Everyone asks it.
Few do the sums.

A lot of people have a business idea in a notes app, or a side project that makes a bit of money, and a question they ask themselves on the commute: could this be the thing? Could it pay the bills?

The usual tools want a business plan before they tell you anything. We think that’s backwards. You should get something useful in a minute, and then decide whether it’s worth more of your evening.

A good idea is not a resignation letter.

Two questions, never one number

Whether an idea is promising and whether you can afford to leave your job are different questions. A brilliant idea can be years from paying a mortgage; a dull one can cover it comfortably. So the Business Idea Score rates the idea, the calculator does the sums on your money, and we never add them together into something flattering.

Then, what to do about it

A score changes nothing on its own. Save your result and we turn it into a plan: the single most useful thing to do next, with the reasoning attached so you can disagree with it, and the message written for you. Tell us what happened and the next move is chosen from the result. That part grew out of Do This Next, which is what this product used to be called.

Some things we won’t do

We won’t tell you to hand in your notice. We won’t post anything on your behalf. We won’t invent evidence: if we say something about your business, it came from what you told us or what’s on your website, and where it’s our inference we say so. We won’t send your salary or savings anywhere: the calculator runs in your browser.

Honestly, where we are

This is new. There are no testimonials on this site because we haven’t earned any yet, and no user numbers because inventing them would be a strange start for a product built on honest assessments. The score and the calculator are real and free. If the advice turns out to be no better than what you’d have thought of yourself, tell us, and we’ll either fix it or stop.
