The honest problem

You do not have an idea problem. You have a choosing problem.

Most side hustles do not fail because the idea was bad. They fail because someone picked on enthusiasm, built for six weeks and launched to silence.

1

You keep researching

Another tab, another video. The idea sits exactly where it was last month.

The fixScore up to 5 ideas side by side, so the comparison really means something.

2

You build before you check

Six weeks of work, and only then you find out nobody wanted it.

The fixTest one idea for 7 days with real people before you build anything.

How it works

Five steps, in order

About ten hours across a week and a half, against the six to ten weeks an untested build can cost you.

  1. 1

    Define

    Put up to 5 ideas in one place.

  2. 2

    Research

    Real competitors and real customers. Evidence, not assumptions.

  3. 3

    Score

    8 weighted criteria, turned into a score out of 100.

  4. 4

    Validate

    A 7-day sprint, one hour a day, with real people.

  5. 5

    Decide

    Build, modify, kill or get more data, with your reasoning written down.

Honest fit check

Is this for you?

Yes, if you...

  • have more side hustle ideas than time
  • want a first online business or digital product
  • are choosing a niche, or what to make next
  • can fill in a spreadsheet (no business background needed)

Not for you, if you...

  • want guaranteed income. There is none, and this does not pretend otherwise.
  • want a business idea handed to you. This evaluates your own ideas.
  • are not willing to talk to a single potential customer

Questions

Before you buy

Does it work in Google Sheets?

Yes. Import the .xlsx in Google Sheets (File, Import, Upload, Replace spreadsheet) and the formulas, drop-downs and highlighting come across. It works in Excel too.

Do I need paid AI tools?

No. The spreadsheet works on its own, and the 30 prompts work with any free AI assistant.

I am a complete beginner. Is it too advanced?

No. Every criterion has written anchors, and the sheet ships with a full worked example you can follow cell by cell.

Will it tell me which idea will make money?

No, and be careful with anything that says it will. It shows which idea has the strongest evidence right now, and what to test next.

What if all my ideas score low?

That is a useful result. It usually means the ideas are too broad. Narrow the audience and score again.

Step 2: Choose

Stop collecting ideas. Start testing the right one.
