Israeli startups raise over $1.6 billion in December, marking strongest funding month since 2022
Large cybersecurity and AI financings drive the best month of 2025.
Israeli startups raised $1.635 billion across 22 funding rounds in December, marking the strongest month for venture funding in the country since 2022 and the highest monthly total recorded this year.
Several late-stage financings, alongside a steady flow of early-stage deals, combined to produce a level of activity not seen in three years.
The largest single round came from Cyera, the data security company, which raised $400 million at a $9 billion valuation in a Blackstone-led round, increasing its valuation sixfold in little more than a year. The deal alone accounted for nearly a quarter of the month’s total funding.
Another major contributor was Eon, which raised $300 million in a Series D round at a $4 billion valuation, bringing its total funding to more than $500 million since emerging from stealth last year.
Cybersecurity dominated the funding landscape, continuing a long-running trend in Israeli tech. In addition to Cyera, Vega raised $120 million in a Series B round, valuing the two-year-old company at $700 million, while 7AI, founded by former Cybereason executives, secured $130 million in a Series A round just ten months after exiting stealth. Zafran raised $60 million, doubling its valuation, while Act Security closed a rapid $40 million Series A only four months after a $20 million Seed round.
Healthcare and life sciences also featured. Syremis raised $165 million in a Series A to develop treatments for schizophrenia and other severe mental illnesses.
Artificial intelligence-focused startups attracted sustained interest across multiple stages. Port raised $100 million in a Series C at an $800 million valuation to support AI agents across software development, while Quantum Art, a Weizmann Institute spin-off, raised $100 million to scale full-stack quantum systems.
