Semiconductor startup C2i Semiconductors has extended its Series A funding round to $16.7 million, with TDK Ventures participating in both the original raise and the oversubscribed extension.
The Bengaluru-based startup had secured $15 million in the first tranche of its Series A round led by Peak XV Partners, with participation from Yali Deeptech and TDK Ventures, in February this year. Prior to that, it had raised $4 million from deeptech venture fund Yali Capital in November 2024.
The fresh capital will be used to expand operations and accelerate product development efforts, C2i Semiconductors said in a press release.
Co-founded in June 2024 by Ram Anant, Vikram Gakhar, Preetam Tadeparthy, Dattatreya Suryanarayana, Harsha S B, and Muthusubramanian N V, C2i Semiconductors develops power management solutions for AI data centres and cloud infrastructure. The company focuses on system-level innovations aimed at rethinking how power flows from the grid to the processor core.
C2i’s differentiation lies in its proprietary intellectual property powering its products. Its platform includes the Manas Controller, a software-defined controller with a unique control architecture that is agnostic to PDN changes and processor requirements. The Sarayu Power Stage and Modular Scalability architecture enable flexible phase operations for higher-current applications, while also supporting VPD architecture and voltage regulators (VRs).
The startup recently announced the tape-out of its smart power stage chip designed for AI infrastructure. The chip was developed end-to-end in India by the company’s in-house semiconductor engineering team.
According to market research, AI infrastructure capex is expected to reach $500–600 billion over the next 12–18 months and could grow to $1 trillion by 2030.
C2i’s platform is projected to deliver over 96% power conversion efficiency, compared to the 94% efficiency offered by incumbent solutions. In a 100 MW AI data centre, these gains, combined with reduced heat generation, could translate into nearly $12 million in annual energy savings. Additionally, the technology enables processors to run up to 4°C cooler, potentially extending the lifespan of AI hardware.
