Israeli startups raise over $1.25 billion in April, lifted by Vast Data’s mega-round
Despite just nine funding rounds amid Passover and Independence Day, a single $1 billion raise by Vast Data propelled April to its strongest showing since 2021.
April is not typically a defining month for venture capital activity in Israel, and this year followed that seasonal pattern, at least on the surface. The calendar was fractured by Passover and Independence Day, compressing dealmaking into fewer working days and contributing to a modest tally of just nine funding rounds.
Yet the headline number tells a different story.
Israeli startups raised more than $1.25 billion in April, making it the strongest April for funding since 2021. The figure was driven overwhelmingly by one transaction: Vast Data’s $1 billion raise at a $30 billion valuation.
Cybersecurity and AI agent management also featured prominently. Capsule Security raised $7 million to secure enterprise AI agents, focusing on real-time control of autonomous systems, while Copperhelm brought in $7 million to automate cloud security using AI agents. Band, founded by veterans of Sygnia and Ermetic, raised $17 million in seed funding to build what it describes as a “WhatsApp for AI agents,” addressing the growing challenge of coordination between autonomous systems and enterprises.
Even consumer-facing sectors reflected the AI-driven shift in market dynamics. Haat, a food delivery startup, raised $20 million at a $100 million valuation as it moves into Tel Aviv to challenge established players, leveraging scale built in underserved regions.
April also highlighted renewed momentum in quantum computing, with two separate funding announcements pointing to growing investor interest in the field.
Quantum Art extended its Series A to $140 million, adding $40 million as it advances toward a 1,000-qubit system and commercial-scale deployment. Meanwhile, Q-Factor, a stealth startup backed by Intel Capital and founded by scientists from the Weizmann Institute and Technion, emerged with $24 million in seed funding, aiming to move beyond current qubit limitations using neutral atom technology.
Aidoc raised $150 million to advance AI in clinical decision-making, backed by a foundation model aimed at transforming radiology workflows and reducing diagnostic errors. In enterprise infrastructure, Definity secured $12 million in a Series A round to automate data pipelines, targeting inefficiencies that emerge as companies scale AI operations.
