Monitor Danish companies with notifications

Companies change all the time — new board members, ownership transfers, address moves, filed financial statements. If you follow competitors, suppliers, or portfolio companies, it's impossible to check them all manually. companydata.dk's monitoring feature watches for you and sends a notification when something changes.

What events can you monitor?

Monitoring covers eight categories of changes that together give a complete picture of a company's development:

• Company status — changes such as dissolution, bankruptcy, compulsory dissolution, or resumption
• Ownership — changes to the ownership structure, new or departed owners
• Board — new board members, departed members, or chairperson changes
• Directors — changes to the registered management
• Financial statements — new annual reports or financial statements filed with the Danish Business Authority
• Announcements — new official announcements
• Address — relocation of the company's registered address
• Contact information — changes to phone number or email

How to add companies to monitoring

You can start monitoring a company directly from its company page — click the monitor button, and you'll receive future notifications. If you have a list of companies in the Lists feature, you can bulk-subscribe the entire list to monitoring with one click. You can monitor up to 100 companies at the same time.

Choose how you get notified

You decide how often you want to receive email notifications:

• Immediate — one email per change, as soon as it's detected
• Daily digest — one summary email per day with all changes
• Weekly digest — one summary email per week

Daily or weekly digest works for most users. Choose immediate if you need to react quickly — for example, to bankruptcy notices or ownership changes.

Webhooks for automation

Need changes pushed to your own system? Set up a webhook, and companydata.dk sends a JSON request to your URL every time a change occurs. Webhooks are always delivered immediately — there is no digest option.

• Up to 5 webhook endpoints
• HMAC signature verification for secure delivery
• Automatic deactivation after 10 consecutive failures
• JSON payload with event details

The monitoring dashboard

On the monitoring page you see a combined timeline of all detected changes across your monitored companies. You can filter the timeline by event type — for example, only show ownership changes or new financial statements. Each event links directly to the relevant company page.

Practical use cases

• Competitor monitoring — get notified about management changes, new financials, or status changes at your competitors
• Portfolio management — keep tabs on investments or subsidiaries without checking them manually
• Supplier risk — catch early warning signs at critical suppliers, such as address changes or bankruptcy status
• Due diligence — follow companies during an ongoing evaluation and get notified about new information
