More sustainable buildings.
In a more affordable way.
Our mission is to create more sustainable buildings in a more affordable way — by putting the right data in the hands of everyone who shapes buildings, at the earliest moment it can make a difference.

The ideas behind the name.
Quick Sustainable Architecture Design — fast, integrated sustainability for every design stage.
Quantum Satis — Latin for "as much as is sufficient." Tools that meet real needs without wasting resources, time, or effort.
Oli means light in Tamil — the language of our co-founder Sundar. Oli.ai is the intelligence inside QSAD: illuminating the path toward better, more sustainable design.
The four S's.
Quick, user-friendly, minimal effort. If you can sketch a building, you can simulate it in QSAD.
As much as is needed, no more. Buildings that meet human needs without excess consumption or complexity.
Reduce energy demand, CO2 emissions, and cost inefficiency at every stage of the building lifecycle.
From energy performance to full Life Cycle Analysis (LCA) — QSAD is built to grow with the profession's needs.
Different backgrounds.
One tool.
We bring together architectural practice and machine intelligence — and that's exactly the point. Our background spans hands-on construction experience and licensed architecture, shaping the QSAD parametric physics engine to reflect how buildings are actually conceived and built. On the AI side, we built the intelligence layer behind Oli.ai to turn complex simulation data into decisions you can act on. We share one goal: making sustainable design accessible from the very first sketch.
