Show HN: I accidentally built a startup idea validation tool

https://validationly.com/
14•kptbarbarossa•15h ago
I was working on validating some of my own project ideas. While trying to find how to validate my idea, I realized the process itself could be turned into a tool.

A few late nights later, I had something that takes any startup idea, fetches discussions, summarizes sentiment, and gives a quick “validation score.”

It’s very rough, but it works, and it’s already making me rethink a few of my own ideas.

It's still a work in progress. I don't actually know what I'm doing, but I know it's worth it. Honest feedback welcomed! Live demo here: https://validationly.com/

alberth•13h ago
Maybe dumb luck but I keep getting exactly the same “75” score - for each business idea I type in.

Like the idea though.

furyofantares•13h ago
My idea: extra stairs on staircases even when you don't need them because LLMS exist.

> 65, "good potenial"

> Model:Freemium SaaS

> Price:$29/month

> Break-even:18 months

> LTV/CAC:4.2x

> Projected MRR:$25K by Year 1

kptbarbarossa•5h ago
Thanks for try and feedback.
KaseKun•13h ago
I got a score of 25 for "What if everything was spiders?"
jkubicek•13h ago
I hit a score of 75 with $1b in realistic revenue for "racoonatooie"

kptbarbarossa•5h ago
:) Good luck on it.
harlanlewis•13h ago
I only got 65 for the same idea. I guess you have first mover advantage?
kptbarbarossa•5h ago
Wow, good try for a different perspective on idea validation.
kptbarbarossa•5h ago
Nice try :) thanks for another point of feedback.
kptbarbarossa•5h ago
I'm kind of stuck with the analysis system. I'm still working on it. The analysis methodology is currently based on prompt engineering.
3yanlis1bos•13h ago
I really liked all the info you have provided. You need a solid evidence to back some of the claims made by the system.

You might want to add a section where you list related/similar startups and how well they are doing (in terms of ARR and/or other metrics.)

kptbarbarossa•5h ago
I will consider this valuable feedback. Thank you.

Yet another "give me your business ideas for free" business tool ... now with AI wrapper!
kptbarbarossa•5h ago
I didn't actually set out to do this. I was working on projects but was wondering how to do validation. So I decided to develop my own validation tool. I'm still in development, but I believe it will be worth it.
jkubicek•13h ago
This tool thinks my intentionally dumb idea (Like Uber, except for beekeepers) has "good potential" with an obtainable market of $500mm/year within 5 years.
jkubicek•13h ago
My next idea wasn't as good. "boat stuff" is only a $12mm/year idea.
ojosilva•13h ago
yeah, the niceness and complacent nature of model training makes it hard to try to nuke any idea from all possible angles, which is what a good VC review does anyway. This a confirmation-bias validation tool!

OP, here are some pointers: prompt the model into the most negative, raunchy and insurmountable as possible personality. Give it examples in the system prompt on how VCs (or your average reddit user...) responds to business ideas, maybe as a different persona, then present negatives and positives from the model at different angles. Wash, rinse, iterate.

kptbarbarossa•5h ago
Thank you for your valuable feedback. I will consider it.

Entered the marketing text from the home page into the textbox ("Validate your idea before you build it. Get AI-driven market validation in seconds. Analyze demand across social platforms with actionable insights."), received a 75/100 score with a $10B TAM. I guess we'll see how valid this validator is soon enough.
wrayjustin•12h ago
Heh. I did the same. And got the same results (75/100).

Here's the Reddit copy it provided:
