The best company identification software is devilishly hard to identify.

At Partout, we're increasingly asked the same question. Which company identification software works best for our situation? Or, just as often, whether the tooling someone uses today still suits the market their organisation operates in. These questions don't only come from new clients, but especially from teams that have been working with an identification tool for some time and have doubts about what they're seeing.
In those conversations, we notice there is rarely one right answer. Company identification software differs greatly by vendor, by market and by how it is used. What works well for an organisation focused on the Netherlands may turn out less well for a company with international ambitions. In practice, the choice is often based on a demo or an agency's advice.

This article was written to bring more clarity. Not by naming one company identification tool as the best choice, but by explaining what company identification is, how this software works and why the differences in performance between these tools can be so large. That includes an important principle we stress in almost every project: you never make a choice based on a single company identification tool. Only by testing several vendors side by side can you see what suits your site traffic, market and goals.

What is company identification software?

Company identification software tries to give you insight into which organisations visit your website. Standard site statistics show how many visitors you have and which pages they view; company identification goes a step further. The aim is to link anonymous visitors to a company name and additional company information.

It is important to be clear straight away about what this is not. It isn't about identifying individuals, and it isn't conclusive proof either. Company identification works with signals and probabilities. The software gives an indication of which company is behind a visit, not absolute certainty.

Company identification software works by identifying companies through exclusion. Proprietary algorithms continuously establish which company a visit is not. Through this systematic elimination, the software can ultimately give a reliable indication of which company is actually behind the website visit.

For B2B marketers, this insight is valuable because it helps you better understand who you're reaching. Are you mainly seeing companies from the target audience you had in mind, or not? Do certain sectors show up more often than expected? And do your marketing activities match the companies that actually turn up on your website?

Why tools show such different results

If you implement two vendors of company identification software on your website at the same time, you'll find in practice that they often identify and display different companies.

That feels confusing and quickly raises the question of which of the two is right. In practice, the difference is easy to explain.

Every company identification software vendor makes its own choices. Those choices concern data sources, how signals are combined and how strict the software is about displaying a match. Some tools prefer to show more, even when certainty is lower. Other tools are more cautious and only show companies they can link to a visit with greater confidence.

That means more identifications aren't automatically better. A list with lots of companies may look appealing, but if it contains many doubtful cases, it costs time and frustration in practice.

Under the bonnet: how company identification works

To properly understand the differences, it helps to know how company identification works at a basic level.

From website visit to company name

Almost all tools start from the same point. A visitor lands on a website and leaves technical traces, such as an IP address and browser information. That IP address is often the first clue for linking a visit to an organisation.

Making that link with an IP address is more complicated than it sounds. Many companies share networks, employees work from home and internet providers use shared infrastructure. As a result, one IP address can belong to several organisations, or cannot be clearly attributed to any of them.

Data sources and enrichment

Besides technical signals, tools use large databases of company information. Each vendor builds and maintains such a database in its own way.

The difference lies in how large that database is, how up to date it is kept and how much additional information is linked to it. Some tools focus mainly on identification, while others also add company profiles, sector information or signals.

Matching is easy, weeding out errors is hard

An important point several vendors make is that creating a match isn't the hardest part. The real work lies in preventing false matches. Think of internet providers, shared office buildings or large organisations that are visible in many places.

Filtering out situations like these requires smart algorithms and a lot of historical data. That is exactly where the biggest differences between tools arise. Some choose to show something sooner, while others wait until there are enough signals to be more certain.

The company identification software we looked at

A number of names come up regularly in conversations with clients and vendors. In this article, we discuss three of them, not to rank them, but to better understand their positioning.

LeadInfo

LeadInfo originated in the Netherlands and the Benelux, where B2B organisations have been using it for quite some time. In recent years, its coverage has been extended to other countries. There is a strong emphasis on improving accuracy, partly by combining identification with form data.

LeadInfo is used for both marketing and sales purposes. Its success depends heavily on how the tool is set up and followed up. Organisations that actively use the data and integrate it into their processes clearly get more value out of it.

Prospect Pro

Prospect Pro grew out of a strong focus on the Dutch market. The emphasis is on up-to-date company data and carefully filtering out doubtful cases. In conversations with this vendor, it is clear that they would rather show fewer matches than display uncertain ones.

