If you invite friends to Ostrom with your referral code, you will both receive 50€. As soon as your two contracts are officially confirmed and delivered, you will receive your bonus.

We'll add your bonus to your Ostrom Wallet so you can use it either on your next bill with a 50€ credit or in our store as a 100€ voucher.

Please consider that there are no monthly invoices/bills - only interim and yearly invoices.
