Interactive sandbox — synthetic dataSANDBOX

One engine. Every asset class.

The same A–F scoring engine grades a truck, a grid battery, a ferry and a reefer on one core. Below, the scores are computed live from synthetic sandbox data — no customer data, no signup.

Scored assets

One core, five asset classes

Five different asset classes, one TAS core. Pillar scores are shown; the weighting is proprietary (DR-154).

Reference building · public open-data feed

Same engine, a real reference building.

A sensor-instrumented Finnish home, graded from its own public open-data feed — zero data movement. Pilot rating: building metadata (EPC, age, floor area) is a placeholder until owner-confirmed.

Portfolio sandbox

Continuous rating beats a one-off test

A synthetic 50-vehicle EV-leasing portfolio (illustrative only — no customer data). Every asset is re-scored on each telemetry update — not once a year in a lab. The A–F distribution, weak assets and residual-value signals come from the same composition core every Arctura surface uses.

One scoring, many surfaces — live

The same TAS core drives NOC wallboards, buyer views and white-label embeds. Below are the real surfaces embedded — not screenshots. Synthetic / anonymised data.

Proving ground · reef.neurflow.fiREEF SYNTHETIC

What no customer will let you demo live — thermal runaway, cell-level failure, a portfolio fire — runs on a synthetic proving ground. The same production engine detects, scores and seals the evidence; the forensics open on the island, on its own domain.

Under the hood

Where the scores come from

01

Continuous TAS scoring

Continuous A–F grading across 4 pillars: battery health, usage behavior, market risk, and regulatory compliance.

02

ML predictions

ML-based residual-value and mileage forecasting. Models are re-validated against a synthetic stress substrate before production.

03

Regulatory compliance

NIS2, EU Battery Passport, AFIR, CSRD — deadline tracking and readiness scoring built into every assessment.

04

Digital certificates

18 certificate types across 14 asset-class configurations. Each certificate is independently priced and QR-verifiable.
