Mru builds fault-tolerant software for systems that cannot be repaired in time.
The long-term goal is software that runs for a thousand years. The work is paid for along the way by equipment that needs it now, on Earth first, then in orbit.

01 · The name
Maru: a circle, and a ship on a long voyage.
Mru is a contraction of Maru, the suffix borne by seagoing vessels. It comes from the character for “circle”, connoting completeness and safe passage on a long voyage.
The mark is that circle, with an orbit through it. It is the same on Earth and in space.
Where we are
02 · Where we are
Early and public.
Everything we have built so far is open. The next step is unattended field data, then orbit.

In the middle of the Atlantic.
We plan to work from Horta, in the Azores: close to deep-sea observatories, open ocean and the people who run them.

Operators, mission teams, partners: write to us.
A few lines are enough: the hardware, where it is, and how long it must run without a visit. We will tell you plainly whether Mru fits, including when it does not.
Requests go to the founder, not a sales team.
We reply by email. If a call helps, we suggest one.
Technical questions are welcome. The docs and code are public.