This approach suits organisations that operate mainly in the Netherlands and value the identification of small and medium-sized companies. International coverage is in development, but will only be rolled out more widely once it meets the same quality standards.

Dealfront

Dealfront, of which Leadfeeder is part, explicitly targets a broader market. Its strength lies mainly in Europe and the United States. Besides identification, the platform offers extensive company profiles and additional signals.

This approach is a good fit for organisations that operate in several countries and need consistent company information. For very local markets, a specialised player can sometimes offer more detail, but for scale and breadth, Dealfront is often a logical option.

There are of course more company identification software vendors on the market. Without conversations with these vendors and the context they bring, we have chosen not to assess them in detail here. The same principle does apply to all these tools, though: testing in your own situation is always necessary.

Which company identification software makes sense for which market?

The choice of company identification software depends heavily on the market you operate in.

Focus on the Netherlands

For organisations that focus mainly on the Netherlands, local coverage is important. Smaller companies and SMEs are especially relevant here. Tools with a strong Dutch base often have an advantage, because their data sources and algorithms are better suited to this market.

Focus on Europe

The quality of company data differs by country. In such a situation, a tool with a strong European presence is often more practical, even if that means identification per country is slightly less in-depth.

Global focus

Global identification calls for realistic expectations. No tool identifies equally much, equally well, everywhere. Large organisations are easier to identify than smaller local companies. In this context, combining signals becomes more important than relying on a single source.

Ask yourself these 3 questions to make a choice

Besides ProspectPro, Leadinfo and Dealfront, there are more company identification tools available, each with its own strengths. Snitcher focuses on ease of use and quick integrations with popular CRM tools. Lead Forensics has a strong presence in the United Kingdom and the United States, with extensive reporting features. Salesfeed is a Dutch tool focused on local identification and website personalisation. Albacross is particularly strong in Scandinavia and offers features for account-based marketing. Clearbit and ZoomInfo are mainly suitable for organisations active in the US that need advanced data enrichment or sales intelligence.

Because of these differences, it is important not to base your choice only on demo data or identification rates, but on the specific situation your organisation is in. Ask yourself these three questions

Step 1: Where is your market?

• Benelux / Netherlands → Choose a tool with strong local data sources, such as ProspectPro, Leadinfo or Salesfeed.
• Europe → Choose a tool with European coverage and European hosting, such as Dealfront or Albacross.
• US or global → Look at international players such as Lead Forensics, Clearbit or ZoomInfo.

Step 2: How important is GDPR compliance?

• Strictly necessary → Use a tool that works without cookies, processes no personal data and stores data exclusively within the EU, such as Leadinfo, Dealfront or ProspectPro.
• Less strict → Tools with broader functionality or US hosting may then also be suitable (such as Clearbit or Lead Forensics).

Step 3: Do you work with an ICP approach or account-based marketing?

• Yes → Choose a tool that supports your own lists or segments, such as ProspectPro or Dealfront.
• No → Choose a tool based on identification rate, ease of use and integration options.

Step 4: What is your budget?

• Say you have to choose and your market is the Benelux: you'll probably end up with ProspectPro or Leadinfo. 

Common misconceptions about company identification software

In practice, we see a number of assumptions come up regularly. More identifications don't automatically mean more value. The tool itself doesn't determine success; how you use the data does. And you don't make a choice once, because tools keep evolving.

Also, what works well for another organisation won't automatically work for you. Differences in target audience, traffic and market mean every situation is different.

4 takeaways

1. Almost all company identification software vendors focus on quality rather than quantity, because false matches cost more than they deliver.
2. Company identification software is continually improved through new data sources and algorithms. What works well today may be different in six months.
3. No tool is equally strong everywhere. The geographical market you operate in has a big influence on what you can expect.
4. The only way to make a good choice is to test for yourself and to repeat that regularly. Only then will you see what suits your situation.

Note: we also put the questions discussed in this article to various AI tools. Their answers differ from what you read here, simply because these systems have no access to non-public data and practical experience. This article is based on conversations with vendors and hands-on experience. Our role is to explain how tools work, which questions you should ask yourself and how to run a fair comparison. In practice, that often means we run several company identification software vendors side by side and look at what the results mean together with marketing and sales. We're always clear about one thing: our situation isn't automatically yours.
