Tattvam AI

Tattvam AI is a London-based deep-tech company building AI systems that automate the design of semiconductor chips. Founded in 2025, the company targets one of the most technically demanding problems in modern engineering: physical design, the stage at which a chip's logical architecture is converted into a manufacturable layout. This process currently demands thousands of specialist engineers and spans two to three years per design cycle, making it a significant constraint on the pace of innovation in silicon.

Tattvam AI's approach is built on the conviction that chip design is fundamentally a reasoning problem. Rather than applying large language models to pattern-match across historical designs, the company is building a reasoning model that understands circuits from first principles — the constraints, trade-offs, and interdependencies at every level of the design hierarchy — in the way a world-class semiconductor engineer would. The system adds an AI layer on top of existing EDA tools from Cadence and Synopsys, augmenting rather than replacing the tools the industry already depends on.

The company aims to make custom silicon accessible to a wider range of organisations, reducing design costs and enabling rapid iteration. Rather than committing to chips optimised for the AI models of two years ago, companies will be able to align silicon capabilities with fast-evolving workload requirements. Tattvam AI plans to launch its first product in the months following its pre-seed raise, initially working with semiconductor design teams and EDA ecosystem partners to validate its approach.

Tattvam AI raised £1.3 million in a pre-seed round in February 2026, led by Seedcamp, with participation from EWOR, Entropy Industrial Ventures, Concept Ventures, and semiconductor veteran Stan Boland. The funding will be used to expand the engineering team, accelerate research, and bring the chip design product to market.
