CalligoTech Raises $1.1 Mn In Pre-Series A Round

Calligo Technologies, a semiconductor startup has raised $1.1 million (around INR 9.4 Cr) in a Pre-Series A funding round led by Seafund and Artha Venture Fund.

The funds will be used to develop version 2.0 of Calligo's silicon chip and platform, invest in research and development and grow its engineering and tech teams.

CalligoTech also plans to build more advanced semiconductor products and form partnerships with system integrators and OEMs/ODMs.

"Insatiable demand for computing for HPC/AI has thus far been addressed by adding more and more Hardware, without addressing computing efficiency at grass-root levels. POSIT is a game-changing invention for real-number representation, as it tackles this issue by enabling the use of fewer computing bits for the same or improved mathematical accuracy, higher energy efficiency, and an increase in dynamic range," said Anantha Kinnal, cofounder and Managing Director of Calligo Technologies.

"Combining Posits with RISC-V, our current version of Silicon TUNGA - an Octacore RISC-V CPU - powers our accelerator card that can be added to any X86/ARM/PowerPC-based Servers. This is already enabling researchers worldwide to realize the usefulness of  Posit-based computing," Kinnal added.

"Compute requirement is growing exponentially across the globe. CalligoTech chips and platform improves performance and reduces data power consumption with their innovative approach. They have completed the full chip cycle from design to products in v1.0 and are accelerating to tapeout the nextgen silicon," said Narendra Bhandari, General Partner, Seafund.

"With AI and HPC workloads growing exponentially, computing efficiency is more critical than ever. Calligo’s POSIT-based chips solve fundamental performance bottlenecks, enabling faster, more precise, and power-efficient computing at scale. As demand for large-scale modeling and AI training surges, we see POSIT as a game-changing innovation poised to become a new standard in computing," said Anirudh A Damani, Managing Partner of Artha Venture Fund.

About Calligo Technologies

Founded in 2012 by Anantha Kinnal, Rajaraman Subramanian and Vinay N. Hebbali, Calligo Technologies builds solutions for high-performance computing (HPC), big data, and AI. Its goal is to fix performance issues in large-scale simulations and AI model training.

It has also updated RISC-V compilers and tools to support Posits—a new number format—so that HPC and AI applications can run without changing the original code.
