# Tier-1 Account List Building

A Tier 1 list is 5-15 named accounts that get full 1-to-1 ABM treatment. Every account on this list should be worth a meaningful percentage of your quarterly target. If the list has 30 accounts on it, it's not Tier 1. It's a segment with a Tier 1 label.

## What Makes an Account Tier 1

An account earns Tier 1 when it passes all four criteria:

| Criterion | Threshold | Why it matters |
|-----------|-----------|---------------|
| Deal size potential | ≥ 5x average ACV | 1-to-1 ABM costs $1,000-5,000 per account. The deal must justify the spend |
| ICP fit score | Top decile of your ICP scoring model | Tier 1 accounts should be the best possible fit, not just "good enough" |
| Active signal | At least one Tier 1 signal in the last 90 days | Without urgency, even perfect-fit accounts don't convert on ABM timelines |
| Accessible committee | ≥ 3 identified contacts across 2+ functions | Can't run 1-to-1 ABM if you can't reach the buyers |

If an account fails any single criterion, it's Tier 2 at best. Tier 1 is a high bar by design. Lowering the bar dilutes the investment and the results.

## The Build Process

### Step 1: Generate the long list (50-100 candidates)

Start wide. Pull candidate accounts from multiple sources and merge into one list before filtering.

**Source priority order:**

| Source | Why it's first | Expected yield |
|--------|---------------|---------------|
| CRM closed-lost (last 12 months) | Known pain, known contacts, known objections. Highest-quality starting point | 5-15 candidates |
| CRM stalled opportunities | Deals that went dark. May reactivate with a new signal or angle | 3-10 candidates |
| Customer look-alikes | Model your top 10 customers by firmographics, technographics, and use case. Find twins | 10-20 candidates |
| Intent data (6sense, Bombora, G2) | Accounts actively researching your category or competitors | 10-30 candidates |
| Sales team nominations | Reps know accounts they've been prospecting or hearing about | 5-15 candidates |
| Inbound engaged accounts | Visited pricing page, attended webinar, downloaded content but didn't convert | 5-10 candidates |
| LinkedIn Sales Nav saved searches | ICP-matched accounts with recent activity | 10-20 candidates |
| Competitor customer lists | G2 reviews, case studies, integration directories of competitors | 5-15 candidates |

**Long list rules:**
- Deduplicate across sources. The same account appearing in 3+ sources is a positive signal. Note the overlap
- Remove existing customers. Obvious but missed often when pulling from multiple systems
- Remove accounts with active open opportunities. ABM and live deals running simultaneously creates confusion. Let the deal play out
- Remove accounts in active competitor contracts with 12+ months remaining (if knowable). Timing isn't right for ABM. Add to long-term nurture
- Target 50-100 candidates. Below 50 means you're being too narrow too early. Above 100 means your sources are too broad

### Step 2: Score and rank (100 → 30)

Apply a scoring model to cut the long list in half. Score on three dimensions.

**Dimension 1: Fit score (0-30 points)**

| Factor | 0 | 10 | 20 | 30 |
|--------|---|-----|-----|-----|
| Company size | Outside range | Edge of range | Mid-range | Sweet spot |
| Industry | Adjacent vertical | Relevant vertical | Core vertical, some usage | Core vertical, proven use case |
| Tech stack | Incompatible | Partially compatible | Compatible, no integration yet | Uses tools you integrate with |
| Deal size potential | 1-2x ACV | 2-3x ACV | 3-5x ACV | 5x+ ACV |

**Dimension 2: Signal score (0-30 points)**

| Factor | 0 | 10 | 20 | 30 |
|--------|---|-----|-----|-----|
| Signal tier | No signal | Tier 3 only | Tier 2 signal | Tier 1 signal |
| Signal recency | > 6 months | 3-6 months | 1-3 months | Last 30 days |
| Signal stacking | None | 1 signal | 2 signals | 3+ signals from different categories |

**Dimension 3: Accessibility score (0-20 points)**

| Factor | 0 | 5 | 10 | 20 |
|--------|---|---|-----|-----|
| Contacts identified | 0-1 | 2 | 3-4 | 5+ across 2+ functions |
| Prior relationship | None | Weak (same event, same community) | Mutual connection | Direct connection or prior engagement |
| LinkedIn activity | Dark profiles | Occasional | Active | Frequent poster on relevant topics |

**Total: 80 points possible.** Rank all candidates by score. Take the top 30.

### Step 3: Deep-qualify (30 → 10-15)

The scoring model gets you to 30. Human judgment gets you to 10-15. This step requires marketing and sales leadership together.

