Yours faithfully, For Tata Elxsi Limited Sneha V Company Secretary & Compliance Officer Encl.: As above Tata Elxsi Invests in KAVIA AI to Scale AI-Driven Software Engineering for Products and Enterprises Bengaluru, India, September 10, 2026 – Tata Elxsi, a global leader in design and technology services, today announced a strategic investment in KAVIA AI, a Silicon Valley-based enterprise AI platform company. The investment strengthens the collaboration between the two companies to help enterprises manage, modernise, and transform complex software environments at scale. As a global leader in AI and GenAI-driven product and software engineering, Tata Elxsi enables enterprises to implement the AI Development Lifecycle (AIDLC), accelerating architecture design, brownfield refactoring, software development, quality assurance, deployment, continuous monitoring and debugging across the product and software lifecycle. The collaboration brings together Tata Elxsi's expertise in domain-led engineering with KAVIA AI's knowledge graph and workflow intelligence platform. Over the past one year, the companies have worked together to deploy the platform for enterprise engineering use cases, addressing challenges around industry-specific product and software engineering, accelerated release cycles, quality, resilience, and cybersecurity readiness. Manoj Raghavan, Chief Executive Officer and Managing Director, Tata Elxsi, said, “Through STEP.UP, Tata Elxsi's startup engagement program for high-potential deep tech companies, we have worked closely with KAVIA AI and seen the strength of its technology firsthand. This investment reflects our shared vision for AI-driven software engineering.” Across industries, distributed teams have been creating millions of lines of code over the years using multiple repositories and diverse technology stacks to evolve enterprise products and platforms. As organisations face this complex brownfield environment, critical knowledge often remains fragmented across code, documentation, systems, tools, and teams. While most AI tools focus on accelerating coding, KAVIA AI enables enterprises to scale across the AIDLC by combining persistent knowledge, governed engineering artifacts, collaboration, traceability, and deployment through a single platform. Labeeb Ismail, Founder and Chief Executive Officer, KAVIA AI, said, “We are delighted with this strategic investment by Tata Elxsi and the trust it has placed in us. KAVIA AI brings system assets for enterprises to establish AIDLC workflows, operating models, and the checks and balances needed to operationalise AI across the software lifecycle. Together with Tata Elxsi, we look forward to shaping the future of software delivery.” Building on this foundation, Tata Elxsi and KAVIA AI are working together to harness the power of AI responsibly and help organisations transform their products and services.
