⚖️ Startup idea validation

I love it. The data is really accurate and it points out things we didn’t even think about. It also correctly identifies competitors we didn’t even know existed.

1 Reply Share Delete Report

Thanks Pramima! Glad the competitor discovery hit the mark. That's exactly what I built for: surfacing things you'd miss doing it manually. Happy building!

⚖️ Startup idea validation

Game changer. Fast, reliable expert feedback without the awkward asks. Skip the friends and family bias , get real market insights in minutes.

1 Reply Share Delete Report

Thanks Nodus! "Skip the friends and family bias" is exactly why I built this. The data can hurt, but better to know now than 6 months into a dead end. Appreciate the review 🙏

⚖️ Startup idea validation

So I tested out Test Your Idea, and it actually works pretty well. You put in your idea, wait a minute, and it shows you the stuff you've been missing. Got some decent pivot suggestions that helped me refocus from a tiny niche to something way bigger. Saved me from probably wasting a few months in the wrong direction if you're actually gonna build something, not just daydreaming about it

Thanks Julio! That's exactly what the Niche Coach is built for. Glad it helped you spot the bigger opportunity before you went too deep. Good luck with the build 🤝

⚖️ Startup idea validation

On top of the large amount of the data that the tool provided, it helped me identify critical shortfalls in my idea, that I had not previously even thought about despite having developing my idea for a good while now. The tool also offered several suggestions on how to pivot my idea to increase the likelihood of success. For me, one of the suggestions required only a minor amount of work, but in turn allowed me to move from targeting a small niche to a large, proven customer base. This, for me, was the most valuable part of the report. I would recommend "TestYourIdea" for anyone serious about taking the step from an idea to an actual business. I feel like what I paid is incomparable to the potential hours and money saved by making the necessary changes now rather than later.

1 Reply Share Delete Report

Really appreciate the detailed feedback Larry. That "minor pivot, massive market" moment is exactly why I built this. Finding those blindspots early is worth way more than any report price. Excited to see where you take it 🚀

I paid the $3 for one analysis and have been waiting 3 days for it to complete the task. Don't waste your money.

Regardless of how you were notified, are you planning to fix the issue? It's still stuck at 68%. I will consider removing the review if I feel you're intent is truthful, or if the issue is resolved.

1 Reply Share Delete Report

The issue’s been sorted out and we’ve already refunded your payment. Your analysis is live now. Thanks for your patience — we’ll keep working hard to make sure this doesn’t happen again.

I enjoy how easy it is to validate your idea and after obtaining the results it pushes you to look at it from a different perspective. Also the design is admirable.
