Runway what-ifs without spreadsheet chaos.

Ask "what if I raise prices 20%?" and get the answer off your real books

Type it to the agent you already use: open a scenario, raise every plan 20%, show me the new MRR and margin against today. The scenario starts from your live ledger — real revenue, real costs, real cash — layers the price change on top, and reads back an income statement that reflects the hike. Thirty seconds, no model to build. Then you tell it to throw the scenario away, and your books look exactly as they did before you asked.

The scenario branches off reality — it can never write back to it

A scenario is an additive overlay on your live ledger. It reads your real books as its starting point, then everything you model — a price change, a new hire, next quarter's deals, a customer churn — layers on top of that copy. It can only add; it can never alter reality. So there's no undo to get wrong and no file to corrupt: your real ledger is untouchable from inside a scenario, which means you can push on it as hard as you want.

The projection ties out because it is your books, plus the delta

Run your balance sheet, income statement, or runway under a scenario and you see the real books plus your change — not a fresh model that only agrees with reality if you hand-typed the assumptions right. That's the difference between deciding on real double-entry numbers and deciding on a guess. Want to compare paths? Clone base vs. bull vs. bear off the same ledger and read them side by side, without a single new spreadsheet tab.

Discard it, reset it, or keep it — nothing about reality moved

When you're done, throw the scenario away and it's gone; reset it clean to try again from today's numbers; or leave it standing to revisit. Every account is seeded a sandbox scenario at signup, so rehearsing anything risky is a first-class move, not a workaround. You run and discard the whole thing through your agent — no dashboard to learn, by design.

"I already have a spreadsheet — or the runway calculator I was handed"

A spreadsheet isn't your real books; it breaks the moment you stress it, and undoing a bad edit is a prayer. A standalone runway calculator is a separate model you re-key your assumptions into — so it's only ever as right as your last copy-paste. Here the what-if runs on your live double-entry ledger: your actual numbers plus the change, so it ties out, and it throws away cleanly with nothing left to unwind. It's for deciding — private, disposable. When a scenario becomes the plan you commit to and hand an investor, that's forecasting; to show one privately, point a share link at it with report sharing.
