Kennet, which works out of London and Silicon Valley, will invest $12.5m (£7.8m) with the rest coming from existing German investors Tengelmann Ventures and High-Tech Gründerfonds.
The investment will be used for the Berlin-based company’s continued expansion, with offices already in London, Madrid, Paris and New York.
It will also be invested into Trademob's app advertising technology. Since its official launch in November 2011, the company's platform has delivered performance campaigns to help app marketers increase user retention, in?app engagement and app store ranking. Since then, Trademob says, it has experienced double?digit monthly revenue growth.
Michael Elias, managing director at Kennet, and Hillel Zidel, director at Kennet, will join Trademob’s board of directors. Zidel said: “Trademob has rapidly developed a leadership position in the large and fast-growing market for app marketing. What the team have developed over the last two years is hugely impressive, and we're excited to be working together to create a global market leader.”
Trademob says it can provide advertisers with access to more than 100 mobile ad networks, reaching more than 500m mobile users in 190 countries. Its clients include eBay Classifieds, Booking.com and Universal Music.
