The company was founded in 2007 by Or Offer in Tel-Aviv, Israel.[3] By 2009 SimilarWeb won the first Israeli SeedCamp, attracting the attention of international media and investors. The company raised its Series A round of $1.1 million[4] with the investment being led by Yossi Vardi, and Docor International Management. SimilarSites, a browser extension to help users find sites similar to those they are visiting, was launched later that year.

On September 24, 2013, the company closed a $6 million[5] Series B round led by David Alliance, Moshe Lichtman with the participation of existing investor Docor International Management.[6] On February 24, 2014, South Africa media giant Naspers invested $18 million into SimilarWeb and leading their Series C round.[7] Within a month, SimilarWeb used a part of the capital for the acquisition of Israeli early-stage company TapDog for a few million dollars in shares and cash, less than a year after TapDog was founded.[8] In November 2014, SimilarWeb announced that it had collected funds for its global expansion and enhancement of its mobile insights and mobile app platform. Alongside this move, Naspers and Lord David Alliance contributed $15 million in a series D investment.[9][10][citation needed] some of SimilarWeb's notable clients include PayPal, eBay Inc., Flipkart, Adidas and others[citation needed].

On December 10, 2015, SimilarWeb announced it had acquired Quettra, a Silicon Valley-based mobile intelligence startup, to boost its mobile operations.,[11] Quettra provided personalization tools for developers in return for detailed mobile telemetry data.

In July 2017, the company announced a $47M round of financing led by Viola Growth, Saban Ventures with participation from CE Ventures and existing investors.


SimilarWeb leverages in the world's largest panel, including hundreds of millions of devices worldwide to create an accurate estimation of everything happening in the digital world. For websites, this includes how traffic arrives to a website, what it does when it gets there and where it goes after. With mobile apps, it shows download and engagement data enabling visibility not just on which apps are on phones, but which are actually being used. [12][13][14] The panel is then filtered through a layer of advanced machine learning algorithms and data analysis processes and measured against the industry's largest learning set. SimilarWeb claims to have the industry's top R&D team in the sector with over 150 professionals working on advancing these systems.
