Or Offer is an Israeli entrepreneur and the founder and chief executive of the web-analytics company Similarweb.[1] He served in Oketz, the Israel Defense Forces canine unit, partly "in an outpost inside the Gaza strip" in the occupied territory, and has said that he founded Similarweb with friends from "an IDF elite technology unit".[2]
Military service
Offer told Ctech in 2021: "The IDF’s 8200 unit wanted to draft me because I was already a programmer, but I was not interested, back then, 8200 did not have the reputation it has now. Besides, I wanted to be a combat soldier", adding that he had hoped to join the special forces but "ended up in Oketz" (Unit 8200). He said: "During a big part of my service, I was caring for dogs in the south, in an outpost inside the Gaza strip. Being a dog operator is a unique position, even as a young soldier, you join experienced combat forces, you casually speak with brigadiers and lieutenants generals."[2] The interview does not give the dates of his service.
Similarweb
Offer told Ctech that he began Similarweb as a browser extension: "I convinced a friend of mine, who had just been released from an IDF elite technology unit, to come and help me with programming and he brought in a few more friends who had served with him in the unit, and in 2007 we founded the company." The friend and the unit were not named.[2] The company's 2021 registration statement says that "Or Offer founded our Company in 2009" and has been chief executive and a director since, that he was a founding partner of AfterDownload, bought by ironSource, and that he holds a degree from the Interdisciplinary Center Herzliya. It names Benjamin Seror as a co-founder and chief product officer.[1]
According to Ctech, Similarweb began trading on Nasdaq in May 2021 "in the midst of the latest round of fighting on the Gaza border", at a value of $1.6 billion, raising $180 million. Ctech also reported that Offer had started out in business in his parents' jewellery shops.[2]
