Quantify your instinct

Forecasts that explain themselves.

Pluto connects what's happening in your business to what your numbers do next, and shows its working. The insight your best analyst carries in their head, made explicit, auditable, and built into every forecast.

Built by a practising FP&A professional, for the commercial teams shaping the first release.

The gap nobody owns

The link between your business and your numbers lives in one person's head.

ERPs reconcile the numbers. Analysts supply the story. Nothing connects the two, so the reasoning behind every forecast stays intuitive, unwritten, and impossible to hand over.

Known, never written

Your best analyst feels which drivers move the P&L. That judgment never leaves their notebook, or their head.

Impossible to audit

When the CFO asks "why has the forecast moved?", the honest answer is a story, not a traceable line from cause to effect.

Gone when they leave

The day that analyst walks out, years of hard-won commercial intuition walk out with them. Nothing transferable is left behind.

How it works

The business drives. The forecast follows.

Driver & passenger

Most tools forecast by staring at the past and extrapolating; the numbers drive themselves. Pluto flips it: the commercial drivers steer, and the forecast rides along. Change your view on a driver, and the numbers follow, visibly, with the reasoning attached.

Bring your numbers

Upload a CSV of your actuals and connect Pluto's external driver library: CPI, rates, FX, commodities, weather.

Find the real drivers

Pluto ranks which drivers genuinely move each line (leading, lagging, or just noise) and flags the traps.

Validate honestly

Walk-forward backtesting checks the model against history it never saw, with a plain-English verdict, not a black box.

Get the story

A board-ready narrative comes attached to every number. The explanation is built in, ready to present.

Grounded in research

This isn't a hunch. It's what the forecasting research shows.

The largest review of modern forecasting finds that structured human judgment consistently improves accuracy, and that human-guided variable selection beats automated approaches when real domain knowledge is present.
Petropoulos et al. (2022) · International Journal of Forecasting

That's the whole idea behind Pluto: put the analyst's judgment and the machine's rigour in one loop, and you beat either on its own.

The representational effect

How information is represented changes how well people reason with it. Pluto makes the drivers legible, so your judgment has something to grip.

Amershi et al. · 2014

Humans in the loop

Experts steering a model as it learns outperform hands-off automation. Pluto is built around that loop, not around replacing it.

Hyndman & Koehler · 2006

Honest measurement

Accuracy only counts on data the model never saw. Pluto backtests walk-forward, so it never grades itself on the answers.

A forecasting instrument, not a dashboard.

Every number is traceable to the drivers behind it. Reforecast across quarters, a year, or a five-year plan, and see exactly what's carrying it.

Q3 revenue is up 4.1% on the prior forecast. The move is carried by retail sales (leading, 2-quarter lag) turning up in July, partly offset by a softer CPI read. Brent had no material effect this quarter.↳ traceable to 2 drivers · deterministic engine · no numbers invented

Meet Styx

The analyst's copilot.

// AI applied where it earns its place

Styx explains what moved, drafts the commentary, and suggests drivers worth testing. The boring work, done. Ask it in plain language or reach for a command.

The numbers come from Pluto's deterministic, rule-based engine, not a language model guessing. Styx reads that working and puts it into words. It never invents a figure, and it never makes the call for you.

Our approach

What Pluto is not.

A forecasting tool for a finance audience has to earn trust before it earns a number. So here's where we draw the line.

✕
Not a reconciliation tool. Your ERP already ties out the actuals. Pluto is about what happens next.
✕
Not a penny-perfect oracle. No forecast is exact. Pluto shows the trajectory and the assumptions, and gets better each cycle.
✕
Not a black box. Every number traces back to named drivers you can inspect, challenge, and override.
✕
Not a replacement for judgment. Pluto surfaces the highest-signal drivers. The strategic call is, and stays, yours.
The materiality principle

Pluto surfaces the drivers that matter most, not an exhaustive attribution of every cent.

The output is fertile ground for a strategic conversation, not the final word. You bring the context only you have; Pluto does the rest.
