The two-stage method
Discover the direction
A guided conversation, not a form. You answer questions about your skills, your capital and the life you actually want, and it narrows the field to two to four directions worth taking seriously, each with its own capital requirement, time to revenue and risk level.
Start discovery →Stage 2Stress-test the idea
Once you have a direction, or already have an idea in mind, the stress-test interrogates it against the customer, the competition, the money and your personal fit. You leave with the one number that decides whether it holds up.
Start the stress-test →What the stress-test actually checks
An idea that sounds reasonable in conversation does not always survive being written down with real figures attached. The stress-test works through four dimensions before it gives you a result.
Customer
Who specifically will pay, and whether the price they will pay covers what it costs you to serve them.
Competition
Who else is already serving that customer, and what would actually make someone choose you over them.
Money
Break-even volume, runway, and what the business needs to sell per day before it pays you anything.
Personal fit
Whether the capital, time and risk the business demands match what you actually have to give it.
Where the free tools fit
The stress-test draws on the same maths as two standalone tools, which you can use on any idea, including one you are evaluating outside this process.
The break-even calculator works out how much you need to sell, per day, before the business covers its costs. The runway calculator takes your savings and monthly burn and tells you how long you have before the money runs out. Both are free and do not require an account.
Start where you are
You want your own business but you do not know what. Start with discovery. It is a conversation, not a questionnaire, and it ends with two to four directions worth taking seriously.
You already have an idea and need to know if it holds up. Go straight to the stress-test. Bring whatever numbers you have. Where you do not have them yet, the tool will show you what to go and find out.
Frequently asked questions
How do I know if my business idea is any good?
A good idea is one that survives contact with specifics: a customer who will actually pay, a competitive set you can realistically beat, a cost structure that leaves room for you to get paid, and a fit with your own skills and capital. Most ideas are not tested against all four before money is spent. The stress-test exists to check them before you find out the hard way.
What does the stress-test actually check?
Four things: who the customer is and whether they will pay what you need them to, who else is already serving that customer and why you would win, what the numbers look like once real costs are in, and whether the business suits your own capital, time and risk tolerance. It ends with a single figure that reflects whether the idea, as specified, is worth pursuing.
I don't have a business idea yet. Where do I start?
Start with the discovery stage rather than the stress-test. It works from your skills, the capital you have available and the life you want, and narrows a wide field down to two to four specific directions. Each comes with an honest read on capital required, time to revenue and risk level, so you have something concrete to take into the stress-test.
Is there a free tool to validate a business idea in South Africa?
Yes. The discovery and stress-test tools are both free to use, with no account required until you want to save a result. Alongside them, the break-even calculator and the runway calculator let you check the underlying numbers on any idea, including ones you are testing outside this process entirely.
How long does the evaluation take?
The discovery conversation runs fifteen to twenty minutes. The stress-test takes longer, generally thirty to forty-five minutes, because it asks for real numbers rather than guesses. Both can be paused and picked up again once you have an account.
