Calligotech

Calligotech is a semiconductor and computing technology company developing next-generation computing solutions for high-performance computing (HPC) and AI workloads. The company has developed a novel computing architecture based on POSITs (posit numbers), a alternative to floating-point arithmetic that delivers higher precision and wider dynamic range with fewer bits, enabling more efficient computation for AI and HPC applications. Calligotech’s product portfolio includes TUNGA and UTTUNGA, which serve as hardware accelerators designed to improve performance and energy efficiency for demanding computational workloads. The technology targets industries including life sciences, oil and gas, automotive, aerospace, smart cities, industrial IoT, and weather and climate modeling. By leveraging POSIT-based processing, Calligotech aims to overcome the limitations of traditional floating-point hardware, offering improved accuracy, reduced memory bandwidth requirements, and faster execution for AI training and inference as well as scientific simulations. The company provides both products and warranty services. Founded in 2012 and headquartered in Bengaluru, India, the company has raised approximately $2.7 million in Seed funding. Investors include Quest Smartech, KITVEN, UST, SFAL, Seafund, and Artha Venture Fund.
