Ofer Klein

Klein has described himself as a former Israel Defense Forces helicopter pilot and an avid kitesurfer, likening the adrenaline rush to being the founding CEO of a fast-growing security startup. He calls himself a serial entrepreneur with extensive experience building and growing go-to-market teams at SaaS companies in the United States.⁠[1][1][2]

In 2016, Klein was the founder and chief executive of Kwik, a Tel Aviv-based internet of things startup he founded with chief technology officer Shlomi Atias. Kwik made smart ordering buttons similar to Amazon Dash buttons that let consumers order products from home with a press, working at the time with brands such as Domino’s, Budweiser and Huggies; the buttons were free for consumers, and Kwik took a cut of each transaction.⁠[3][3][4][4][3]

On June 21, 2016, Kwik announced a $3 million seed round led by Norwest Venture Partners, with SeventySix Capital participating, and planned to expand to the United States after beta testing in Israel. Klein said at the time that “any product which is a repeated service” was ripe for a button, so that coffee, pet food or even taxis could be ordered with a tap, and that physical buttons were more convenient than smartphone apps.⁠[3][5][4][3][3]

In 2020, Klein co-founded Reco with Gal NakashGal NakashGal Nakash is an Israeli cybersecurity practitioner and the co-founder and chief product officer of the cybersecurity company Reco. Before joining Reco he led research at Israel’s Office of the Prime Minister; at Reco he is responsible for product and writes about AI agent security.Open the full entry and Tal ShapiraTal ShapiraTal Shapira is an Israeli computer networking and cybersecurity researcher and the co-founder and chief technology officer of the cybersecurity company Reco; his academic research focuses on using deep learning for encrypted traffic classification and IP hijack detection.Open the full entry and became its chief executive; it was his second startup after Kwik. By his account, the three developed the platform and AI algorithm for the Israeli government’s counterintelligence work while serving in Israel, and after that success productized it in 2020.⁠[6][6][1]

On June 3, 2022, Reco announced a $30 million Series A round, and Klein said the proceeds would go toward product development and go-to-market efforts. He argued at the time that the distributed workforce was increasing the number of collaboration tools in use at organizations, each of which introduced new security risk.⁠[6][6]

In a June 2024 interview, Klein said Reco was based in the United States with research and development in Israel, and that of his two co-founders, one was an AI PhD and the other had managed a vulnerability research group. He said Reco connects to SaaS applications’ metadata through APIs with read-only access to build a graph that analyzes interactions among identities, applications and data in real time, and argued that SaaS had become the fastest-growing attack surface over the previous year.⁠[7][7][7][7][7][7]

When Reco announced $25 million in additional funding in April 2025, Klein was based in Orlando in the United States. He said AI and generative AI agents were very valuable to businesses and could no longer be blocked, and that banks, insurance companies and healthcare organizations were starting to adopt them, but only with the right visibility and security in place.⁠[8][8]

On November 26, 2025, Klein published the article “The Hidden Risks of Shadow AI” on Unite.AI. In a December interview with CEOCFO Magazine, he said Reco had been around for five years, had grown fivefold the previous year and expected about fourfold growth that year, and believed its technology was about two years ahead of competitors; he also said the AWS chief executive had featured Reco among the most innovative products in his keynote at that month’s re:Invent conference, and that Reco operated mainly in the United States.⁠[9][10][10][10][10][10]

When Reco announced a $30 million Series B round in February 2026, Klein said enterprises were consuming AI mainly through SaaS, whether as AI applications, agents embedded in existing platforms or AI-powered integrations connecting business systems, and that this shift was driving the company’s rapid growth.⁠[11]

When Reco announced $55 million in additional funding on September 29, 2026, Klein said AT&TAT&TAT&T (AT&T Inc.) is a telecommunications company headquartered in Dallas, Texas. Its predecessor was SBC Communications, a regional holding company created in the 1984 breakup of the Bell System; SBC merged with the original AT&T Corp. in 2005 and adopted its name, and it has since operated a nationwide wireless network and fiber broadband, at one time also owning DIRECTV and WarnerMedia.Open the full entry’s participation as both a customer and strategic investor reflected the need for security that follows agents across enterprise ecosystems. He also said the company’s valuation had “more than doubled” since the Series B was announced in February, vaguely estimating it in the “high hundreds of millions” without giving specifics, and that the biggest change over the previous year was that companies were building and deploying AI agents faster than they could keep track of them.⁠[12][13][13]
