Advanced dynamic modeling for process optimization and decision support
Modern simulator for your modern hardware
Theo models your whole plant — biology, chemistry and hydraulics together — and solves it fast enough to explore, not just to wait. Lay out a flowsheet, press play, and watch the entire works come to life.
Watch it run
See a run unfold
Lay out a plant, press play, and Theo works through time — flow rates, effluent tables and charts updating step by step as the simulation progresses.
Integrated with AI
Have AI run and understand your models
Point a modern AI model at Theo and it can build a plant, drive the simulation, read every result and reason about your process — ask in plain English for the smallest tanks that meet your limits, or where the phosphate went, and get a traced, quantified answer.
AI builds and sizes an MLE plant from an empty canvas — a real run, sped up
Rich output
Every variable, charted
Time series, Sankey diagrams, heat maps, cycle clocks, sensitivity sweeps — every variable across the whole flowsheet, plotted and tabulated, and one click from export.

Flowsheet editor
Build any plant layout
Drag in reactors, clarifiers, thickeners, digesters and splitters, wire them together, and Theo keeps the underlying model consistent as you go — from a single line to a sprawling multi-train plant.
Your hardware, your rules
On your desk, or in your pocket
Runs natively on Windows, macOS and Linux — entirely on your own machine or in your cloud, you decide. iOS and Android clients connect to a Theo instance on your desktop or server.
I want to know more
Fast by design
Respect the rules of model building, add modern numerical methods and hardware acceleration, and a whole new range of questions becomes answerable in seconds.
True to reality
No shortcuts you would regret. Full pH chemistry and multi-step nitrification stay switched on — because your plant never turns them off.
Standing on giants
A blend of in-house experience and published, peer-reviewed models, integrated across the entire plant rather than stitched together unit by unit.
A modern interface
Tired of user interfaces from the 90s? So are we. Theo is clean, quick and intuitive from the first click.
