Search companies with verified contact data, monitor changes on your watchlist — all built on live business registry data.
Query business registry and filter results to entities that actually have contact data — phone, email, or fax. No blanks, no dead ends. Every result is ready to act on with your chosen contact type.
Building a prospect list is tedious work — especially when most databases are incomplete or outdated. Search solves this at the source: every result contains at least one verified contact, directly from the registry. Filter by industry, location, registration date, and legal form — and get only companies you can actually call or email.
The contact parameter is required. Every result has at least one verified contact — phone, email, or fax. No empty records.

Add any company to your watchlist by NIP, REGON, or KRS. Every day the system compares fresh registry snapshots against the previous state and generates typed events for every detected change.
Manually tracking changes across companies is impossible at scale. Watchlist does it automatically — you watch the companies that matter to you, and the system tells you every day what changed. Name change, new address, suspension, bankruptcy filing — every event is described, categorized, and delivered with full context.
Watch your suppliers and business partners. Know immediately when a company changes its address, suspends operations, or files for bankruptcy.
Automatically detect changes in client companies relevant to regulatory compliance. Every event with a date and full context.
Early warning signals — suspension, bankruptcy, change of legal form. React before the problem affects your business.
Automatically sync company data changes with your system. No more outdated addresses and phone numbers.
