Monte Carlo Cash Flow Engine

Rather than a single deterministic cash flow projection, Venatri runs 10,000 simulated scenarios using distributions calibrated to your industry, state, and inputs.

Each iteration varies:

Revenue ramp rate -- fitted from Census BDS cohort data
Operating expense variance -- from IRS SOI industry data
Customer acquisition cost -- stochastic uncertainty
Seasonal revenue fluctuation -- industry-specific patterns
Unexpected expense shocks -- fat-tailed distribution
SBA loan interest rates -- from SBA 7(a) historical data

Industry Survival Curves

We fit Weibull and exponential survival distributions to BLS Business Employment Dynamics quarterly survival rate data by 2-digit NAICS industry. This produces 1-year, 3-year, 5-year, and 10-year survival probabilities adjusted for establishment size and state.

The survival curve provides the base rate against which your specific cash flow simulation is compared. A user with strong capitalization in a high-survival industry will see better outcomes than the base rate; undercapitalized ventures in high-failure industries will see worse.

Break-Even Under Uncertainty

For each Monte Carlo iteration, we calculate the month where cumulative revenue exceeds cumulative costs. The result is not a single break-even point but a probability distribution.

Output includes median break-even month, 25th/75th percentile range, and the probability of reaching break-even within 12, 24, and 36 months.

Cash Runway Calculator

Given initial capital (savings + loans + investment), monthly burn rate distribution, and revenue ramp, we calculate months of runway. Output: P10/P50/P90 runway in months and the probability of running out of cash before reaching break-even.

SBA Loan Scenario Modeler

We model SBA 7(a) and 504 loan scenarios with actual rate spreads, guarantee fees, and repayment terms from SBA historical data. The modeler shows how leverage affects runway, break-even timing, and failure probability -- helping founders decide whether debt financing improves or worsens their viability profile.