**For each of the top 30, answer:**

1. **Is the signal real?** Verify the signal hasn't expired. A funding round announced 6 months ago with no subsequent hiring may have been a bridge round, not a growth round
2. **Can we win?** Is there an incumbent? Are they happy with it? Is a competitor already in a deal here? If yes, what's your realistic angle?
3. **Is the timing right?** Even with a signal, some accounts are in planning mode (H2 budget planning) or freeze mode (post-layoff). Will the buying window be open in the next 90 days?
4. **Do we have an angle?** Can you articulate in one sentence why this account should talk to you, referencing something specific about them? If not, you don't have an angle yet
5. **Is there organizational will?** Does your sales team want to work this account? Does the AE have capacity? An ABM account that nobody on the sales side will follow up on is a wasted investment

**Disqualify if:**
- Signal is stale (> 90 days with no secondary signal)
- An entrenched competitor with a happy customer (confirmed via G2 reviews or rep intel)
- ACV potential < 3x average after deeper analysis
- Zero accessible contacts after enrichment attempts
- No AE willing to own the account

**Target: 10-15 accounts.** This is your Tier 1 list. If you can't cut to 15, you're not being selective enough.

### Step 4: Enrich each account

For every account that makes the Tier 1 list, build a light account brief before campaign launch. This is not the full deep dive (see account-research-deep-dive skill). It's the minimum viable research.

**Per-account enrichment checklist (15-20 min each):**

- [ ] Company snapshot confirmed (size, stage, funding, vertical)
- [ ] Problem hypothesis written (one paragraph)
- [ ] Top signal documented with source and date
- [ ] 3-5 buying committee contacts identified with LinkedIn URLs
- [ ] Champion candidate identified with personalization token
- [ ] Economic buyer identified
- [ ] Incumbent/competitive tool noted
- [ ] Recommended outreach angle written (2 sentences)

## List Composition Rules

### Diversification

Don't put all Tier 1 accounts in one basket.

- **Industry mix:** No single vertical should exceed 40% of the Tier 1 list. If all 10 accounts are fintech, a fintech downturn wipes your pipeline
- **Size mix:** Include a range of company sizes within your ICP. Don't exclusively target the largest companies. Mid-range accounts close faster
- **Signal mix:** Don't build the list entirely around one signal type (all funding rounds, all leadership changes). Diversify signals to diversify timing
- **Geography mix:** If you sell across regions, represent each region. Territory reps need accounts to work

### Concentration

Some concentration is intentional and good.

- **Cluster overlap:** If 5 Tier 1 accounts share a trait (same vertical + same stage), you can run a combined 1-to-few surround campaign while still giving each account 1-to-1 outreach. Efficient budget use
- **Event alignment:** If 3 Tier 1 accounts will be at the same conference, that's a concentration advantage. Plan meetings, dinners, and in-person touches around the event

## Governance

### Who owns the list

| Stakeholder | Role | Decision rights |
|-------------|------|----------------|
| Marketing (ABM lead) | Builds the list, runs the scoring model, manages the surround campaign | Proposes the list. Owns the methodology |
| Sales leadership (VP/Director) | Validates accounts, assigns AEs, commits to follow-through | Approves or rejects accounts. Cannot add accounts without data justification |
| AEs / Account owners | Provide field intel, own direct outreach, run meetings | Can flag accounts as wrong-fit. Cannot unilaterally add accounts |
| RevOps | Maintains scoring model, provides data, tracks results | Maintains the infrastructure. Resolves data conflicts |

