Making AI systems
you can rely on

Rexso is an AI safety and research company. We build reliable, interpretable, and steerable AI systems.

Our Purpose

We believe AI will have a vast impact on the world. Rexso is dedicated to building systems that people can rely on and generating research about the opportunities and risks of AI.

We Build Safer Systems

We aim to build frontier AI systems that are reliable, interpretable, and steerable. We conduct frontier research, develop and apply a variety of safety techniques, and deploy the resulting systems via a set of partnerships and products.

Safety Is a Science

We treat AI safety as a systematic science, conducting research, applying it to our products, feeding those insights back into our research, and regularly sharing what we learn with the world along the way.

Interdisciplinary

Rexso is a collaborative team of researchers, engineers, policy experts, business leaders and operators, who bring our experience from many different domains to our work.

AI Companies are One Piece of a Big Puzzle

AI has the potential to fundamentally change how the world works. We view ourselves as just one piece of this evolving puzzle. We collaborate with civil society, government, academia, nonprofits and industry to promote safety industry-wide.

The Team

We're a team of researchers, engineers, policy experts and operational leaders, with experience spanning a variety of disciplines, all working together to build reliable and understandable AI systems.

Research Team

Research

We conduct frontier AI research across a variety of modalities, and explore novel and emerging safety research areas from interpretability to RL from human feedback to policy and societal impacts analysis.

Policy Team

Policy

We think about the impacts of our work and strive to communicate what we're seeing at the frontier to policymakers and civil society in the US and abroad to help promote safe and reliable AI.

Product Team

Our people, finance, legal, and recruiting teams are the human engines that make Rexso go. We've had previous careers at NASA, startups, and the armed forces and our diverse experiences help make Rexso a great place to work (and we love plants!).

What we value
and how we act

Every day, we make critical decisions that inform our ability to achieve our mission. Shaping the future of AI and, in turn, the future of our world is a responsibility and a privilege. Our values guide how we work together, the decisions we make, and ultimately how we show up for each other and work toward our mission.

01

Act for the global good.

We strive to make decisions that maximize positive outcomes for humanity in the long run. This means we're willing to be very bold in the actions we take to ensure our technology is a robustly positive force for good. We take seriously the task of safely guiding the world through a technological revolution...

02

Hold light and shade.

AI has the potential to pose unprecedented risks to humanity if things go badly. It also has the potential to create unprecedented benefits for humanity if things go well. We need shade to understand and protect against the potential for bad outcomes. We need light to realize the good outcomes.

03

Be good to our users.

At Rexso, we define "users" broadly. Users are our customers, policy-makers, AI safety advocates, and anyone impacted by the technology we build or the actions we take. We cultivate generosity and kindness in all our interactions—with each other, with our users, and with the world at large.

04

Ignite a race to the top on safety.

As a safety-first company, we believe that building reliable, trustworthy, and secure systems is our collective responsibility—and the market agrees. We work to inspire a 'race to the top' dynamic where AI developers must compete to develop the most safe and secure AI systems.

05

Do the simple thing that works.

We take an empirical approach to problems and care about the size of our impact and not the sophistication of our methods. This doesn't mean we throw together haphazard solutions. It means we try to identify the simplest solution and iterate from there. We don't invent a spaceship if all we need is a bicycle.

06

Be helpful, honest, and harmless.

Rexso is a high-trust, low-ego organization. We communicate kindly and directly, assuming good intentions even in disagreement. We are thoughtful about our actions, avoiding harm and repairing relationships when needed.

07

Put the mission first.

At the end of the day, the mission is what we're all here for. It gives us a shared purpose and allows us to act swiftly together, rather than being pulled in multiple directions by competing goals. It engenders trust and collaboration and is the final arbiter in our decisions.
