Flow technology enables the birth of 

CPU 2.0 - the era of SuperCPUs.

About Flow Computing.

Flow Computing is a pioneering startup based in Helsinki, Finland enabling the next generation of CPU performance for the most demanding applications, such as locally-hosted AI and general-purpose parallel computing. 

Capable of being integrated into any current or pending design architecture or process geometry, Flow provides a revolutionary up to 100-fold acceleration that is usable in standard products to enable “CPU 2.0”-levels of throughput and eliminating the need for expensive GPU acceleration of CPU instructions.

This revolutionary performance leap is achieved using the company’s patented Parallel Processing Unit (PPU) licensable architecture and compiler ecosystem - enabling developers to choose their preferred ratio of raw performance for new apps vs. maintaining legacy code and application compatibility when required. 

Flow's groundbreaking architecture also turbocharges embedded systems and data centers, for uses such as edge and cloud computing, AI clouds, multimedia codecs across 5G/6G, autonomous vehicle systems, military-grade computing and more.

3 key values embodied by Flow


Flow Computing exists 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. Our PPU technology is designed to shatter these limits with up to a 100-fold increase in processing capabilities, ensuring that users and the broader tech community are equipped to solve tomorrow's challenges today.


At Flow, 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.


Flow Computing is dedicated to reshaping the future of technology with our Parallel Performance Unit (PPU). Our mission is centered on the core belief that dramatic advancements in CPU performance can fundamentally transform industries.
Our 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 sustainablity, efficiency and safety of systems that human societies rely on every day.
