change detection

Company Monitor is a module for observing selected companies and detecting significant changes in their data. Every night, the system downloads and structures the registered data. Instead of digging through scattered information, you get an ordered stream of events that shows what actually changed and when. This lets you react faster to signals that matter for sales, risk analysis, research, and process automation. In practice, Company Monitor turns registry data into clear, operational context for your team and systems.

We catch the changes before they catch you

Company Monitor tracks 29 types of events in registry data—from address changes and business suspensions to bankruptcy and changes in registration numbers. Each event is presented to you as a typed event with a severity and class, so you can immediately tell whether it's routine or a red flag.

Trade

A shipment is scheduled for Tuesday, packed Monday evening. On Monday your contractor files for bankruptcy — and you get the alert Tuesday morning, before the goods leave the warehouse and before you issue the invoice. You hold the shipment with a single decision. Without the alert, you would have found out only after the payment due date.

Finance

A client with an active leasing contract suspends operations and changes legal form. Instead of catching it at the quarterly portfolio review, you get the event the same day — and start the collections procedure before the installment becomes unrecoverable.

Severity: info notice warning high critical
COMPANY_BANKRUPTCY_STARTED critical

Bankruptcy proceedings were initiated against the company.

risk
COMPANY_TAX_IDENTITY_CHANGED critical

The company's tax identity number (NIP) changed.

COMPANY_LEGAL_FORM_CHANGED high

Real-world use cases.

Contractor monitoring

Detect supplier changes before they impact your business. Know immediately when a company changes address, suspends operations, or declares bankruptcy.

Compliance & KYC

Automatically detect changes in client companies relevant to regulatory compliance. Every event with a date and full context.

Risk management

Early warning signals — suspension, bankruptcy, change of legal form. React before the problem affects your business.

CRM data sync

Automatically sync company data changes with your system. No more outdated addresses and phone numbers.

Competitive intelligence

Monitor your competitors moves: new branches, business expansions, or changes in legal form. You'll catch signals of expansion as soon as they appear in the register—not delayed by media reports.

Sales timing

Treat events as buying signals: a new branch, resumed activity, or fresh contact data mark a company on the rise. Reach out exactly when the need peaks.

Alerts on your thresholds

No need to poll the API in a loop. Set alerts on selected event types or severity levels and receive only what matters.
