Your list is your strategy. Without the right chords, you’ll never make music—or book meetings. Back in the day, crafting a killer account list was manual, expensive, and often as frustrating as herding cats (which I haven’t tried to do). But now? We have better tools, sharper data, and smarter frameworks. Let’s explore how to build a target account list that performs like a finely tuned orchestra or an expert cat hurder (I’m a paragraph in and I regret that analogy).

1. Clarify Your Ideal Customer Profile (ICP) – the Foundation of Focus
Begin with a clear, data-driven Ideal Customer Profile. Use:
- First-party CRM and MAP data, to pinpoint traits of your best customers (industry, company size, revenue, tech stack) — alignment between Sales and Marketing is key.
- Intent and engagement signals, like job postings, funding rounds or tech adoption — these act as proxies for buying readiness. Tools such as Demandbase, LinkedIn Sales Navigator, ZoomInfo, and MarketSizer make this easier.

2. Identify Accounts That Match Your ICP – Smarter, Not Harder
Once your ICP is nailed, build your list using:
- Demandbase / ZoomInfo / LinkedIn Sales Navigator for precise filtering.
- Clay, which draws from 50+ data providers (Crunchbase, Apollo, BuiltWith, RocketReach), layering filters to progressively narrow down high-fit companies, then enriches and scores them.

3. Prioritise Through Tiering & Scoring
Not all accounts are created equal. Focus first on the high-impact hitters:
- Tier your list by match, value and intent: High-fit, high-intent accounts deserve your time; others follow later.
- Score accounts using fit, engagement and intent — Clay and CRM platforms like HubSpot support this, enabling dynamic lists and prioritised outreach.
4. Elevate with Intelligence & Automation
You’ve got the list—now enrich it. Throw in email addresses, technographic data, and personalised signals.
- Clay again comes through with on-the-fly enrichment and AI-assisted research (think ‘Claygent’): build, score, enrich and sync—all without spreadsheets.
- Open-source Intelligence (OSINT) tools like Maltego, TheHarvester, Recon-ng or SpiderFoot can unearth hidden contact or infrastructure insights—great for manual digs, but there is something that says this isn’t the purpose these tools are for.
- HubSpot acquired data enrichment firm Clearbit which now powers their Breeze Intelligence feature set but this can get away from you without a decent eye on the credits.

5. Sync, Track & Iterate
You can’t just build a list, send emails and call it a day. ABM is built on rhythm, feedback and momentum.
- Automate CRM syncs (e.g., Clay → HubSpot) for instant list activation and seamless execution.
- Monitor conversions, engagement and pipeline impact, and iterate. Refresh your TAL quarterly—but keep no more than 20% turned over at once to maintain focus.
