Overview
C2i Semiconductors is a Bengaluru-based fabless semiconductor startup founded in June 2024 by former Texas Instruments executives including CEO Ram Anant. The company develops software-defined voltage regulator (VR) platforms for AI and HPC data centers — optimizing power delivery from the grid to the processor core. C2i claims its technology can exceed 96% conversion efficiency, reduce processor temperatures, and save millions annually at hyperscale. In 2026, the company extended its Series A to $16.7M with Peak XV Partners and TDK Ventures as lead investors. C2i announced tape-out of its smart power-stage chip for AI infrastructure in 2026.
Why C2i Semiconductors is interesting
C2i taped out its smart power-stage chip from India while Peak XV and TDK bet that grid-to-GPU power efficiency — not just more GPUs — is the bottleneck as AI data centers hit thermal and energy limits.
Product & use cases
Software-defined integrated vertical voltage regulator (V2R) platform delivering grid-to-core power management for AI accelerators and enterprise servers — targeting efficiency, heat reduction, and reliability in high-power AI racks.
- AI data-center rack power delivery optimization
- Hyperscale GPU cluster thermal and energy cost reduction
- Cloud infrastructure power-stage integration for next-gen AI accelerators
- India-origin semiconductor design for global OEM and data-center customers
Key facts
- $16.7M Series A total (Peak XV + TDK Ventures, 2026)
- Smart power-stage chip tape-out announced for AI infrastructure
- Founded June 2024 by ex-Texas Instruments semiconductor veterans
- Claims 96%+ power conversion efficiency vs ~90% incumbents (TDK release)
- Total funding ~$19M; building from Bengaluru with US expansion planned

Competitive landscape
Edge: Founding team of TI veterans with 100+ combined years and 100+ US patents in power management — building full power-stage silicon from India with strategic TDK alignment on passive-component co-development.
AI data-center power is shifting from afterthought to strategic chokepoint. C2i's early tape-out and Peak XV/TDK backing validate India's chip-design ecosystem — but fabless startups face long qualification cycles with hyperscalers and OEMs before revenue.

Notable stories
- Peak XV's Rajan Anandan told TechCrunch that after server and facility capex, energy becomes the dominant ongoing data-center expense — making incremental power efficiency highly valuable at AI scale.
- TDK Ventures highlighted strategic complementarity: TDK's passive components plus C2i's control topologies could co-develop next-gen vertical power modules neither could build alone.
