Financial clarity for the idea stage

Plan your SaaS runway before you build.

Before spending six months building it, turn costs, funding, price, growth and churn into a clear monthly cash-flow model—and see what would have to happen for the idea to pay for itself.

No bank connections. No invented forecasts. Just your assumptions, made legible.

Illustrative product preview. It is not a customer result or a forecast.

A model that starts with the decision.

Spreadsheets are powerful, but a blank grid is an awkward place to work out whether an idea is worth building.

01

Tell the business story

Add funding, costs, price and timing as dated items and assumptions.

02

See the cash story

Inspect one coherent monthly model as a timeline or a table.

03

Test the pressure points

Find the low point, break-even path and beliefs that matter most.

The questions behind the commitment.

01

How much cash do we need?

See the funding required for the plan you are considering.

02

When does cash get tight?

Know the month, amount and events behind the lowest point.

03

When could we break even?

Make the path from customers and price to sustainability visible.

04

What has to be true?

Distinguish assumptions that are merely useful from those the business depends on.

05

How do different cases compare?

Contrast cautious, expected and ambitious choices without rebuilding the model.

For the founder who wants to see the shape of the business before shaping the product.

For solo founders and small teams testing subscription-led SaaS or digital-business ideas—not for running established company finances.
