Our Modeling Framework

Three Statement Financial Models using the Leontief Method

Our proprietary modeling framework is built taking into consideration the "Input-Output" ideas put forward by the Russian-born American Nobel Prize-winning scientist, Dr. Wassily Leontief.

About Dr. Wassily Leontief

Wassily Leontief (1905–1999) was a Russian-born American economist who revolutionized the field of Economics by creating Input-Output analysis, a method of mapping the complex interdependencies within an economy. His work was so foundational that he was awarded the 1973 Nobel Prize in Economics.

But his influence didn't stop there. Leontief was a master mentor; four of his doctoral students also went on to win the Nobel Prize, proving that his rigorous approach to structural data is the gold standard for understanding complex systems.

From Economic Theory to Business Strategy

While Leontief applied his logic to nations, we apply it to your business. We transform the "Input-Output" concept into the most robust three-statement models available today.

  1. STEP 01
    Inputs

    Every operational driver is captured as a structured input.

  2. STEP 02
    Engine

    A linked three-statement engine propagates the math.

  3. STEP 03
    Outputs

    P&L, Balance Sheet, and Cash Flow update in real-time.

Every operational driver (Input) is mathematically linked to your P&L, Balance Sheet, and Cash Flow (Output). If one lever moves, the entire ecosystem updates in real-time.

Our models are dynamic, designed for advanced scenario testing. We categorize variables by sensitivity (High, Medium, Low), allowing you to run "what-if" simulations that prepare you for any market condition.

We take the mathematical complexity and distill it into clear, executive-level visuals that make decision-making effortless for boards and investors.
