ShliffPrediction over gut feeling
Ask someone who spent six months on an idea when they realised it wouldn't work. The answer is almost always the same: somewhere around month four. Not on a particular day, not because of a number. It slowly dawned on them.
That is the most expensive way to find something out.
A gut feeling can't be wrong
The reason isn't laziness or sloppiness. The reason is that a gut feeling can't be refuted. "I think there's a market for this" can never be tested — it can only be felt more or less strongly. And because it can't be refuted, it survives every setback. The landing page barely gets sign-ups? Wrong channel. No one replies to the messages? Wrong wording. There is always an explanation that leaves the original hunch untouched.
A hunch that survives everything never told you anything.
The difference is a number and a date
Compare two sentences:
I think solo developers would pay for saved time.
If I put up a landing page within seven days and post about it in two specialist forums, at least 30 people will join the waiting list.
The first sentence can't be wrong. The second one can — and that's exactly what makes it worth something. On day eight there is a number, and the number doesn't belong to you. If it's six instead of thirty, you didn't "pick the wrong channel". You were off by a factor of five, and that is information other people pay for in months.
Three things make the second sentence usable:
- A number. Not "many", not "enough" — thirty.
- A deadline. Without one, the test slides into the indefinite future, and always voluntarily.
- A way to get the number. Without it, the deadline is just a reminder. Anyone who doesn't know how to measure won't measure.
The third point is the one most often skipped. "We should validate this at some point" sits in a lot of notes and rarely turns into anything. "One-page landing page, one hour, plus two forum posts, thirty minutes — count the sign-ups" gets done.
Write the number down before, not after
The most important part is the order. The threshold has to be fixed before the measurement.
That sounds pedantic, but it's the whole trick. If you set the line only after you know the result, the line moves. Six sign-ups suddenly become "a first indication of interest" — and the path you actually wanted to leave carries on. If the thirty is written down beforehand, that excuse is gone. You can still decide otherwise, but you have to do it deliberately.
That's why the prediction includes the second half of the sentence too: the number at which you keep going — and below which you stop.
Refuted isn't failed
The biggest hurdle is emotional. Writing down an assumption that can fall over feels like a risk. In reality it's the opposite: the risk lies in not doing it and putting six months into something that would have been refuted after four weeks.
A refuted assumption doesn't mean the idea is dead. The whole idea is almost never wrong — one particular assumption inside it is. "Instagram brings 200 visitors a week" can fall over without touching "clubs book catering". Afterwards you know more than before, and you know it after a week instead of half a year.
Testing them one at a time isn't a compromise, it's the point: if the riskiest one falls over, you've saved yourself all the others.
What stays uncomfortable
To be honest: this way of working makes an idea less pleasant to work on. As long as nothing is measured, every idea is still the good one. A number with a date takes that state away from you — faster than you'd like.
In return you get something a gut feeling never gives you: a reason why you're continuing. Not "I believe in it", but "I expected thirty and got forty-two". That still holds up in month four.
How Shliff helps
That's exactly what the hurdle loop in Shliff is built for. You take on one assumption, and the AI first gives you research tasks — what to find out in the real world, in forums and communities, with concrete sources to start from. Not what you already suspect anyway.
What you find becomes the assumption to test. Then you set a number and a deadline and get a concrete suggestion for reaching that number within a few days and without a budget. When the deadline passes, the app asks — extend with a reason, or drop it. Quietly running on isn't an option.
At the end there is no score you can talk your way around, just the comparison: estimated thirty, measured six.