**Governance rules:**
- Marketing proposes. Sales approves. Neither can unilaterally set the list
- "My VP wants us to target [logo]" is not a valid addition without scoring data. Political additions get scored like every other candidate. If they pass, great. If not, document why and present the data
- Quarterly list review is mandatory. Remove accounts that completed campaigns with no engagement. Add new candidates that surfaced since the last review
- Changes between reviews require agreement from both marketing and sales. No silent additions or removals

### List lifecycle

| Event | Action | Timing |
|-------|--------|--------|
| Initial list build | Full process (Steps 1-4) | Once per quarter |
| Mid-quarter review | Check signal freshness, remove zero-engagement accounts, add 1-2 new candidates | Month 2 of quarter |
| End-of-quarter review | Full results analysis. Which accounts converted? Which didn't? Why? Inform next quarter's list | Last week of quarter |
| Account completes campaign with no engagement | Remove from Tier 1. Move to Tier 2 or nurture. Do not recycle to Tier 1 for 6 months | As campaigns complete |
| New high-value signal on a non-listed account | Fast-track through scoring. Add to Tier 1 if it passes all 4 criteria | As signals arise |

## Common List-Building Mistakes

| Mistake | Why it fails | Fix |
|---------|-------------|-----|
| List of 30+ accounts labeled "Tier 1" | Resources spread too thin. No account gets true 1-to-1 treatment | Hard cap at 15. Move the rest to Tier 2 |
| Built entirely from sales nominations | Political bias. Logo-chasing. No data backing | Nominations are one source. Run every nomination through the scoring model |
| Built entirely from intent data | High false-positive rate. Intent without fit = wasted effort | Layer intent on top of ICP fit. Never use intent as the sole selector |
| No signal requirement | List is full of "someday" accounts with no urgency | Require at least one Tier 1 or Tier 2 signal. No signal, no Tier 1 |
| Never refreshed | Signals decay. Contacts leave. Priorities shift | Quarterly rebuild. Mid-quarter signal check |
| Same list recycled quarter after quarter | If they didn't engage in Q1, repeating the exact same play in Q2 won't work | Change the angle, the signal, or the account. Repeating failed plays is not persistence, it's waste |
| No AE assignment | ABM generates surround + outreach but nobody follows up on meetings | Every Tier 1 account must have a named AE who has agreed to own it before the campaign starts |

## Measuring List Quality

Track these after each quarterly cycle:

| Metric | Good | Acceptable | Poor |
|--------|------|-----------|------|
| Engagement rate (% of Tier 1 accounts with any response) | > 50% | 30-50% | < 30% |
| Meeting rate (% of Tier 1 accounts with a meeting booked) | > 25% | 15-25% | < 15% |
| Opportunity rate (% of Tier 1 accounts with an opp created) | > 15% | 8-15% | < 8% |
| Pipeline per account | > $100K (if avg ACV ~$50K) | $50-100K | < $50K |
| Cost per meeting | < $500 | $500-1,500 | > $1,500 |

If engagement rate is below 30%, the list is wrong. Don't blame the campaign. Fix the selection.

## Anti-Pattern Check

- Tier 1 list has 25 accounts. That's Tier 2 with a Tier 1 label. Cut to 15 or admit it's 1-to-few
- Every account on the list is a Fortune 500 logo. Logo prestige doesn't equal deal probability. Score on fit and signal, not brand
- The list hasn't changed in 3 quarters. Markets move. Signals expire. A static list is a stale list
- No account on the list has a signal less than 90 days old. The list is cold. Refresh signals or replace accounts
- AEs weren't consulted during list build. They won't follow up on accounts they didn't agree to own. Joint ownership or it fails
- The list was built in a spreadsheet and never loaded into CRM. If it's not in the system, it doesn't get tracked, reported, or actioned. Load it Day 1
- Every account is in the same vertical. One vertical downturn = entire Tier 1 pipeline gone. Diversify
