- Backslash Security
Participated · Series A · Feb 2026
Backslash Security is a Tel Aviv-based cybersecurity company focused on protecting AI-driven software development environments. Its platform plugs into modern IDEs and coding agents such as Cursor, Claude Code, Gemini Code Assist, and GitHub Copilot, giving security teams visibility, governance, and real-time protection over AI-assisted coding activities. The product also vets and monitors Model Context Protocol (MCP) servers to ensure AI-generated code complies with organizational security and regulatory requirements. By embedding security controls directly in the developer workflow, Backslash aims to let enterprises adopt AI coding tools without increasing risk exposure. The company plans to deepen the platform’s capabilities and expand its go-to-market reach in the United States and Europe.

- Materialspace
Led · Seed · Jan 2026
Materialspace builds a single, AI-driven software platform designed to replace the fragmented, spreadsheet-heavy workflows that dominate interior construction planning and procurement. The system ingests blueprints, product catalogs, and pricing data, then structures and optimizes that information so teams can move seamlessly from cost estimation through design and ordering. By unifying these steps, the company targets delays and inefficiencies that are exacerbated by skilled-labor shortages and increasing project complexity. Since launching its product less than a year ago, Materialspace reports rapid adoption and expansion, fueled mainly by distributors and manufacturers eager to scale without adding headcount or sacrificing margins. Co-founders and twin brothers Yoash and Nadav Palmor bring experience from manufacturing consulting and AI startups, respectively, to drive product development and market penetration. The firm positions its technology as a catalyst for fundamentally changing customer economics once critical workflows become continuous and intelligent. To support this vision, Materialspace has secured $7 million in Seed financing, its first publicly disclosed funding round.
- Quantum Art
Participated · Series A · Dec 2025
Quantum Art was spun out of Prof. Roee Ozeri's group at the Weizmann Institute of Science and is led by CEO and co-founder Dr. Tal David, CTO Dr. Amit Ben Kish and CSO Prof. Roee Ozeri. The company focuses on trapped-ion quantum computing and has developed proprietary techniques for multi-qubit gates, scalable modular architectures, and robust quantum error correction. It is advancing a multi-core roadmap including Perspective, a planned 1,000-qubit system aimed at commercial-scale deployment. Quantum Art is transitioning toward commercialization with plans for a Quantum-as-a-Service (QaaS) platform that lets customers move from algorithm development and co-design to execution on its hardware. The company said it is expanding internationally and building partnerships to support early customer adoption while hiring to support development and business growth.
- Eikona
Led · Seed · Dec 2025
Eikona offers a generative-AI engine that inserts an “adaptation layer” between marketers and their audiences, continuously modifying imagery, copy, video and layouts to maximize engagement and conversions. The system replaces traditional manual A/B testing by applying reinforcement learning from human feedback (RLHF), letting actual customer interactions determine which creative variants are served next. Eikona integrates directly into existing marketing-automation stacks and is already deployed by dozens of companies in retail, telecom, finance, healthcare, insurance and travel. Customers report double- and even triple-digit uplifts in sales, retention and click-through rates. Founded by CEO Nir Weingarten and CTO Omer Hacohen, the Israeli-American startup focuses on industries where customer loyalty is strategically critical. By automating creative iteration at scale, the platform promises to lower marketing budgets while boosting performance. The company positions itself as a production-grade alternative to prompt-based GenAI tools, ensuring brand, product and legal integrity are preserved while content continually evolves. No revenue or user numbers were disclosed, but the firm emphasizes measurable business impact for its early adopters.
