# Contact OutBIG

OutBIG is operated by a named company at a real address, and every message goes to a person rather than a ticket queue. Use the details below for anything to do with the board: a listing that should be corrected or removed, a payment or refund question, a report about a link that breaks the rules, a press or partnership enquiry, or a question about the public API. There is no support chat and no phone tree — email is the fastest route, and the postal address below is the one on file in the Austrian company register.

## Postal address

Ostheimer OG  
Fabriksgasse 20  
2230 Gänserndorf  
Österreich  

## Email and phone

- Email: office@ostheimer.at
- Phone: +43 (0)699 1726 3544

Email is normally answered within two business days, in English or German. Please include the exact listing address (for example https://outbig.bid/en/product/example.com) and, for anything about a payment, the Stripe receipt or the email address used at checkout — that is enough to find the transaction without asking you for card details, which we neither see nor store.

If you are the owner of a website or profile that appears on the board as an unclaimed listing and you would rather it were not there, say so in one line and it will be removed; no proof of ownership is required for a removal request. Requests to remove a paid listing, to correct a title or image, or to exercise a data-protection right under the GDPR go to the same address and are handled by the operator named in the imprint.
