Code Metal Secures $125 Million Series B to Accelerate AI‑Driven Defense Software

Code Metal closed a $125 million Series B round, cementing its status as a unicorn Boston‑based AI startup that is reshaping defense software through advanced code‑translation technology.

Why the Funding Matters for AI‑Driven Defense Tech

In February 2026, the defense‑focused AI startup Code Metal announced a massive $125 million Series B financing led by Salesforce Ventures, with participation from Accel, B Capital, J2 Ventures and other strategic investors. The round values the privately held company at $1.25 billion, officially granting it unicorn status. This infusion of capital not only validates the market potential of AI code translation for national security but also accelerates the deployment of mission‑critical software across the defense ecosystem.

Key Takeaways

• Series B raised: $125 million
• Post‑money valuation: $1.25 billion
• Primary focus: AI‑powered code translation and verification for defense contractors and government agencies
• Early customers include L3Harris, RTX (formerly Raytheon) and the U.S. Air Force
• Strategic expansion into chip‑level portability and multi‑language support

Code Metal’s AI Code‑Translation Engine

At its core, Code Metal offers a proprietary AI platform that can translate high‑level programming languages—such as Python, Julia, MATLAB, and C++—into lower‑level or hardware‑specific languages like Rust, VHDL, and NVIDIA CUDA. The engine is built on large‑scale transformer models fine‑tuned on billions of lines of legacy and modern code, enabling it to understand both syntax and domain‑specific semantics.

The translation workflow follows a three‑step process:

1. Semantic Extraction: The AI parses the source code, building an abstract syntax tree (AST) enriched with type‑inference and data‑flow analysis.
2. Target Generation: Using a language‑agnostic representation, the model generates equivalent code in the target language, preserving performance characteristics and safety constraints.
3. Automated Verification: For each translation, Code Metal automatically creates test harnesses—virtual containers that execute unit, integration, and stress tests—to certify functional parity before delivery.

According to CEO Peter Morales, “If a translation cannot be verified with zero‑error confidence, the system simply reports that the conversion is not feasible.” This safety‑first approach is crucial for defense software, where a single bug can jeopardize mission outcomes or national security.

Who Backed the $125 Million Round?

The Series B was led by Salesforce Ventures, with existing backers Accel and B Capital returning to increase their stakes. New participants include J2 Ventures, a firm with deep ties to the defense sector, and several strategic corporate investors that see immediate value in integrating Code Metal’s technology into their own development pipelines.

The infusion pushes Code Metal’s valuation to $1.25 billion, granting it unicorn status—a rare achievement for a startup whose primary market is defense software. The capital will be allocated to three strategic pillars:

• R&D Expansion: Scaling the AI model family to support additional legacy languages (e.g., Fortran, Ada) and emerging hardware architectures.
• Global Sales Footprint: Opening regional hubs in Europe and Asia to serve defense ministries and prime contractors.
• Compliance & Security: Investing in FedRAMP, ITAR, and NIST certifications to meet stringent government procurement standards.

Implications for Defense Software and National Security

Legacy codebases are a persistent challenge for defense agencies. Many critical systems—ranging from radar signal processing to satellite telemetry—still run on languages that are decades old. Modernizing these systems without introducing vulnerabilities is a high‑stakes problem.

Code Metal’s AI translation engine addresses three core pain points:

1. Speed to Market: Engineers can convert legacy modules into modern, maintainable code in weeks rather than months, accelerating the deployment of upgrades and patches.
2. Talent Flexibility: By abstracting away language‑specific expertise, organizations can reassign senior engineers to higher‑value tasks while junior staff handle the translated code under automated verification.
3. Risk Mitigation: The built‑in test harnesses provide a quantifiable confidence level, reducing the likelihood of hidden bugs that could compromise mission‑critical operations.

Analysts from the defense‑tech hub note that AI‑driven code translation could become a “strategic enabler” for next‑generation autonomous systems, where software updates must be delivered securely and rapidly across heterogeneous hardware platforms.

Founder’s Vision and the Road Ahead

“The defense industry is at a crossroads where legacy code is both a liability and a treasure trove of proven algorithms. Our mission is to unlock that value safely, so the nation can field the most advanced systems without reinventing the wheel.” – Peter Morales, CEO of Code Metal

Morales, a former Microsoft engineer and MIT Lincoln Laboratory researcher, emphasizes that the next phase will focus on “AI‑augmented verification,” where the system not only tests translated code but also suggests optimizations for performance and security.

He also highlighted upcoming partnerships with major chip manufacturers to enable “cross‑architecture portability,” allowing a single codebase to be compiled for CPUs, GPUs, and specialized ASICs with a single click.

How This Funding Shapes the AI Landscape

The Series B round signals a broader market shift: investors are increasingly betting on AI tools that act as “picks and shovels” for the defense sector, rather than on end‑user applications alone. By providing a foundational capability—reliable, verifiable code translation—Code Metal positions itself as a critical infrastructure provider for the next wave of AI‑enabled defense platforms.

For technology enthusiasts and venture capitalists, the deal underscores two trends:

• AI as a Compliance Layer: Automated verification aligns with emerging regulatory demands for software assurance in high‑risk domains.
• Unicorns in Niche Markets: Even highly specialized B2B AI startups can achieve billion‑dollar valuations when they solve mission‑critical problems.
