaigns.
Enriching the Buying Committee
A target account list is not a list of companies. It is a list of companies with identified decision-makers. Once you have your accounts, you need to enrich with contact data for the buying committee at each one.
The average B2B buying committee includes 6-10 decision-makers. Key roles to identify and enrich:
- Economic buyer: The person who signs the check. Usually VP or C-level.
- Champion: The person who will advocate internally for your solution. Usually a director or senior manager.
- Technical evaluator: The person who assesses technical fit. Usually IT, engineering, or ops.
- End users: People who will actually use the product day to day.
- Legal/procurement: People who handle contracts and compliance.
For each person, enrich with verified work email and direct dial phone number. Waterfall enrichment shines here because buying committee members are often harder to find than standard contacts. The cascade across 17+ sources significantly improves the chance of finding valid contact data for each stakeholder.
Target coverage: at least 3-5 contacts per Tier 1 account, 2-3 per Tier 2, and at least 1 key contact per Tier 3.
Validating and Refreshing Your List
Your target account list is not a one-time exercise. It is a living document that needs regular validation and updates.
Monthly Activities
- Review account scores against new intent data (buying signals change)
- Add new accounts that fit ICP criteria (new companies, companies that grew into your sweet spot)
- Remove accounts that no longer fit (acquired, went out of business, already became customers)
- Verify contact data for Tier 1 accounts (people change jobs at 15-20% annually)
Quarterly Activities
- Re-run full ICP scoring with updated firmographic and technographic data
- Re-evaluate tier assignments based on engagement and pipeline progression
- Refresh all contact data through re-enrichment
- Analyze conversion rates by tier to validate scoring model accuracy
Annual Activities
- Revisit your ICP definition based on the past year of closed-won data
- Adjust scoring model weights if certain factors proved more or less predictive than expected
- Expand or contract your total account list based on team capacity changes
Common Mistakes in Account List Building
Using gut feel instead of data. The whole point of enrichment-driven account selection is objectivity. If leadership overrides the data to add pet accounts, your scoring model loses credibility.
Building too large a list. ABM diluted across 5,000 accounts is just marketing. Keep the list tight enough that every account gets meaningful attention.
Not enriching contacts. A list of company names without identified decision-makers is useless. The enrichment step for buying committee contacts is not optional.
Setting and forgetting. B2B data decays at 22.5% per year. A target account list that is not refreshed quarterly is actively degrading.
Ignoring intent data. Firmographic fit alone tells you who could buy. Intent data tells you who might buy soon. The combination is what makes ABM work.
Building a target account list is where ABM programs are won or lost. Get the data right, apply systematic scoring, enrich with real contact information, and keep it fresh. That foundation supports everything else your ABM program needs to succeed.
