Process simulation
should communicate
certainty, not just results.
Equilibria is a new generation of engineering software where every simulation is transparent, every assumption is visible, and every result can be understood. At the center is the Certainty Index, helping engineers understand what a simulation predicts, and how much confidence they should place in it. Currently built around a single chemical process simulation for our MVP, we're combining engineering, modern software, and AI to help students and professionals build judgment with confidence.

PROGRESSIVE MODEL FIDELITY. BUILT FOR LEARNING.
FOUNDATIONAL
30%
Idealized models and core balances. Learn the fundamentals through idealized assumptions, phase equilibrium, and core mass and energy balances.
INTERMEDIATE
55%
Non-ideal phase behavior. Introduce activity-coefficient methods and the effects of mixture non-ideality on phase equilibrium.
ADVANCED ACADEMIC
72%
Detailed thermodynamic and equipment models. Refine phase-equilibrium predictions and introduce equipment-level effects such as tray efficiency.
PRE-INDUSTRY
88%
High-fidelity process behavior. Incorporate equation-of-state methods, hydraulic effects, and additional transport and operating conditions.
INDUSTRY
97%
Validated process models. Apply system-specific model selection, calibration, and validation against experimental or plant data.
SEE THE INTERFACE IN ACTION
Founded by an engineer.
Built for engineers.
Equilibria exists because the engineering software I needed didn't, so I built it myself. My mission is to create simulation software that is transparent, educational, and powerful enough for industry.
