Startup brief
Sovereign Plays and Big-Ticket Backing
Israeli founders rebuff multibillion-dollar takeovers and secure major institutional capital across AI, cybersecurity, and secondary liquidity.
Startup
Upwind walked away from Datadog's $4B buyout to raise $300M independently — top-tier Israeli cyber founders are holding out for standalone public market dominance.
BackgroundUpwind was founded by serial entrepreneur Amiram Shachar and former Spot.io executives to deliver unified runtime protection across distributed cloud and AI architectures. The decision to rebuff a multi-billion-dollar exit reflects intense venture confidence in sovereign Israeli enterprise cybersecurity platforms.
- Datadog submitted the multi-billion-dollar proposal to integrate Upwind's runtime cloud telemetry into its infrastructure monitoring software suite, seeking an immediate edge over rival security vendors.
- Upwind's concurrent $300M financing positions the startup among Israel's most valuable privately held software firms as enterprise cloud security spending expands rapidly.
- The rebuffed acquisition mirrors a growing preference among premier Israeli cybersecurity founders to build durable public-market leaders rather than accepting early strategic exits.

Vintage's $920M close provides vital liquidity to founders and employees — relieving pressure on Israeli startups waiting out a sluggish public exit window.
BackgroundSecondary funds acquire existing shareholdings from venture capital firms, company founders, and early employees seeking cash distributions before formal initial public offerings or acquisitions. With corporate exits delayed across global tech markets, secondary capital serves as an essential liquidity valve.
- The $920M pool will be deployed across secondary share purchases and primary fund commitments throughout Israel, North America, and Western Europe, targeting mature venture-backed assets.
- Institutional allocations will provide early liquidity to venture-backed founders and technology employees while consolidating stakes in maturing tech winners at attractive secondary discounts.
- The closing underscores sustained foreign institutional appetite for experienced Israeli capital allocators despite macroeconomic volatility across the broader tech landscape.

Two Delta won tens of millions from Ackman and Schmidt for algorithmic chip efficiency — Israeli engineering is positioning to beat Silicon Valley's brute-force compute spending.
BackgroundEscalating hardware costs and semiconductor shortages have turned algorithmic compute optimization into a premier investment sector across global artificial intelligence. Israeli founders are leveraging mathematical and software engineering talent to extract higher throughput from constrained graphics processing clusters.
- Two Delta was established in 2025 by veteran technologists Dvir Zeltzer and Dr. Eli David to commercialize their DCOCO neural inference acceleration engine, promising orders-of-magnitude compute gains.
- The startup released EvoWeb, an evaluation framework benchmark measuring how autonomous software engineering agents navigate complex real-world web environments, establishing an open performance standard.
- Ackman announced his personal participation at Sheba Medical Center's innovation summit, arguing that focused Israeli engineering units routinely outmaneuver oversized Silicon Valley teams.
Startup
Mave turned military investigation workflows into autonomous enterprise agents — corporate security centers are shifting from human analyst shifts to automated software triage.
BackgroundModern enterprise security operations centers are overwhelmed by thousands of disparate security alerts generated across complex hybrid cloud infrastructure. Automating investigations with autonomous software agents allows corporate defense teams to neutralize threats without expanding human analyst shifts.
- Mave was founded by former IDF Unit 8200 officers Raziel Oren and Guy Eshel to automate investigation workflows across fragmented corporate networks, eliminating hours of manual triage.
- The startup reported securing seven-figure recurring contracts with Fortune 500 enterprises, driving a 400% revenue increase over the preceding six months and proving enterprise product-market fit.
- Proceeds will support doubling its 30-person engineering workforce in Tel Aviv while launching specialized sales hubs across North America to capture accelerating enterprise demand.
