How many interviews do I need for a reliable validation?
Often 8–15 targeted conversations are enough to reveal clear patterns. planix helps you ask the right questions and evaluate the answers in a structured way — instead of interpreting on gut feeling.
How does planix simulate the reactions of potential customers?
planix combines intelligent AI simulations with market and expert knowledge to simulate realistic reactions of potential customers to your business idea. This gives you a well-founded picture early on of how your offering is likely to be perceived — even before you run real interviews.
What if the feedback speaks against my idea?
That is exactly where planix delivers the most value: a clear no saves you a lot of money and months of work. Often it also shows that the idea isn't wrong — only the target group or the offering needs sharpening.
Do I need a finished product already?
No. You validate your offering before you build it. That is exactly what protects you from investing time and money in something the market doesn't want.
Can I trust the results?
planix shows you transparently which assumptions each assessment is based on — and clearly marks what you still need to verify. You get a clear framework, not a black-box output.
Does testing cost me anything?
You can start this phase for free — no credit card, no subscription. You see exactly what you get before paying anything.
