Bengaluru-based Calligo Technologies has raised USD 1.1 million (~INR 9.48 crore) in a pre-Series A funding round led by Seafund and Artha Venture Fund to further its mission to transform the high-performance computing (HPC) and AI landscape with its next-gen silicon chip technology.
This is a big milestone for CalligoTech, enabling the company to accelerate R&D on its second-gen POSIT-enabled RISC-V, System-on-Chip (SoC), expand its engineering team and solidify partnerships with OEMs, ODMs and system integrators globally.
Calligo Technologies
Founded in 2012 by Anantha Kinnal, Rajaraman Subramanian and Vinay N. Hebbali, Calligo Technologies is building semiconductor and software solutions to power the next era of HPC, Big Data and AI/ML workloads. Their core innovation is based on POSIT, a new real-number representation system that enhances computing accuracy, dynamic range and energy efficiency by reducing the bit count for computation.
“Compute demand for HPC and AI has so far been met by adding more hardware. CalligoTech addresses this from the roots—redefining computational efficiency itself,” said Anantha Kinnal, Co-founder and CEO, Calliga Technologies.
Their first-gen chip (ver1.0) has completed the full silicon cycle, with working units already shipped to customers and research institutions. These chips power TUNGA, CalligoTech’s proprietary accelerator card based on an Octacore RISC-V CPU that can plug-and-play with existing X86, ARM and PowerPC servers.
Use of Funds
With this new funding, CalligoTech is now focused on taping out its second-gen 64-core POSIT-enabled RISC-V SoC within the next 12-18 months. The SoC will take computing to the next level. It will be more precise and power-efficient at scale, as data-intensive workloads from AI, simulation and big data continue to grow exponentially. “Not just another chip, they’re redefining compute itself,” said Anirudh A Damani, Artha Venture Fund.
Market-Ready Ecosystem
To ensure smooth integration and adoption, CalligoTech has invested in compiler and language support, modifying popular programming ecosystems like C/C++, gFortran, and Python to generate POSIT-enabled executables. This means enterprises and research teams can adopt Calligo’s platform without changing their source code—a big win in reducing migration complexity.
“CalligoTech is already showing early traction in research labs with their TUNGA accelerator board. Their next-gen chip will allow large customers to benchmark performance, efficiency and scalability,” said Narendra Bhandari, General Partner at Seafund.
Timing is Everything in India’s Semiconductor Boom
This funding round coincides with the broader momentum in India’s semiconductor ecosystem, which was valued at USD 6.67 billion in 2024 and is expected to reach USD 14 billion by 2032, according to Custom Market Insights. Initiatives like India Semiconductor Mission 2.0 (ISM 2.0) and the Semicon India Programme—with an outlay of INR 76,000 crore—underline the national plan to make India a global hub for electronics design and manufacturing.
CalligoTech’s emergence as a deep-tech company solving real computing inefficiencies fits into this macro narrative. With its focus on hardware-software co-design, open standards like RISC-V, and energy-conscious architectures, they are well-positioned to play a big role in India’s silicon value chain and beyond.
What’s Next
CalligoTech’s roadmap for the next 18 months:
- Release ver2.0 POSIT-enabled SoC
- High-volume manufacturing partnerships
- Global deployments
- Engineering and research team growth
- U.S. and European market expansion
In a world of efficiency, scalability and sustainability, Calligo Technologies is not just building chips—it’s engineering the future of precision and performance computing.
