CodeMetal.ai provides a SaaS platform that turns research code into optimized, edge-ready low-level code. It serves academia, defense, and tech sectors in AI and machine learning. Users upload code written in Python, Julia, or MATLAB, pick target deployment chipsets, and the platform automatically optimizes the code and adapts it to chosen runtimes, iteratively improving performance. This approach differentiates CodeMetal.ai by offering multi-language support, chipset-aware optimization, and runtime adaptation within a cloud-based service, enabling users to deploy efficient code on edge devices without manual low-level tuning. The company's goal is to help clients run more efficient AI/ML workloads on edge hardware by converting high-level research code into fast, platform-optimized implementations via subscriptions and usage-based pricing.

Our investment in Code Metal.
Code Metal secures $125M Series B at $1.25B valuation to bridge the trust gap in AI code generation. New funding, the appointment of President and COO Ryan Aytay, and rapidly expanding contracts position Code Metal as one of the fastest-growing software defense technology companies BOSTON-(BUSINESS WIRE)-Code Metal, the leader in verifiable code translation for mission-critical industries, today announced the close of its $125 million Series B financing led by Salesforce Ventures with participation from Accel, B Capital, Smith Point Capital, J2 Ventures, Shield Capital, Overmatch, RTX, and others. The company also announced that Ryan Aytay, former CEO of Tableau, has joined Code Metal as President and Chief Operating Officer. This new round comes just months after Code Metal's Series A, underscoring the company's rapid growth and the urgency with which defense and other regulated industries are moving to adopt verifiable AI capabilities. With its technology already deployed across defense, automotive, semiconductor, and other mission-critical industries, Code Metal is among the fastest-growing defense technology companies, as measured by revenue growth, contract scale, and the pace of adoption among top-tier government and enterprise customers. The funding will be used to add engineering capacity, accelerate product development, expand commercial and government partnerships, and scale Code Metal's go-to-market capabilities. Customers, including Toshiba, RTX, L3Harris, and the U.S. Air Force, use Code Metal to move between programming languages and optimize software for hardware at unprecedented speed. Today, generating code with AI alone is not sufficient for mission-critical industries where compliance, safety, accuracy, and performance are a priority. Code Metal's unique approach enables customers to translate and optimize code for any environment while also ensuring the code is verified, validated, and production-ready. "AI code generation has hit an inflection point: mission-critical industries cannot deploy what they cannot verify," said Rob Keith, Partner at Salesforce Ventures. "Code Metal's neuro-symbolic approach solves this by mathematically proving code is correct. The unprecedented adoption velocity drove our decision to lead the round; in just one year, demand has pulled Code Metal into programs of record across the U.S. Air Force, L3Harris, and more. Salesforce Ventures brings deep experience scaling enterprise platforms, and we are proud to back the team building the load-bearing infrastructure for this ecosystem." "This new funding round marks an important milestone for Code Metal and validates our mission to close the trust gap in AI-generated code," said Peter Morales, founder and CEO of Code Metal. "AI can generate code at unprecedented speed, but in mission-critical environments, speed without proof is not enough; we are building the infrastructure that ensures software can be trusted before deployment, and with Salesforce Ventures' partnership and Ryan's firsthand expertise with these customers, we are scaling with the operational excellence this market demands." Aytay brings decades of experience building and scaling enterprise technology businesses. He served as CEO of Tableau and spent many years at Salesforce in senior leadership roles, helping to grow and operate one of the world's most successful enterprise software companies. In his new role, Aytay will focus on scaling Code Metal's operations, commercial execution, and partnerships in close collaboration with Morales and the leadership team, with a particular emphasis on deepening relationships across defense, automotive, and other mission-critical industries. "I'm excited to join Code Metal at such an important moment for the company and for the industry," said Ryan Aytay, President and COO of Code Metal. "AI is changing how code is built, but in mission-critical environments, the standard has to be higher than simply generating code. Code Metal is the leader in trusted verification and validation of AI-generated and legacy code, and its adoption among some of the most critical industries worldwide shows that this approach is already reshaping the software defense landscape. I'm looking forward to partnering with Peter and the team to scale the business." "AI has transformed how software is written, but code portability and translation remain challenging," said Yan-David Erlich, General Partner at B Capital. "We've been impressed by Code Metal's strong traction, particularly in helping defense customers develop and deploy on edge devices in safety-critical settings, and we're excited to back this excellent team as they scale." ABOUT CODE METAL Code Metal provides verifiable code translation and optimization of AI-driven and legacy code across any development environment. As compute shifts toward specialized hardware and edge environments, Code Metal's approach enables teams to improve portability and performance while maintaining the correctness required for production-ready deployment. Additional details about Code Metal and its platform are available at codemetal.ai.
Code Metal, a Boston-based startup using AI to write and translate code across programming languages, has raised $125 million in Series B funding. The round follows a $36 million Series A led by Accel just months earlier. Founded in 2023, Code Metal focuses on code translation and verification for the defence industry, with early customers including L3Harris, RTX and the US Air Force. The company also works with Toshiba and is in discussions with a major chip manufacturer. The platform translates code from high-level languages like Python and C++ to lower-level languages such as Rust and Nvidia's CUDA. CEO Peter Morales, formerly of Microsoft and MIT Lincoln Laboratory, says the technology addresses the challenge of porting legacy code into new applications, particularly when agencies lack engineers specialised in modern programming languages.
