Protego Ventures secures $125 million to scale battlefield-proven Israeli defense tech, targeting AI, autonomous systems, and global security infrastructure.

The intersection of venture capital and national security has evolved from a niche curiosity into a primary driver of technological innovation. This shift is exemplified by the recent final close of the debut fund from Protego Ventures, which has secured $125 million in capital commitments. Positioned as the first and largest venture capital firm in Israel dedicated exclusively to defense technology, Protego enters a market where defense-tech dealmaking reached record highs in the first quarter of 2026.

A strategic pivot toward battlefield-proven tech

Unlike traditional seed-stage funds that bet on theoretical breakthroughs, Protego Ventures focuses on early-growth companies. The firm specifically targets startups that have already transitioned from the lab to the field, prioritizing technologies that have been validated in operational or battlefield environments. This approach reduces the typical risk associated with deep-tech investments by ensuring that the product-market fit is not just theoretical but has been tested under the most extreme conditions imaginable.

The fund's investment range is flexible, deploying between $5 million and $50 million per company. By focusing on this growth stage, Protego aims to bridge the gap between initial development and global scaling, providing the capital necessary for startups to expand their manufacturing and operational footprints.

The XTEND effect and the logic of fund sizing

One of the most striking aspects of Protego's fundraising strategy was the decision to stop short of its initial $150 million target. The firm closed at $125 million for a specific financial reason: the explosive success of its first portfolio company, XTEND. The drone manufacturer recently went public on the New York Stock Exchange, creating a scenario where a single investment could potentially return the entire value of the fund.

Lital Leshem, co-founder of the firm, noted that raising additional capital at this stage would have diluted the upside for existing investors. In the venture capital world, a 'fund maker' is a rare asset that guarantees a high internal rate of return. By capping the fund size, Protego ensures that the gains from XTEND's public debut have a magnified impact on the overall fund performance, avoiding the need to 'share the pie' with a larger pool of late-coming limited partners.

Core technological pillars and portfolio reach

Protego's investment thesis centers on critical security needs that transcend national borders. The firm is not merely investing in hardware but in the intelligence layers that make hardware effective. Their portfolio spans several high-stakes domains:

Autonomous systems and AI are central to their strategy, focusing on reducing human risk in contested environments. They also prioritize critical infrastructure sensing and navigation systems designed to operate in environments where traditional communications and GPS signals are disrupted or jammed—a growing necessity in modern electronic warfare.

Beyond XTEND, the portfolio includes ASIO, a company specializing in situational awareness systems. ASIO's strategic importance is further highlighted by its partnership with Anduril, one of the most prominent defense-tech unicorns in the United States. This connection underscores Protego's role as a bridge between Israeli innovation and the American defense industrial base.

Origins born from necessity

The genesis of Protego Ventures is deeply tied to the geopolitical shocks of recent years. The firm was conceptualized in the aftermath of the October 7, 2023, Hamas attacks. It was Ares Management, one of Protego's largest backers with a $30 million commitment, that suggested Lital Leshem and Lee Moser join forces to create the fund. The conviction was clear: new, agile technologies were essential to bolster defense capabilities against evolving threats.

The leadership team brings a blend of operational and financial expertise. Leshem spent 11 years within the IDF and the intelligence community and co-founded Carbyne, while Moser provides seasoned venture capital experience. This combination allows the firm to navigate the opaque and highly regulated world of defense procurement while maintaining the discipline of a professional investment house.

Scaling Israeli innovation for global markets

While the fund is rooted in Israel, its ambitions are global. Protego does not view itself as a local investor but as an accelerator for international expansion. The firm actively connects its portfolio companies with global business partners, international investors, and defense customers. This is a critical service, as the transition from a domestic military contract to a global export deal often requires navigating complex regulatory frameworks and establishing trust with foreign ministries of defense.

According to Leshem, the reception within military circles has been overwhelmingly positive. The firm has become a point of contact for entities seeking to learn about and integrate cutting-edge innovation, often operating 'under the radar' to acquire technological advantages in a competitive global landscape.

Global implications for US and UK enterprises

For entrepreneurs and investors in the USA and UK, the rise of dedicated funds like Protego signals a permanent shift in how defense technology is funded. We are moving away from the 'cost-plus' contracting model of legacy defense primes toward a venture-backed model that prioritizes speed and iterative development.

In the United States, this aligns with the growing trend of the Department of Defense utilizing vehicles like the DIU (Defense Innovation Unit) to integrate commercial tech faster. For UK firms, it mirrors the push toward the 'Integrated Review' goals of enhancing technological edges in AI and autonomous systems. The success of Protego suggests that 'battlefield-proven' is becoming the gold standard for valuation in the defense sector.

Companies in the West looking to partner with Israeli startups should note that these entities are now better capitalized and more strategically aligned with global markets. The presence of US-based LPs like Ares Management in these funds creates a streamlined pipeline for technology transfer between the Israeli ecosystem and the US defense market, potentially lowering the barriers to entry for dual-use technologies.
