Speed is the superpower of computing.

Flow PPU enables next-gen CPU performance.

About Flow

Flow Computing® is a semiconductor deep-tech startup developing the patented Flow PPU (Parallel Processing Unit®), a CPU accelerator designed to unlock the next generation of processor performance.

Flow PPU is a general purpose co-processor built from the ground up to address the fundamental architectural performance-scaling challenges of multicore CPUs. It is instruction-set independent and highly configurable, enabling adoption across all CPU segments by any CPU company.

Our vision is for Flow PPU to become essential to all future CPUs. Our initial target market is AI cloud CPUs, where agentic AI has highlighted CPU performance as a critical bottleneck. Today’s CPUs cannot keep pace with the performance demands of emerging workloads, and we are actively working with prospective customers to integrate Flow PPU into their next-generation AI cloud CPUs.

Next, we plan to expand into CPUs for physical AI, where CPUs equipped with Flow PPUs can deliver the performance required for robotics and autonomous systems without the size, weight, and energy limitations of today’s hardware stack. Over time, our goal is for Flow PPUs to power consumer CPUs, including those used in laptops and smartphones.

3 key values embodied by Flow.

PERFORMANCE

We exist because traditional CPU performance has become a bottleneck for innovation, especially in AI, edge computing and advanced data analysis, which rely heavily on computing power. 

We are driven by the belief that significant leaps, instead of incremental improvements, are necessary to meet the escalating demands of new technology applications. Flow PPU technology is designed to shatter these limits with significant increases in processing capabilities, ensuring that users and the broader tech community are equipped to solve tomorrow's challenges today.

INNOVATION

We understand that true innovation doesn’t come from technology alone. It requires the right mix of people, environment, and culture. We are committed to cultivating a workspace that attracts the best global talent, encouraging them to think differently, challenge norms, and push the boundaries of what's possible. 

Our approach goes beyond achieving breakthroughs in technology. We are driven to also ensure that our innovations are sustainable and ethically grounded. We believe in responsible advancements in computing that benefit society as a whole.

IMPACT

We are dedicated to reshaping the future of technology with Flow PPU. Our mission is centered on the core belief that dramatic advancements in CPU performance can fundamentally transform industries.
 
Flow PPU enables real-time data processing and decision-making capabilities that are essential for autonomous vehicles, smart infrastructure, and real-time analytics. By dramatically reducing processing time and energy consumption, our technology doesn't just change how machines operate. It enhances the sustainability, efficiency and safety of systems that human societies rely on every day.
