Bengaluru-based semiconductor startup Calligo Technologies has raised $1.1 million in a pre-Series A round, co-led by Seafund and Artha Venture Fund. The fresh infusion of capital will primarily be directed toward research and development, focused on building the Version 2.0 of its silicon chip and platform, alongside expanding its engineering team and technological capabilities, the company said in a press release.
Founded in 2012 by Anantha Kinnal, Rajaraman Subramanian, and Vinay N. Hebbali, Calligo Technologies develops cutting-edge solutions tailored for High-Performance Computing (HPC), Big Data, and AI workloads. The startup aims to tackle computational bottlenecks in large-scale modeling, simulations, and training/inference of large AI models—critical in scientific computing and modern enterprise AI systems.
Prior to this round, the company had raised $1.57 million from KITVEN and other early backers. With growing interest in AI and edge computing, the company’s timing couldn’t be more strategic.
Calligo has developed a novel platform that leverages modified RISC-V compilers and frameworks—including C/C++, gFortran, and Python—to support Posits, a number representation system considered more efficient than IEEE floating-point formats for AI/HPC applications. Notably, Calligo’s tech enables native Posit-enabled executables without requiring any source-level changes to existing applications, providing seamless integration into current HPC/AI environments.
In the past year, the company has built a custom accelerator board, achieved First Pass Silicon for Ver 1.0, and begun shipping to customers. It has also expanded internationally, collaborating with U.S. universities, national laboratories, and supercomputing centers, which has helped Calligo tap into global tech talent and prepare for a soft U.S. market launch.
India’s semiconductor sector is on a rapid growth trajectory, valued at $6.67 billion in 2024 and projected to reach $14.09 billion by 2032, growing at a CAGR of 10.1%. Calligo Technologies is well-positioned to ride this wave, with a product that aligns with both domestic innovation and global demand for high-efficiency computing solutions.
With its latest funding, Calligo is set to deepen its impact in the global semiconductor ecosystem, particularly in performance-critical AI and HPC applications.
