Baya Systems raises $36m for chiplet tech

Baya Systems in the US has raised $36m for its chiplet technology just six months after emerging from stealth mode with backing of $11m.

The Series B funding round was led by Maverick Silicon with a strategic investment from EDA tool maker Synopsys, with current investors including Matrix Partners and Intel Capital reinvesting into the company.

The company launched in June 2024 having raised $11m in a Series A round according to Pitchbook.

Baya’s WeaverPro software generates IP for chiplets using die-to-die (D2D) standards such as Ultra Accelerator Link (UALink). The tool generates a chiplet-ready network with a verifiable protocol level cluster perimeter as well as multi-level cache coherent fabric IP with co-optimization of the cache, memory and IO stacks, all driven by the D2D analysis.

This enables continuous refinement of data-driven architecture and micro-architecture development from initial specification through post-silicon tuning for AI and high performance chips, with built-in simulation and workload analysis.

“Baya Systems has executed ahead of schedule on building the team, the technology and the products that deliver on its vision to solve the high-performance system design challenge for the semiconductor industry,” said Stan Reiss, general partner, Matrix Partners. “This has uncovered a much larger scope for the company, and in our view, this new infusion of capital is necessary to extend leadership and capitalize on that opportunity.” 

“Designing increasingly complex combinations of CPUs, GPUs, neural network accelerators and other processors is a brute-force solution that the industry cannot rely on forever. It simply comes with too many risks: high re-engineering costs, difficulty scaling and potentially hitting the market with sub-par metrics,” said Dr. Sailesh Kumar, founder and CEO, Baya Systems. “Baya’s performance-focused, software-based approach, coupled with our unique transport and modular fabric IP, is designed from the ground up to produce complex multi-die solutions that are correct by construction with a simplified design process.”  

The first, and only customer so far is Tenstorrent, which has licensed Baya technology for its AI and RISC-V chiplet designs along with physical layer D2D interconnect IP from Blue Cheetah. However Tenstorrent is run by Jim Keller, who is also founder and chair of Baya.

“Generative AI and multimodal compute have clearly shown that the real challenge has transitioned from compute engines to data movement and connectivity to truly deliver on the performance and efficiency needs of AI acceleration and scale compute infrastructure and communications,” said Andrew Homan, Managing Director at Maverick Silicon. “The team at Baya Systems is uniquely positioned to fill this critical gap in the industry with its WeaverPro, WeaveIP and other solutions.”
