C2i Semiconductors raised $16.7 million in its Series A funding round, led by Peak XV Partners, with participation from TDK Ventures and Yali Capital.
The round was an extension of an earlier $15 million raise in February 2026, bringing the total to $16.7 million.
The startup plans to use the funds to expand operations and accelerate product development in the AI infrastructure and cloud computing market.
C2i recently announced the tape-out of its smart power stage chip designed for AI infrastructure, developed entirely in India by its in-house engineering team.
The chip is part of C2i’s platform, which includes the Manas Controller and Sarayu Power Stage, aiming to deliver over 96% power conversion efficiency.

The demand for AI infrastructure is growing rapidly, with global AI infrastructure capital expenditure projected to reach between $500 billion and $600 billion in the next 12 to 18 months.
Modern AI chips are becoming more power-hungry, with future processors expected to demand up to 4,500W of power.
C2i’s technology addresses the 'last-inch' power challenge, improving efficiency and reducing heat generation in data centres.
The startup’s platform is built around proprietary intellectual property, including a software-defined controller and modular scalability architecture.

C2i Semiconductors develops power management solutions for AI data centres and cloud infrastructure.
The company focuses on system-level innovations that rethink how power is delivered from the grid to processor cores.
Its platform includes the Manas Controller, a software-defined controller with a unique control architecture, and the Sarayu Power Stage, designed for flexible phase operations.
C2i’s technology claims to deliver more than 96% power conversion efficiency, compared to around 94% in existing solutions.
The startup estimates that its improvements could help generate nearly $12 million in annual energy savings in large-scale AI data centres.

C2i plans to use the fresh capital to expand operations and accelerate product development in the AI infrastructure and cloud computing market.
