Lorenz Heine is a co-founder of Babbel, the Berlin language-learning company. He has held the title Chief Innovation Officer.
Babbel began in 2007 as Lesson Nine GmbH. Heine started it with Markus Witte, Thomas Holl and Toine Diepstraten, four colleagues from a Berlin software company. In January 2008 the free community beta went live.
The company chose to charge for lessons instead of living on advertising. In 2013 it bought PlaySay, a San Francisco startup, to enter the US market. In 2023 it bought Toucan.
Leadership at the top changed in these years. Witte stepped down as CEO in 2019, returned in October 2024, and became Chairman of the Supervisory Board in mid-2025.
