Pimsoft Introduces Sigmafine Engineer, AI Grounded in First-Principles Operational Models
Milan, Italy, May 20, 2026 – Pimsoft, the Italy-born specialist in industrial data quality and the company behind Sigmafine, unvailed the capabilities of the first release of Sigmafine Engineer, its first AI product trained on the same first-principles plant model that Sigmafine has run across refineries, petrochemical plants, LNG, and metals & mining sites and other process industries for more than three decades. Sigmafine Engineer answers questions, retrieves operational data, and executes reconciliation operations — securely, with human approval that touches reconciled data.
Sigmafine Engineer reaches official launch in November 2026, with public preview for select customers in September 2026.
“Industrial AI is gated by the quality of the data behind it. Sigmafine has produced decision-grade operational data for the world’s largest process plants for more than thirty years. Sigmafine Engineer brings that operational truth into a new era of engineering-grade AI.
We didn’t build a generic AI chatbot for industrial data. We built operational AI grounded in first-principles engineering models — capable of retrieving knowledge, executing workflows, identifying operational issues, and accelerating decisions across the plant.” - Mariana López Espiño, General Manager at Pimsoft
Why Now: Industrial AI Is Gated by Data Quality
Generic AI assumes industrial data is already trustworthy. Process industries know it isn’t.
Historian data is noisy. Transfers are incomplete. Measurements drift. Operational context is fragmented across systems, workflows, and engineering models. As companies race to deploy AI copilots on top of OT environments, many are discovering the same problem: AI inherits the uncertainty of the data beneath it.
Sigmafine approaches industrial AI differently.
For more than three decades, Sigmafine has reconciled mass, energy, volume, and component balances across the world’s largest process plants using first-principles operational models. Sigmafine AI is built on top of that reconciled operational truth — enabling engineers and operators to retrieve information, execute workflows, and interact with plant operations through engineering-grade AI grounded in validated operational context.
What Sigmafine Engineer Does on Day One (Private Preview, July 2026)
- SSP Help — Customer questions answered inside the product using Sigmafine Support Portal knowledge. Eliminates the round-trip to documentation and support tickets.
- View Missing Transfers — Surfaces incomplete material transfer records to accelerate period-end reconciliation. Productizes time-to-close reduction work pioneered at Sigmafine User Conference.
- Auto Tolerance — Proposes and applies tolerances grounded in the customer’s model, cutting repetitive setup and accelerating reconciliation cycles.
- Simple Data Retrieval — View displays, inspect elements, search across displays, query case journals, view diagnostics, and search transfers — all through natural language. No new query syntax to learn.
What Comes Next (Public Preview, September 2026)
By the September public preview, Sigmafine Engineer extends into complex operations, full Studio analytics, and advanced cross-case retrieval:
- Complex Operations — Generate Report, Create Display, Edit Display, Link Reports to Settings, Query Audit History, Query Display Import History.
- Studio Operations — Create Analytics Project, Run/Debug/Monitor Analysis, Translate Analysis, Validate Code Expression, Convert Whiteboard to Display, Package & Share.
- Advanced Retrieval — Composition tracking, component balance and thermodynamic tables, complex transfer filtering, cross-case aggregation, and symbol library search.
Plant-Grade AI: Built for Safety-Critical Operations
Sigmafine Engineer is designed for the operating realities of process industries. Pimsoft defines plant-grade AI by three commitments:
- Grounded in the plant model — not a general-purpose language model speculating about a customer’s plant, but reasoning anchored in the first-principles model already running in the customer’s control room.
- Human-in-the-loop on every action — running a workflow, creating a case, managing adjustments: Sigmafine Engineer proposes; the engineer approves. No autonomous changes to reconciled data.
- Deployed inside the customer’s perimeter — Sigmafine Engineer runs in the customer’s tenant. Production data does not leave the customer’s environment.
In a market crowded with general-purpose AI assistants making absolute claims, Sigmafine Engineer takes a different posture: an AI engineer that knows your plant.
