C2i Semiconductors Extends Series A Round to USD 16.7 Mn

Semiconductor startup C2i Semiconductors has extended its Series A funding round to USD 16.7 million, adding fresh capital through an oversubscribed extension that saw participation from TDK Ventures.

The Bengaluru-based company had earlier raised USD 15 million in the first tranche of its Series A round in February this year. The round was led by Peak XV Partners, with participation from Yali Deeptech and TDK Ventures. Prior to this, the startup secured USD 4 million from Yali Capital in November 2024.

The newly raised funds will be used to expand its operations and accelerate product development efforts.

Founded in June 2024 by Ram Anant, Vikram Gakhar, Preetam Tadeparthy, Dattatreya Suryanarayana, Harsha S B, and Muthusubramanian N V, C2i Semiconductors focuses on developing power management solutions for AI data centres and cloud infrastructure. Its approach centres on system-level innovations that aim to improve how power is delivered from the grid to processor cores.

The company’s platform is built on proprietary intellectual property and includes products such as the Manas Controller, a software-defined system designed to function across varying processor and power delivery network requirements. Other components, including the Sarayu Power Stage and its modular scalability architecture, are intended to support higher-current applications and flexible operations.

C2i recently announced the tape-out of its smart power stage chip for AI infrastructure, which was developed entirely in India by its in-house engineering team.

The startup claims its platform can achieve over 96% power conversion efficiency, compared to around 94% offered by existing solutions. It also estimates that improved efficiency and reduced heat output could lower energy costs and enhance hardware longevity in large-scale AI data centres.
