01
Runway Range
Not one number but three: pessimistic, likely, and best-case months remaining. Based on 1,000 Monte Carlo scenarios.
Cash Runway
See when cash runs out, and the odds of getting there. 1,000 scenarios, not one guess.

What You Get
Probability-weighted forecasts, not single-point guesses.
02
Probability Distribution
Chance of running dry in 6 months. Likelihood of reaching 9+ or 12+ months. Know your odds, not just a guess.
03
Milestone Probability
Will you hit your target revenue before cash runs out? Set the number investors need to see and get your probability.
04
Scenario Modelling
Adjust growth rate, cost inflation, cash injection. See how each decision shifts outcomes across all 1,000 scenarios.
05
Funding Gap
How much do you need to raise? See the cash required to hit your target or extend runway, with 80% confidence, not best-case optimism.
06
Decision Deadline
When do you need to start raising? Based on the 'things go somewhat worse' scenario, not your best case. This is when you lose leverage, not when you run out.
