The accountability layer
for AI infrastructure.
Pleione measures a data center's water, heat and power on the pipe, signs a record anyone can verify offline, and recovers what the physics allows.
Water decides how big AI gets.
Compute is scaling faster than the planet can cool it. Water and power are now the hard physical limits on the AI buildout, and the number that gates every new facility is one no one can verify.
The number that decides the permit. Nobody can check it.
Jurisdictions started counting in 2025–26, and they count in opposite directions. Every path runs through a water figure no third party can verify, and every hyperscaler has pledged “water-positive by 2030” on exactly that unverifiable number.
Not your number
Utilities report water sales by customer type, a billing figure that says nothing about what you returned.
$10,000 / day
Civil penalty for an incomplete water report. The penalty attaches to the reporting, not the volume.
Method unwritten
Every licence holder reports actual use publicly; the province hasn't written the measurement standard yet.
Approval, not proof
Closed-loop cooling prioritised, with nothing requiring proof a loop is real. Mississauga returns to council this fall.
Guardian reads the whole loop as one live system.
- Measure intake, return, reuse and quality on the pipe, no estimates.
- Sign every reading, hashed and chained, on-site the moment it's made.
- Verify offline, a regulator recomputes the record with the internet switched off.
- Deterministic safety, Guardian proposes; a safety layer decides. No language model touches a valve.
Others sell a box. We own the record.
The defensible asset isn't hardware, it's the signed, offline-verifiable statement and the standard it sets. Auditable by construction, portable across every site.
Measured, not modeled
Every figure read on the pipe with instrument provenance carried through. No back-calculation from a utility bill.
Recompute offline
Each record hashed and linked to the last, signed to a key. It verifies with no trust in the operator, or in us.
Won't fake a pass
Where evidence is partial, the record says so. For an accountability brand, refusing is the feature.
Land as software. Recovery is the expansion.
We sell the verified record first, asset-light, high-margin, shippable today. The Node opens a second, larger line once the software owns the account. The value, and the equity, live in the software layer.
The Node recovers water from the facility's own waste heat.
A containerised recovery plant that turns rejected thermal energy into reclaimed water on site, and signs what it recovers to the same standard. Drawn to the level a fabricator can quote; staged after the software proves the account.
In build · long-lead items identified · recovery performance counted as upside, never as fact.
Built for the people who carry the risk.
Hyperscalers
A defensible water-positive record for the facilities under the most scrutiny.
Colocation
A per-tenant, per-site number you can put in a contract and stand behind.
Utilities & regulators
Independent verification of what a facility in your watershed actually takes and returns.
Communities
Local supply protected first, provable to the people who live next to the load.
Every new AI facility is a physical resource system, and 17 billion gallons a year, climbing, flow through rooms that can't yet prove their number.
Pulled into the room, not pushing in.
Mississauga City Council
Invited to present on data-center water and siting, the regulatory thesis, live and on the record.
Ontario Water Consortium
Opening a path to pilot and validate with Ontario water utilities and researchers.
Active seed conversations
Deep-tech seed funds reaching out off first contact. Guardian live, model specs validated, site shipped.
Four disciplines, one system others can't staff.
Water accountability sits at the seam of chemistry, mechanics, thermal and controls, the reason no one has done it end to end. Pleione is built by operators plus a bench that has each shipped the real thing.

I&E, 40 yrs
Instrumentation & electrical from oil & gas, custody-grade metering and interlocks.
Software now, recovery next, the ledger after.
Guardian live
Measure, sign, verify at first sites. The record ships today.
Ontario pilots
Utility & facility pilots via OWC; first paid measurement deployments.
Node validation
Build & validate the first recovery unit with lab oversight.
Resource ledger
Every site's take, return & reuse, the resource layer for the physical AI economy.
Raising US$2M pre-seed.
- Scale Guardian, measurement & verification across first paying sites.
- Build & validate the first Node, prove recovery to the same signed standard.
- Stand up first deployments, convert pilots (Ontario / OWC) into references.
