ABOUT
An AI thatactually does the thing.
Brunu is built for people who think for a living — the analysts, the readers,
the operators, the curious. We don’t want to be your chatbot. We want to be
the brilliant, well-read friend who reads every app and acts on your behalf.
COMPANY
A product of Etra Global.
Brunu is the consumer AI flagship of Etra Global, an independent technology company building intelligence products for people who refuse to be passive in an information economy.
We started from a simple premise: the gap between knowing and acting is where most lives, businesses, and decisions break. The frontier AI models can answer almost any question. None of them, at the time we started, would actually do the next thing for you — book the call, send the email, place the order, watch the position, alert you when the world changed.
That gap is what Brunu fills. The agentic layer, sitting on the best models available, with memory of who you are and what you care about. It reads. It writes. It schedules. It forecasts. It acts. And when it’s wrong, it tells you it’s wrong.
Etra is independently held. We choose what to build and how to build it. We choose who pays us (subscribers, not advertisers). And we choose what the people who use Brunu actually need over what gets traffic.
WHAT WE BELIEVE
Four principles.
Premium, not free
We are paid by the people who use Brunu. Not by advertisers, not by data brokers, not by anyone whose interests are not the subscriber’s. That alignment shapes everything.
Models are commodities. The agent is the product.
The best LLM today will be matched by another in three months. What persists is the system around it — the memory, the agents, the integrations, the judgment.
Honest forecasts, not hot takes
Brunu Forecasts publishes calibrated probabilities and tracks its own Brier score. We will be wrong. We will say so. That’s how trust gets built.
Built for thinkers
Brunu is not for everyone. It’s for the people who already read three substacks at breakfast and want their AI to keep up. If that’s you, welcome.
