Our mission
Physical AI for the buildings the world already runs.
Arcestra turns the waste already inside buildings into savings anyone can prove, starting with data centers and enterprise portfolios.
A Why we exist
The cheapest energy is the energy you stop wasting.
Demand for power is climbing fast, and the buildings that use it have barely become more efficient. That gap is where Arcestra works.
0years
Average facility efficiency (PUE) has shown little change for the sixth straight year.

B How we work
Three rules we build by.
People decide.
Arcestra recommends. Your team approves and makes every change.
Measured, not estimated.
Every saving is checked against a baseline locked before the change.
No rip and replace.
It runs on the meters, sensors and controls each building already has.
C Team
The people behind Arcestra.
D Careers
Build physical AI with us.
We are a small team building the control layer for the buildings the world already runs. The same three rules apply to how we work together.
Open door
No roles are listed right now. If you build physical AI, write to us anyway.
