O&O Software Coupons & Offers - September 2026

O&O Software GmbH was established in 1997 in Berlin, Germany by Oliver Falkenthal and Olaf Kehrer. The idea for the name “O&O” originated back in 1991 in the form of O&O Systemtechnik GbR, a company offering software specifically for students whilst the two founders were still studying. The name “O&O” came about spontaneously, as both founders first names begin with the letter “O”. In 1998, on the 10th February to be exact, O&O Defrag V1.0 was released, and the company that you see today was born.
