Why segment companies before prospecting?

Segmenting companies by size, industry, and location is the most important step before any B2B prospecting campaign. Without segmentation, you send the same message to completely different companies — and response rates plummet. OpenView Partners shares pricing insights from 2,200 SaaS companies showing how deal sizes vary dramatically by company segment.

According to Forrester Research, teams that segment their database before contacting improve their response rate by 78%. It is not more work — it is working smarter.

The 3 essential B2B segmentation filters

Not all filters have the same impact. HubSpot predicts that AI will reshape marketing and customer segmentation in fundamental ways. These are the three filters that transform your prospecting:

Industry only
Useful but insufficient. Cannot distinguish a startup from a multinational.
Efficiency40%
Industry + size
Better: you adapt the message to the company type. But ignores geography.
Efficiency60%
Industry + manual location
You segment by area but the process is slow and error-prone.

How to segment in 4 steps

1

Define your segmentation criteria

Main industry, estimated size (by reviews/activity), and priority geographic area.

2

Generate the filtered database

Use the Business Finder to get companies meeting all 3 criteria. Download with email, phone, and social profiles.

3

Create sub-segments

Divide by city, neighborhood, or activity level. Each sub-segment gets a different message.

4

Adapt the message to each segment

Personalize mentioning something specific about their area or sector. Your ICP definition guides your tone.

Segmentation is not an extra step — it is the step that determines whether your campaign works or fails. A generic message gets ignored. A segmented message gets answered.

Segmentation criteria and their impact

Each filtering criterion adds precision to your prospecting. Eurostat's business demography statistics provide EU-wide data on enterprise birth rates, survival rates, and industry composition to inform your segmentation:

Criterion What it adds Impact on conversion
Industry / category Message relevance +35% response
Geographic location Proximity and local context +25% response
Size (reviews/activity) Alignment with your offer +40% conversion
Digital presence Prospect maturity +20% engagement
Google rating Quality and activity indicator +15% close rate
Selling to everyone is selling to no one. Segmentation is the weapon of closers
