London – SimilarWeb, the new standard in digital insight and measurement, has successfully completed a Series D round of $15 million co-led by existing shareholders Naspers and Lord David Alliance. Combined with previous investments, SimilarWeb has raised a total of $40 million since 2009.

In 2013 SimilarWeb launched SimilarWeb Pro, the company’s paid platform for marketing intelligence, which today is being used by leading global organizations. Since launch, the company has achieved continual and significant growth in revenue and has become the new standard in web measurement.

With the new round of funding SimilarWeb plans to increase the pace of their global expansion. SimilarWeb will also use this investment to pursue an aggressive mobile strategy by expanding their mobile product capabilities, as well as targeted acquisitions in the mobile arena.

In 2014 SimilarWeb introduced its mobile strategy by integrating mobile web and app analysis insights into SimilarWeb products. In the coming weeks the company will achieve an important milestone with the launch of its mobile app engagement product that will reveal previously unknown insights into app usage, engagement, and retention. Early beta list registration for the new features is open to the public at the SimilarWeb App Engagement registration page.

The new product is part of SimilarWeb’s vision to offer total digital intelligence across all devices and global markets. SimilarWeb was the first provider to have integrated website, mobile web, and mobile apps data onto a single platform.
