Runway is a free-to-start web app that lets you adjust a handful of plain-English business numbers and instantly watch a complete, professional financial picture redraw itself. No spreadsheets. No accounting degree. No "Calculate" button — you move a slider, and everything updates before you've let go of the mouse.

The actual app — flip between Financials and Analytics. Every number is live; there is no "Run" button.
If you're great with math and systems but finance feels like a beancounter dark art, this is for you. You don't need any prior business knowledge to get value in the first 60 seconds.
Most finance tools force a brutal trade-off: simple ones are toys that teach nothing real, and powerful ones are 200-row spreadsheets that paralyze a beginner. Runway breaks that trade-off — you adjust a few intuitive levers and get back a genuine, professional three-statement model that always adds up.
The things you have to do are simple. The thing you get to understand is the real deal.
Every change updates everything on screen in under a tenth of a second. Because the feedback is immediate, the link between what you changed and what happened becomes impossible to miss — that's how intuition actually forms.
A quick, free sign-in and you're straight into a live, working model — no "choose your business type" wizard, no setup, no spreadsheet to build. The full simulator and every chart are free to use.
A real three-statement model is usually intimidating. Runway presents it so cleanly — calm layout, clear grouping, plain headings — that a complete beginner can follow it. Depth without the dread.
Real financial terms, so you learn the vocabulary founders use — but every term has a plain-English tooltip. Burn → "how much cash you lose each month." Runway → "how many months until you run out of cash."
Ask it anything. It's not a generic chatbot — it's anchored to your current model. Ask "why did my cash run out faster?" and it answers about your actual numbers, in an encouraging, plain-spoken voice. The co-pilot is part of Runway Pro.
The simulator, the full three-statement model, and every chart are free to use. Runway Pro adds the AI co-pilot, cloud-saved & compared scenarios, and CSV / Excel / PDF export.
"When I spent more on marketing, I ran out of cash sooner." You feel the link instead of memorizing a rule.
Watch the verdict flip from "Not Viable" to "Viable" through your own decisions, and see exactly which levers mattered.
Once the relationships click, you can reason about any startup through a financial lens — not just your own.
A full Income Statement, Balance Sheet, and Cash Flow Statement — with a live check that proves the books always balance.
Runway, monthly burn, cash balance, breakeven month, net margin, and a clear Viable / Not-Viable verdict — with the reasoning spelled out.
Revenue, cash balance, the P&L waterfall, burn, margins, expense breakdown, and more — each redrawing with every edit.
A headline bar stays pinned above everything, in view at all times — so the consequence of any change is never more than a glance away.
Runway · Monthly burn · Cash balance · Breakeven · Net margin · Viability verdict
Ask about your model, or about finance and business in general.
Stuck on why your cash ran out faster, or what "working capital" even means? Just ask. The co-pilot reads your current model and answers about your actual situation — in plain, encouraging language.
It'll happily teach any finance or business concept, then tie the lesson straight back to the levers on your screen. The co-pilot is a Runway Pro feature.
Tested against thousands of random and extreme scenarios — the books balance every month, for every input.
Your working model lives in your own browser and survives a refresh. Pro adds cloud-saved, named scenarios you can compare.
Your working model stays in your browser, and the AI co-pilot is never logged. We don't sell your data; saved scenarios (Pro) are stored to your account. See our privacy page.
With Pro, download your full model as a CSV, Excel, or PDF file in one click, for sharing or deeper analysis.
Keyboard-operable, screen-reader-friendly, readable contrast in light and dark themes.
The simulator and every chart are free to use; Pro unlocks the co-pilot, saved scenarios, and export.
