The zero-baseline principle — why AtlasBurn assumes nothing
Most dashboards fill the gaps in your data with defaults and hand you a confident number. We made the opposite choice, on purpose. A field note on building AtlasBurn.

When you build a forecasting tool, there's a constant temptation to be helpful by filling in what the user hasn't given you. No capital reserves entered? Assume an industry average. Not enough history? Extrapolate from a week. It makes the product feel finished. It also makes it lie.
Defaults are comfortable lies
A default is an assumption wearing the costume of a fact. The moment you fill a missing input with "a reasonable number," the output stops describing this company and starts describing an imaginary average one. The founder can't see where their real data ended and your guess began — so they trust a forecast that's partly fabricated.
For a runway number, that's not a small sin. Someone makes a fundraising decision on it.
A wrong number delivered confidently is worse than no number. At least "we don't know yet" tells you the truth about what you know.
NOT_READY is a feature
So AtlasBurn's engines refuse to guess. The variance engine won't compute volatility on fewer than seven days of history — it returns NOT_READY and tells you what's missing. The probabilistic engine won't run without real capital reserves, burn, and volatility. Every economic input has to come from you or your telemetry. Nothing is silently assumed.
It's a worse first-run experience, honestly. An empty dashboard that says "give me more data" is less satisfying than a dashboard full of confident charts. We chose it anyway, because the alternative is a tool that's most wrong exactly when you have the least data — which is exactly when you're most likely to believe it.
What zero-baseline buys you
The payoff is trust. When AtlasBurn shows you a runway distribution, every part of it traces back to something real — your reserves, your observed burn, your measured volatility. There's no house-average smuggled into the tail. The number is yours, or it doesn't exist yet.
Building in the open means owning the unglamorous decisions too. This is one of them: we'd rather show you less and have it be true.
