Our Mission

Build everyday AGI. Trustworthy, consumer-grade agents that redefine humanโ€“AI collaboration for millions. Software shouldnโ€™t wait for commands; it should partner with you, amplifying what you can do every single day.

Why AGI, Inc.

Weโ€™re a stealth team of elite founders and AI researchers, with backgrounds spanning Stanford, OpenAI, and DeepMind. Weโ€™re industry leaders in mobile and computer-use agents, bringing these capabilities to consumer scale.

Grounded in years of agent research, our AI is designed with trustworthiness and reliability as core pillars, not afterthoughts.

We are supported by tier-1 investors who funded the first generation of AI giants; now theyโ€™re backing us to build the next: everyday AGI. (Watch the demo)

If you see possibility where others see limits, read on.

Build the systems our agents run on. Make them feel like magic, not infrastructure.

Our agents are only as trustworthy as the backend behind them. Every API call, every retry, every queued job is the difference between an agent that feels alive and one that feels like a chatbot. You'll own the systems that turn research into product โ€” model orchestration, agent state, partner integrations, the data plane โ€” and you'll make them fast enough, observable enough, and boring enough that the rest of the team can ship without thinking about them.

This is for the backend engineer who has been the on-call hero before, who has strong opinions about queues and idempotency, and who wants to design infrastructure for a product where the floor is "millions of devices."

๐Ÿ† Timeline of success

After 30 days โ€” You've shipped a meaningful change to the agent backend that a user would feel โ€” latency, reliability, or a new capability. You can name the three weakest links in our infra and have started fixing one. You've taken a real on-call shift.

After 60 days โ€” You own a major surface of the backend. A research breakthrough has shipped through systems you designed. Other engineers route their hardest backend questions to you. You've set the reliability and observability bar that new services have to meet.

After 90 days โ€” Our agent backend is something you'd happily defend to an infra engineer at a top-tier consumer company. You've shaped the architecture for one of our partner launches and have a strong, opinionated plan for what our infra needs to look like to support 10M devices.

๐Ÿ’ฐ Compensation

Competitive cash and meaningful equity. Top-tier relocation and immigration support. SF, in person.
