As part of the most successful financial year in the company’s 30-year history, the operator saw betting stakes rise to over €2bn for the first time, a 30% rise.
The resulting €99.5m revenue also saw the company’s EBITDA margin rise to 22.4%, a 64% growth.
Interwetten notes its results are "particularly remarkable" due to the absence of a major football event within the calendar.
Dominik Beier joined Interwetten at the start of 2019 as the operator’s Speaker of the Board (equivalent title to CEO of the company), becoming the youngest in Interwetten's history.
Reflecting on his successful start, Beier said: "This great year 2019 is the result of fantastic teamwork and achievements across all company divisions.
"A record result, without a European or World Cup and in view of the major regulatory challenges, is absolutely extraordinary. Our size and structure enables us to work flexibly and quickly.
"For us, it is now important to continue to go full power; 2020 is a very important year, which will be marked by the product offensive, the European Football Championship and expansion into new, regulated, markets."
