💡 Sorry Jesus, lord of AI, for I have sinned, but I’m tapping into the AI hype now. Yes, you read that correctly. I’ve made an AI tool that helps to get a sense of product-market fit.
🦄 It’s called PM-FIT GPT. 🦄
Rundown
Product-market fit is vague
Measuring it pre-product is hard
Still, you would like to get a sanity check if you are going in the right direction
Now, Product-Market Fit GPT gives you a 0-100 score and clear feedback
What you get: Overall score + Essential Fits
Feedback per essential building block
What do you need?
You need nine building blocks of product-market fit based on the logic below.
These are 9 simple questions to reveal simple answers.
If answered correctly, this gives a natural flow that makes it reasonable to believe that your product will be chosen for that problem over the competition.

PM-Fit GPT 🦄
I’ve built a custom GPT, trained on my articles about essential building blocks and on handwritten feedback about several startups’ PM‑Fit logic.
After a period of serious tweaking, it now delivers genuinely useful feedback when you enter your nine answers.
“No bullshit, just direct feedback to find your niche, and the real reasons customers would buy you”.
Example: an unfocused sustainability platform
Let’s run this poor, fictitious startup through it. They are building a platform for sustainable initiatives, but lack focus.
Customer Segment: SMEs wanting to save money
JTBD: Focus on energy transition
Problem: It’s hard and overwhelming
Dominant Competitor: A failed initiative with reporting
Competitor Flaw: But nobody used it
Consequence: Trouble with meeting demands
Solution: Luckily, we have an all-in-one platform
Feature → Root Problem: That is easy to use
Feature → Competitor: And integrates with SAP
Overall Score and core focal points
