DataSend.ai vs Handelsregister: How to Find and Reach Companies in Germany

Introduction: Germany has 3.1 million companies. Handelsregister shows their names. DataSend.ai helps you reach out to them.

If you are looking for companies in Germany, you probably started at handelsregister.de — the official commercial register, which has been free and publicly accessible since August 2022. You can find the company name, legal form, headquarters, directors, and registration details there.

But what if you actually want to contact these companies and acquire them as clients? Email? Phone? Website? Industry? Revenue? None of this can be found in the Handelsregister. And this is where the crucial difference lies between a register and a lead generation platform.

1. Handelsregister: What it Offers and What it Doesn’t

Handelsregister (handelsregister.de) is a joint portal of all 16 German federal states. Since 2022, it has been accessible for free, without registration.

What you will find:

Company name and legal form (GmbH, AG, e.K., KG...). Headquarters and address. Names of directors and authorized signatories. Registration number (Handelsregisternummer). Founding documents and changes in the register. Share capital (for capital companies).

What you won’t find:

Email addresses. Phone numbers. Websites. Industry or classification of activity. Revenue, profit, or number of employees. Contact details for specific individuals. No way to directly reach out to companies.

Other limitations:

Search is basic — you can search by company name, registration number, or headquarters. No filtering by industry, size, revenue, or region. No bulk exports. No API for regular users. The German Unternehmensregister (unternehmensregister.de) offers some financial data, but also lacks contacts and outreach capabilities.

Handelsregister is a register — not a client acquisition tool. It is excellent for verifying whether a company exists and who represents it. But if you want to send emails, call them, or systematically reach out, the register won’t help you.

2. DataSend.ai: 3.1 Million German Companies with Contacts and Outreach Tools

DataSend.ai covers the German market with 3.1 million companies, of which 2.1 million have at least one verified contact detail — email, phone, or website.

What you will find for German companies:

Verified email addresses with deliverability checks. Phone numbers (distinguishing mobile/fixed line). Websites with Web Intelligence scores (website quality, speed, SSL, mobile optimization, e-shop detection). Industry (40+ categories). Region (all 16 Bundesländer). Registration details (Handelsregisternummer, Steuernummer, USt-IdNr.). Legal form.

What you can do with this data (directly in the platform):

Filter by industry, region, size, and other criteria — select exactly the companies that match your ideal customer profile. Launch a personalized email campaign with AI personalization. AI Grammar Variables automatically decline city and industry names in German — “im Bauwesen”, “in Berlin”, “für das Gesundheitswesen” — so that every email sounds natural and not like a mass message. Set up follow-up sequences that are automatically sent to companies that did not respond. Track responses in Unibox with AI classification — the system automatically recognizes whether the company is interested, what they want, and what you should do next. Move leads into the Pipeline and track the entire deal.

3. Direct Comparison

Number of companies: Handelsregister — all registered companies in Germany (exact number with active status unknown). DataSend.ai — 3.1 million companies, 2.1 million with verified contacts.

Contact details: Handelsregister — no emails, phones, or websites. DataSend.ai — verified emails, phones, and websites.

Filtering: Handelsregister — by company name, headquarters, or registration number. DataSend.ai — 20+ filters: industry, region (16 Bundesländer), revenue, employees, web score, type of company.

Email campaigns: Handelsregister — none. DataSend.ai — full email infrastructure with AI personalization, warmup, and follow-up sequences.

AI personalization in German: Handelsregister — does not address. DataSend.ai — AI Grammar Variables automatically generate correct grammatical forms: “im Bauwesen” (not “in Bauwesen”), “in Berlin” (not “in die Berlin”). For German with its grammatical cases, this is a crucial difference between an email that sounds human and an email that immediately reveals itself as a mass message.

CRM / Pipeline: Handelsregister — none. DataSend.ai — built-in pipeline with notes, stages, and priorities.

Price: Handelsregister — free. DataSend.ai — from $0 (free plan) with paid plans starting at $89/month.

4. When to Use Handelsregister

Handelsregister is the right choice when:

You need to verify whether a specific German company exists. You are looking for the name of a director or legal form. You need a registration number for a contract or invoice. You want to view founding documents or changes in the register.

For these purposes, Handelsregister is excellent and free. If your task is to verify a company, not to reach out to it — Handelsregister is sufficient.

5. When to Use DataSend.ai

DataSend.ai is the right choice when:

You want to find German companies by industry, region, and size. You need verified contact details — emails, phones, websites. You want to actively reach out to companies with personalized emails. You need your emails in German to sound natural (AI Grammar Variables). You want to track responses, follow-ups, and deals in one place.

If you want to find clients in Germany, reach out to them, and close deals — DataSend.ai is built for that.

6. The German Market: Why It’s Worth Reaching Out to Companies Directly

Germany is the largest economy in Europe with millions of companies actively looking for external suppliers. Medium-sized enterprises (Mittelstand) form the backbone of the German economy — and most of them do not have internal marketing or sales teams. They are used to collaborating with external partners.

At the same time, the German market is demanding in terms of communication quality. An email in poor German with grammatical errors will end up in the trash immediately. Therefore, AI personalization with the correct grammatical forms is not just an advantage — it is a necessity.

Conclusion

Handelsregister is a free register for verifying companies. DataSend.ai is a platform for finding and reaching out to them. Two different tools, two different purposes.

If you want to actively acquire clients in the German market, you need more than a register — you need verified contacts, email infrastructure, and AI that speaks German correctly.

Want to reach out to German companies? DataSend.ai — 3.1 million companies, 2.1 million verified contacts, AI personalization in German. Everything in one place.
