Operational validation accelerates the path to scalable deployment

PlusAI, a leader in AI-based virtual driver software for autonomous trucks, today announced it has achieved four internationally recognized ISO certifications, marking a definitive milestone in its transition to a market-ready autonomous powerhouse. This "quadruple" certification in quality (ISO 9001), cybersecurity (ISO/SAE 21434), functional safety (ISO 26262), and data security (ISO 27001) formally validates PlusAI’s operational maturity. This achievement, paired with the company's recent 90.1% Safety Case Readiness (SCR) milestone, establishes a clear, de-risked path for the targeted 2027 launch of factory-built autonomous trucks with global OEM partners.

PlusAI Secures Four Key ISO Certifications Ahead of Commercial Launch of SuperDrive™-Integrated Factory-Built Autonomous Trucks

“Achieving these four ISO certifications is pivotal for PlusAI,” said David Liu, CEO and Co-Founder of PlusAI. “It formally validates that our safety, cybersecurity, information security and quality processes meet the global standards required by our OEM partners. These certifications provide third-party validation that our SuperDrive™ platform is ready to scale globally with the world’s leading truck manufacturers.”

A Comprehensive Moat: The Four Pillars of Commercial Readiness

The ISO certifications place PlusAI among the most rigorously validated companies in the autonomous trucking sector:

• ISO 9001:2015 (Quality Management): Validates industrial-grade processes designed for consistency and meets the baseline quality expectations of global OEMs.
• ISO/SAE 21434 (Road Vehicle Cybersecurity): Establishes a structured, end-to-end framework to protect autonomous fleets against digital threats and meets emerging global regulatory requirements.
• ISO 26262 (Functional Safety): Governs the fundamental safety of road-going motor vehicles; essential for the removal of the safety driver in Level 4 operations.
• ISO 27001 (Information Security): Ensures that the massive data sets powering PlusAI’s "Reasoning-Reflex" AI-native stack are managed with enterprise-grade auditable controls.

Path to 2027 Commercial Launch

The certifications strengthen PlusAI’s position as the autonomy partner for TRATON GROUP (Scania, MAN, International brands), Iveco Group, and Hyundai. These automotive-grade benchmarks demonstrate PlusAI’s readiness for factory level integration of SuperDrive™.

PlusAI is currently on track to commercially launch factory-built autonomous trucks in the Texas Triangle in 2027, followed by expansion into major freight corridors in the Sunbelt states and Europe.

A Record of Global Commercial Leadership

These certifications come as PlusAI continues to expand its partnerships with global truck manufacturers and logistics leaders:

• Expanded Partnership with TRATON GROUP: Under an expanded agreement that is currently subject to a non-binding term sheet, TRATON would commit up to $25 million in non-dilutive R&D funding to PlusAI to accelerate factory integration of SuperDrive™ into autonomous trucks of TRATON’s brands. In connection with PlusAI’s planned public listing, TRATON will nominate a representative to the initial PlusAI Board of Directors to further align the organizations as they prepare for a planned U.S. commercial launch. TRATON will also be eligible to receive private warrants tied to initial deployment revenue milestones based on revenue earned by PlusAI from commercial deployments of TRATON-branded trucks equipped with SuperDrive™.
  
  
  
  
• First Level 4 Program in Southern Europe with IVECO and Sesé: PlusAI recently announced the first L4 autonomous trucking program in southern Europe with IVECO and Spanish logistics leader Sesé. This multi-year initiative on the Madrid-Zaragoza corridor marks a critical step in European autonomous freight adoption.
  
  
  
  
• Strategic Entry into Japan with Mitsui and T2: Backed by an investment from Mitsui & Co., Ltd., PlusAI has partnered with T2 to bring Level 4 autonomous trucking to Japan. This collaboration combines PlusAI’s global deployment experience with T2’s local logistics expertise to address Japan’s critical driver shortage.
