C2i Semiconductors Extends Series A Funding to $16.7M with TDK Ventures

Why It Matters

The infusion accelerates C2i’s go‑to‑market timeline, allowing it to capture a slice of the booming AI data‑centre market where power efficiency is a critical cost driver.

Key Takeaways

• Series A extended to $16.7 million, TDK Ventures repeats participation.
• Platform targets AI data centre power efficiency, 96% conversion rate.
• Potential $12 million yearly energy savings for 100 MW facilities.
• Tape‑out of smart power‑stage chip completed in India.

Pulse Analysis

The AI boom is reshaping data‑centre economics, with operators projected to invest $500‑600 billion in infrastructure over the next year and a half. Power consumption accounts for a sizable portion of total operating costs, prompting a race for solutions that can squeeze every watt of efficiency. In this environment, C2i Semiconductors’ focus on system‑level power management aligns with a clear market need: higher conversion efficiency translates directly into lower electricity bills and reduced cooling requirements, both of which are paramount for hyperscale operators.

C2i’s differentiated portfolio centers on its Manas Controller, a software‑defined architecture that adapts to changing power‑delivery network (PDN) conditions without hardware redesign. Coupled with the Sarayu Power Stage and a modular scalability framework, the platform can handle high‑current loads while supporting voltage‑regulator‑as‑a‑service (VPD) models. The claimed 96% conversion efficiency—two points above incumbent solutions—means a 100 MW AI data centre could shave roughly $12 million in annual energy costs and keep processors up to 4 °C cooler, extending hardware lifespan and reducing maintenance cycles.

The $16.7 million Series A extension, led by Peak XV Partners and reinforced by TDK Ventures, underscores growing investor confidence in India’s deep‑tech semiconductor ecosystem. With a successful tape‑out of its smart power‑stage chip and a pipeline of AI‑focused power solutions, C2i is positioned to challenge established players and capture market share as AI workloads proliferate. Continued capital support will be critical for scaling manufacturing, expanding the engineering team, and securing early‑stage customers in a market where efficiency gains are quickly monetized.

Deal Summary

Semiconductor startup C2i Semiconductors announced an extension of its Series A round, raising the total to $16.7 million. The oversubscribed extension includes participation from TDK Ventures, adding to the $15 million raised earlier in February. The new capital will fund expansion of operations and accelerate product development for AI data-center power-management solutions.
