Exa is making reconfigurable chips for AI, offering superior speed and energy efficiency compared to traditional GPUs/TPUs/LPUs.

Our chips automatically adapt themselves to each specific AI model, overcoming the von Neumann bottleneck, (a common limitation in standard systems). By optimizing for each AI architecture, we significantly boost both inference and training speeds while reducing energy consumption.

Imagine having hardware tailored to your AI model, whilst still maintaining the flexibility of a GPU. This way, you won't need to re-manufacture your hardware each time you change your model architecture, all while still benefiting from the speed and efficiency of specialized hardware, saving data centers and compute clusters hundreds of millions of dollars every year!

### Energy efficient chips for AI

Exa is making reconfigurable chips for AI, offering superior speed and energy efficiency compared to traditional GPUs/TPUs/LPUs. Our chips automatically adapt themselves to each specific AI model, overcoming the von Neumann bottleneck, (a common limitation in standard systems). By optimizing for each AI architecture, we significantly boost both inference and training speeds while reducing energy consumption.

Exa Laboratories

Founded:2024

Team Size:2

Location:San Francisco

### Active Founders

### Elias Almqvist, Founder/CEO

Elias is the CEO of Exa Laboratories. A self-taught engineer since age 9, he studied CS & CE at Chalmers University of Technology, worked part-time as an embedded software engineer, and was involved in various PhD aerospace projects as an undergrad. After dropping out in his second year, he founded Exa to accelerate AI innovation and elevate human consciousness. Greater and more sustainable compute drives better AI and scientific breakthroughs.



### Prithvi Raj, Founder

CTO and co-founder of Exa Laboratories. Before Exa, I was pursuing my MEng as part of a world leading lab, (the Computational Stats & ML Lab at Cambridge). Here, I fell in love with scientific machine learning - a field that requires bespoke neural network architectures and extreme hardware efficiency. I'm here to provide these so that AI can start solving the game-changing problems that it was originally promised to address.



### Company Launches

[### Exa Laboratories - 27.6x more efficient chips for AI 🔥🚀](

### TL;DR:

We're building reconfigurable chips for AI that are up to 27.6x more efficient and powerful than the H100 GPUs. This could save data centers hundreds of millions to billions in annual energy costs.

### Meet the Team

Hello! We're [Elias]( and [Prithvi]( from [Exa]( We're developing **reconfigurable chips for AI** that are up to around **27.6x\* more efficient and performant** than the modern H100 GPUs.

### The problems!

The AI industry faces critical challenges threatening its sustainable growth:

1.  **Unsustainable Energy Consumption**: Modern GPUs consume 600-1000 W per unit, creating massive scaling issues for data centers. Large data centers face energy costs in the hundreds of millions to potentially billions each year. **GPU power draw seems to be increasing with each new release**, while **compute per area has remained the same** for the past 5 years.
2.  **Exponential Compute Demand**: With AI advancements, computational power demand is rapidly increasing. Unchecked, this trend could lead to an energy crisis, impeding AI progress and costing data centers billions of dollars.
3.  **Hardware Limitations**: **Current fixed architectures constrain AI innovation**. They lack the versatility to efficiently support diverse AI architectures and custom neural network designs crucial for solving real-world problems.

### The solution.

Exa's polymorphic computing technology addresses these challenges:

*   **Reconfigures for each AI model architecture**, maximizing efficiency and versatility
*   Supports diverse approaches, from **transformers** and **GPTs** to novel AI architectures (e.g., the new [**Kolmogorv-Arnold Networks (KAN)**](
*   Early simulations indicate potential efficiency gains of up to **27.6x** over the H100 GPUs

**This technology could save data centers hundreds of millions to billions in annual energy costs**, significantly reducing operational expenses and environmental impact.

### Hear from the founders

#### How did your company get started? (i.e., How did the founders meet? How did you come up with the idea? How did you decide to be a founder?)

Elias, originally from Sweden, was motivated by the challenge of running large language models on FPGAs to combat the high power consumption of modern GPUs. During a week-long event in London, Elias met Prithvi, whose expertise in electrical engineering, generative AI, and scientific research perfectly complemented his own. They quickly recognized that advancing science and technology required a new computing paradigm - one that was both more powerful and sustainable. Driven by a shared passion for advancing humanity and accelerating technological progress, Elias, who had recently dropped out of university, and Prithvi, who had just graduated, founded Exa to revolutionize computing and push the boundaries of (artificial) intelligence.

#### What is your long-term vision? If you truly succeed, what will be different about the world?

Exa's long-term vision is to eliminate hardware constraints in computing and artificial intelligence by creating hardware that is **fully reconfigurable**. This would remove the need to replace underlying hardware to support the latest AI models - a crucial consideration given the anticipated chip and silicon shortages in the coming decades. Given its reconfigurability, our hardware would therefore open up new possibilities in scientific machine learning (_beyond just sentence generation_), where flexible AI design is essential. This capability could lead to the **discovery of new equations** and **scientific breakthroughs**, fulfilling one of the original promises of artificial intelligence and machine learning in advancing human knowledge, and solving the worlds most pressing problems. We aim to enable individuals, organizations, and governments to run large-scale AI models on their own hardware, making AI **fully decentralized** and **safe** while significantly reducing energy costs. With modern GPUs, this would be impossible. As the AI revolution accelerates, models are becoming larger, and AI usage is surging exponentially. This trend is leading data centers to consume increasingly massive amounts of energy, potentially requiring the installation of dedicated power plants to meet demand in the future. For humanity to advance, we must discover a more sustainable way to run AI models. Exa is dedicated to providing this solution. Without it, we risk excessive energy consumption, which could potentially lead to the end of humanity as we know it. _Exa computing is the most optimal way forward._
