Modern grids are too complex to trust by hand. Tessera is the foundation beneath every grid AI — finding the errors others miss, validating every answer, and refusing to speak when the proof is missing.
Every grid AI runs on a model nobody has systematically validated.
Every function in the utility stack — from real-time control to AI decision support — depends on a validated network model. The data those functions need is scattered across many source types and vendor systems. Tessera sits between them, rebuilding a validated CIM graph that every function above can act on with confidence.
Tessera is the layer between your raw GIS, asset, and SCADA data and every system that depends on it. It rebuilds the network model continuously, validates it across five independent layers, and grounds AI in data that has been proven correct — not just received.
Any source utilities actually run — GIS, SCADA, CAD, PDF schematics, satellite imagery, billing, public datasets — mapped into a CIM-conformant graph with vendor-aware schema understanding. Synthetic feeders for utilities without complete GIS. Months of manual ETL collapse to days.
Five-layer validation runs on every write — schema, topology, physics, twin-sandbox, provenance. Tiered scheduling from sub-second to nightly. Defects surface with severity, suggested fix, and a clean audit trail. Engineers approve, the model heals.
When the validated graph can substantiate an answer, Tessera grounds it and cites the records. When it cannot, Tessera refuses — explicitly, not silently. No quiet hallucination, no confident guess. Verdicts are byte-reproducible, replayable, and auditable.
Every fact in Tessera is signed at five layers of validation before it can be acted on. Nothing leaves the platform without provenance you can audit. And when even the validated graph cannot prove an answer, the platform refuses to give one — by design, not by override.
ADMS, DERMS, digital twins, AI copilots, interconnection studies — every system running on your network model is only as good as the model itself. Tessera sits beneath them, continuously rebuilding a validated CIM graph from any data you have, on any deployment posture you need.
Engineers who think in pipelines drag and connect nodes. Engineers who prefer conversation talk to an agent grounded in the validated graph. Both drive the same CIM data plane. Both are constrained by the same trust gate. Neither can act on data the platform hasn't proven.
Every ADMS, DERMS, GIS, and grid AI tool depending on a validated network model gets measurably better results with Tessera underneath. The validated graph is the contract. Everything above and below is your choice — and your existing investment.
Tessera is built to the same constraints utility procurement teams already enforce — air-gapped where it has to be, deterministic where it counts, and provably grounded everywhere it touches AI.
Runs in an isolated network on as little as 4 GB of RAM. NERC CIP-005, CIP-010 and CIP-013 compliance is maintained, not waived. Cloud, on-prem, hybrid and air-gapped — same product, same code path.
Every approval is byte-reproducible. Replay a verdict from six months ago and get the same answer, with the same audit trail. No model drift in the decision layer — by construction.
Graph-native persistence with native delta versioning. Operators see the full network state in the time it takes to refresh a screen — no ETL window, no overnight rebuild.
Every utility's validated corrections compound accuracy for peers running the same vendor stack. The longer the network operates, the harder it is to catch up — and the more your investment compounds.
In ancient Rome, a tessera hospitalis was a small clay tile broken between two parties — proof of trusted identity across strangers' thresholds. Whoever held the matching half was, by definition, to be trusted. That's the bond Tessera offers between your raw data and the systems that depend on it.
A tessellation is a pattern of discrete tiles that interlock perfectly at every scale — fractal, modular, gap-free. That's the architecture: small, validated building blocks composed into a national grid model without losing integrity at any boundary.
Tessera is shaped by engineers and operators with a combined century of utility OT experience — across distribution control rooms, ADMS and DERMS deployments, CIM standards work, and grid software at the world's largest utility software vendors. We have spent careers fixing the data layer the hard way. Tessera is the platform we wish we'd had.

We can run Tessera against an extract from your live GIS or ADMS in advance of the call — so the conversation is grounded in your actual data, not a generic walkthrough.
