Xsight Labs

Xsight Labs Ltd. (Hebrew: אקסייט לאבס בע"מ) is an Israeli fabless semiconductor startup that develops high-speed connectivity chips for data centers and hyperscale server farms. The company was founded in January 2017 by Guy Koren (CEO), Erez Sheizaf, and Gal Malach (CTO), all alumni of the chipmaker EZchip, which was sold to Mellanox in 2015. Avigdor Willenz, a prominent Israeli semiconductor entrepreneur and investor, serves as chairman and was the company's first investor. Xsight Labs focuses on switch and connectivity silicon for high-speed networking inside server farms. In December 2020 the company unveiled its first chip, the X1, fabricated in a 7-nanometer process. The X1 functions as a switch in server farms and supports connectivity of 12.8 to 25.6 terabits per second. In December 2025 the company reached an agreement with SpaceX to supply its X2 communications switch, manufactured by TSMC in a 5-nanometer process, for the V3 satellites of the Starlink project. The company has raised substantial venture capital. In May 2020 it raised $80 million, including from Intel Capital. In December 2020 it raised $116 million. By September 2022 total fundraising reached $220 million. By June 2026 total fundraising reached $430 million, with the last round (May 2021) reportedly at a $500 million valuation. In July 2026 the company raised about $300 million at a post-money valuation of about $2.8 billion, becoming a unicorn. In 2022 the company encountered difficulties that led to employee layoffs and the departure of Koren and Sheizaf from their operational roles (Sheizaf continued to serve as a director). Yossi Malka was appointed CEO in July 2022, having joined the company in May 2021 as chief operating officer. Xsight Labs remains a private, venture-backed company headquartered in Israel, selling into the global data-center and hyperscaler market.

Xsight Labs was founded in January 2017 by Guy Koren (CEO), Erez Sheizaf, and Gal Malach (CTO), all veterans of the Israeli chipmaker EZchip, which had been acquired by Mellanox in 2015. Avigdor Willenz, a well-known Israeli semiconductor entrepreneur and investor, became chairman and the company's first investor. The company set out to develop high-speed connectivity silicon for use in server farms. The company's early years were marked by significant venture fundraising. In May 2020 it raised $80 million, with participation from Intel Capital among others. In December 2020 it raised a further $116 million. That same month, Xsight Labs disclosed its first chip: the X1, fabricated in a 7-nanometer process. The X1 serves as a switch in server farms and supports connectivity of 12.8 to 25.6 terabits per second. In 2022 the company ran into difficulties that led to layoffs and the departure of founders Koren and Sheizaf from their operational roles; Sheizaf remained a director. In July 2022 Yossi Malka, who had joined the company in May 2021 as chief operating officer, was appointed CEO. By September 2022 cumulative fundraising had reached $220 million. The company continued to develop its switch silicon. In December 2025 Xsight Labs reached an agreement with SpaceX to supply its X2 communications switch, manufactured by TSMC in a 5-nanometer process, for the V3 satellites of the Starlink project — a notable design win in satellite communications. By June 2026 total fundraising had reached $430 million, with the most recent round (May 2021) having been done at a $500 million valuation. In July 2026 the company raised about $300 million at a post-money valuation of about $2.8 billion, making it a unicorn.
