A model people can actually use

Write the formula.
Change the inputs.
Share the answer.

Build with readable, named formulas. Test a new assumption in the results pane. Let someone else explore the answer without editing your model.

Try Cast See how it works
01 / WRITE

Formulas you can read.

profit = revenue - costs stays visible beside the results. No formula columns to copy or drag.

02 / TEST

Answers you can change.

Change an input in Results. Cast recalculates every connected answer without editing the formula.

03 / SHARE

A view they can explore.

Send an input-only view. Others change exposed values and see new results without editing the model. Requires Pro.

The basics are better here

Write the math once. Work with it everywhere.

Cast’s formula language keeps the model readable. The everyday tasks around it take a few clicks.

Read the formula.

Write a named relationship where everyone can see it. No A4*B2 to decode or formula column to copy.

profit = revenue - costs | result

Forecast in a few lines.

Give Cast a starting value and a rule for the next period. It builds the whole time series, year by year.

base = $360,000
growth = 8%
forecast 5 years:
  Sales = previous Sales * (1 + growth), starts at base | chart

Save a scenario.

Change an input and click Save Scenario. Cast puts the cases side by side, across the named inputs and results.

Chart it with one flag.

Add | chart to a result. On a forecast series, Cast draws a line chart as the periods unfold.

Let someone try the numbers.

Share an input-only view. They can change exposed values and see recalculated results without touching the model code.

Export to Excel when you need it.

Download an .xlsx workbook for your existing workflow. Supported calculations stay live as Excel formulas; the rest keep their values and notes.

Input-only, results-only sharing requires Pro. Exported functions without an Excel equivalent are included as values with notes.

Built for the questions you ask

One Cast. Your kind of work.

The same powerful tools, applied to the decisions that matter to you.

Cast for finance

Trace every assumption to the return.

Underwrite a deal, build an operating plan, and see which assumptions change the result.

  • Five-year LBO forecast and debt sweep
  • IRR, MOIC, carry, covenants, and value creation
  • Sensitivity, scenarios, and Monte Carlo on one model
  • Named formulas and an editable data grid

Go deeper than a single answer

Serious analysis.
Surprisingly approachable.

Explore the what-ifs. Measure the uncertainty. Discover something you didn't know to look for.

One named model. Multiple ways to test it.Real Cast output
Sensitivity analysis

What happens to the payment if rates change?

Sweep two inputs at once. Cast calculates every combination and turns the results into a heatmap you can explore.

Sensitivity analysis

Find the assumptions that change your answer.

Sweep two inputs at once. Cast calculates every combination and turns the results into a heatmap you can explore.

Risk & uncertainty

See the range. Understand the downside.

Give your uncertain inputs ranges or distributions. Cast runs thousands of simulations and shows the outcomes, percentiles, and downside.

Predictive models

Build a model. See what drives it.

Choose what you want to predict. Cast trains and compares models, ranks the drivers, and reports how well each model predicts.

Symbolic regression

Find the equation hiding in your data.

Cast searches for mathematical relationships and compares their accuracy and complexity. Inspect a readable equation you can use in your model.

Optimization & backsolving

Start with the outcome.
Find what gets you there.

Ask for the best settings, the maximum safe load, or the debt a deal can carry. Cast works through the relationships and shows the result.

AI, built into the work

Talk it through.
Build it in Cast.

An assistant that knows your model, works with your data, and helps you go from a question to an analysis you can inspect.

Describe what you want.

Type or speak. Cast builds and edits models, explains results, and proposes changes to your data.

See code that has already run.

Generated model code must pass Cast’s parser and evaluator before it appears. Failed code is repaired or withheld. You approve changes.

Investigate the next question.

Cast frames hypotheses, runs analyses, and records evidence. Edit a step, rerun it, and export the findings.

Explore AI research

A successful code check confirms execution. You still review assumptions and conclusions. Chat, web search, and AI research use monthly credits.

A question becomes an investigation
Actual Cast research output. Each hypothesis keeps its evidence and a Supported, Not supported, or Mixed verdict.
Bring the world into your model

Your data is the starting point.

Work with a CSV, find a public source, or ask Cast to set up a connection.

Import and shape your data.

Upload a CSV, edit the grid, handle missing values, filter rows, and build calculated columns with a preview before applying.

Search with sources.

Ask Cast to find current information or API documentation. Follow the source links and inspect the evidence yourself.

Build a custom connector.

Cast searches and reads API docs, then proposes a connector. Review it, click Add, and pull values into your model with fetch().

Live sources may require your own API key or account. Connector proposals include the reviewed documentation.

From your workspace to theirs

Make the work
easy to share.

Keep the model, the results, and the reasoning together.

A model people can explore.

Share a view with editable inputs and live results, without exposing the code. Choose a link to your saved work or a frozen snapshot. Input-only sharing requires Pro.

An Excel file people can keep using.

Export your model whenever you need an .xlsx handoff. Supported calculations remain live formulas. Scenarios and analyses get their own tabs; functions without Excel equivalents keep values and notes.

A clear record of how you got there.

Export research reports with findings and methods. Save versions, compare changes, and restore earlier work.
