C2i Semiconductors Extends Series A Funding to $16.7 Million

Bengaluru-based deeptech startup C2i Semiconductors has extended its Series A funding round to a total of $16.7 million, supported by an oversubscribed extension featuring participation from TDK Ventures [1]. This latest injection of capital builds upon a $15 million initial tranche raised in February 2024, which was led by Peak XV Partners with additional backing from Yali Deeptech and TDK Ventures [2].

Key takeaways

• The company has secured a total of $16.7 million in Series A funding to scale operations and accelerate product development [1, 4].
• C2i Semiconductors was founded in June 2024 by a team of six engineering professionals, including Ram Anant and Vikram Gakhar [1, 4].
• The startup claims its proprietary platform can achieve over 96% power conversion efficiency, potentially reducing energy costs in large-scale data centers [1, 2].
• The company recently announced the tape-out of a smart power stage chip designed in-house in India for AI infrastructure [1, 2].

Innovations in AI Power Delivery

C2i Semiconductors focuses on system-level power management solutions designed to optimize how electricity is delivered from the grid to processor cores in AI data centers and cloud infrastructure [1, 3]. The company’s technology stack includes the Manas Controller, a software-defined system that remains adaptable to varying processor requirements and power delivery networks [1, 2]. Additionally, the firm utilizes its Sarayu Power Stage and a modular scalability architecture to support high-current applications and voltage regulators [1, 2].

The startup asserts that its platform offers significant performance improvements over existing market solutions, which typically provide 94% power conversion efficiency [1, 2]. By reaching efficiencies exceeding 96%, C2i estimates that a 100 MW data center could realize nearly $12 million in annual energy savings while allowing processors to operate up to 4°C cooler [1]. These advancements are intended to lower heat generation and potentially extend the lifespan of AI hardware systems [1, 2].

Why it matters

As global demand for AI infrastructure intensifies, market estimates suggest that capital expenditure in the sector could reach between $500 billion and $600 billion over the next 12 to 18 months, with projections climbing toward $1 trillion by 2030 [1]. C2i’s focus on energy optimization addresses a critical bottleneck for data centers struggling to manage the power requirements of high-performance processors [3].

The company plans to use the fresh capital to expand its operations, build engineering capabilities, and scale global partnerships [3, 4]. While the firm faces the challenge of operating in a market heavily dependent on imported semiconductors, its efforts align with broader industry trends toward homegrown semiconductor design and specialized power management solutions within India [3].
