A packed Monday in Israeli high-tech: AI infrastructure company Decart closed a $300 million round at a roughly $4 billion valuation, adding Nvidia as a strategic investor; medical device giant Artivion completed its acquisition of Israeli Endospan for up to $335 million; and managed AI delivery platform Unframe announced a $50 million raise alongside crossing $100 million in total contract value within 12 months.

Funding Highlights

Decart raised a massive round led by Radical Ventures, with Nvidia joining as a new investor alongside eBay Ventures, Adobe Ventures, Toyota Ventures, Atreides Management, and Valor Equity Partners. Existing backers Sequoia Capital, Benchmark, and Zeev Ventures also participated. The round brings Decart's total funding to over $450 million since its 2023 founding. The company builds real-time generative AI infrastructure and world models, focusing on making it easier to switch between different AI chips — including those from Nvidia, Amazon, and Google. Amazon has also joined as a strategic customer.

Unframe completed a $50 million round led by Highland Europe, with participation from Bessemer Venture Partners, Craft Ventures, TLV Partners, Third Point Ventures, Cerca Partners, and Vintage Investment Partners. This is the company's third raise in 12 months, bringing total funding to $100 million. Founded in 2024 by CEO Shay Levi, COO Larissa Schneider, and Adi Azarya, Unframe operates a managed AI delivery platform that deploys tailored enterprise AI solutions in days — not weeks or months. Its numbers: over $100 million in total contract value in 12 months with 400% net revenue retention.

Tomorrow.io expanded its Series F by an additional $35 million, bringing the round to $210 million, with Pitango and its partner Harel Insurance joining alongside HarbourVest and Stonecourt. The funds accelerate the DeepSky AI-native weather satellite constellation. The company already operates 13 microwave sounder satellites with a global 60-minute revisit rate.

Exits and Acquisitions

Artivion (NYSE: AORT) completed its acquisition of Herzliya-based Endospan for a base price of $175 million (net payment of ~$135 million after loan offsets) with up to $200 million in contingent earnout based on U.S. commercial performance — a total potential value of $335 million. Endospan developed the NEXUS stent graft system for endovascular treatment of aortic arch disease. The acquisition was triggered by FDA PMA approval of the NEXUS system in April 2026.

In another deal, Ondas acquired Israeli military software firm Omnisys for $200 million. Omnisys develops AI-driven battlefield systems, expanding Ondas into defense-tech.

The Broader Picture

The Israel Innovation Authority opened its AI Strategy 2026 document for public consultation, with May 19 as the final submission date. The document outlines national AI policy directions.

Q1 2026 saw Israeli startups raise approximately $3.1 billion across 98 rounds — a 34% year-over-year increase — led by cybersecurity ($1.2 billion) and generative AI. The momentum continues into May: Israeli startups raised roughly $800 million in a single week recently, with AI and cybersecurity dominating.

Bottom Line

May 2026 continues to be a standout month for Israeli tech. Mega-rounds at Decart and Unframe, nine-figure exits at Endospan and Omnisys, and continued investment in space infrastructure at Tomorrow.io — all pointing to sustained global appetite for Israeli innovation, particularly in AI, cybersecurity, and space technologies.
