Apptimize, a provider of app optimisation tools, raised $12.4 million in a new funding round, to “fuel continued global growth” of its technology.

“Mobile continues to be the dominant way consumers want to interact, so it’s important that businesses learn and adapt to customer preferences as quickly as possible,” said Nancy Hua, co-founder and CEO of Apptimize.

Apptimize, which helps businesses optimise, test and then deploy mobile apps, has now raised $18.5 million in total, and counts high profile names such as The Wall Street Journal, Vevo and Glassdoor among its client list.

Dafina Toncheva, who will join the board at Apptimize, on behalf of investor US Venture Partners (USVP), said in a statement she was “impressed by the long list of sophisticated mobile first businesses who see Apptimize as the path to stronger user engagement and increased monetisation of their native apps”.

The Series B round was led by US Venture Partners (USVP), with participation from other VC firms, including Glynn capital Management, Goldcrest Investments and Western Technology Investments.
