Why a targeted list beats a generic database

A sales rep who reaches out to a thousand random companies will close a different number of deals than one who approaches two hundred companies operating in exactly the right industry. Targeting is not a luxury — it is the foundation of efficient B2B sales. The same logic applies to marketing agencies building prospect lists for clients or HR teams looking for partner organisations.

The key insight is that data quality beats data volume. A targeted list of 300 companies with verified contacts will consistently outperform a broadcast to 10,000 entries from a stale database.

Step 1 – Choose your industry using NACE codes

The NACE classification system divides all economic activity into hundreds of industries. Every company in the commercial register carries one or more NACE codes. Selecting the right code is the first filter that separates your target segment from the noise.

  • Section (single letter, e.g. C = Manufacturing) is appropriate for broad awareness campaigns.
  • Three-digit code (e.g. 471 – Retail sale in non-specialised stores) provides medium granularity.
  • Five-digit code gives you the tightest possible segment, for example a specific type of manufacturer.

Tip: If you are unsure of the exact code, browse the NACE tree from the broadest section downward. Most B2B databases offer a full-text search across NACE labels to help you navigate quickly.

Step 2 – Filter by region and company size

A geographic filter is essential for field sales teams, local suppliers, or any campaign where physical proximity matters. Filtering by region keeps the list manageable and ensures you are only chasing reachable prospects.

  • Region: In the Czech Republic there are 14 regions (kraje). You can combine several — for example Jihomoravský and Zlínský to cover Moravia.
  • Company size: A filter on headcount or turnover separates micro-enterprises from mid-market and enterprise targets.
  • Legal form: Limited companies (s.r.o.), joint-stock companies (a.s.), and sole traders (OSVČ) behave differently in a sales conversation and deserve separate cadences.

Step 3 – Layer in VAT status and contact availability

Two criteria that are consistently underused in B2B prospecting can instantly lift your response rates:

  • VAT registration: A VAT-registered company is generally active and has exceeded a minimum turnover threshold. This single filter removes dormant or shell entities from your list. See VAT Payer Reliability in Czechia: What You Must Know.
  • Contact availability: Filter for companies that have a verified email or phone number. Even the most precisely targeted list is useless without a way to reach anyone.

Tools like databázekontaktu.cz, which covers 4.4 million Czech companies, let you combine all of these filters simultaneously and show a live count before you export — so you always know the size of your list upfront.

Step 4 – Export to CSV or sync with your CRM

Once your filters are set, the export of companies by industry is straightforward. CSV is compatible with Excel, Google Sheets, and virtually every CRM (HubSpot, Pipedrive, Salesforce). When importing:

  • Map the company registration number (IČO) to your CRM's unique identifier to avoid duplicates on re-imports.
  • Add a campaign tag (e.g. industry=manufacturing; region=JMK; date=2026-08) so you can track segment performance over time.
  • Save your filter as a template — in 3–6 months the data will have aged and you will want to refresh with a single click.

Step 5 – Keep the list fresh

Czech companies are created and dissolved every day. Contact details change, businesses enter insolvency, and registrations lapse. Working from a year-old list means reaching out to entities that no longer exist or paying for mail that bounces.

A good practice is a quarterly refresh: re-run the same filter, compare with your previous export, and add only new entries. An insolvency filter removes financially distressed companies before you invest sales time pursuing them.

Conclusion

A targeted company list built on NACE industry code, region, size, VAT status, and contact availability is the bedrock of any effective B2B acquisition campaign. The tighter the segment, the higher the response rate and the lower the cost per acquired customer. Start narrow, validate your conversion rates, and then expand the list — never the other way around. Data coverage and pricing are in the company database subscription section.
