    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/

    Hey HN, I’m Kyrylo. I recently created a small tool that lets you gather, refine, and validate SaaS/startup ideas using AI. I used to jot down my product ideas in a note apps, but it wasn’t very practical for collecting feedback or refining them. So, I built this tool to make the process easier. Here’s how it works: 1. Enter a brief description of your idea. 2. The app uses AI to generate project details. 3. Share your idea via a link that includes a feedback form. It’s pretty straightforward, and I’d love to hear your thoughts or any suggestions!

    I started a newsletter sending out daily startup ideas. After a year, I transitioned to weekly ideas with more in-depth details. I recently posted all of them to the website and made them searchable. Check it out and let me know what you think. By providing more than just an idea, my hope is to help someone start their next business. https://www.startupsfromthebottom.com/

    I made this for people like myself who keep a list of ideas for apps / startups. I also made it for people who are curious to see what projects others have "in their drawer"... and who may want to have a say in which idea should see the light of day. https://ideas.dynamate.io/ The site allows creators to anonymously showcase their idea: Title. Description text. Maybe some mockups... I've tried to make it so that it's quick and easy to just dump an idea in there that's been sitting on some list of yours for months - and hopefully get some feedback on it. If someone else on…

    Most people are not validating their ideas before start building it! I am a 5th time tech founder, gaming included and I built & managed startup accelerator programs. I know lot of things about early stage founders and their pains as I have been there. That is why I am building Foundera. It’s an AI-Native Accelerator for tech builders. Today the problem is; most of the AI coding tools opens with a chat and asking “type your idea and start building”. This is wrong! I want to reduce the time and money spent on ideas that nobody asked for. Try it at https://foundera.app and give me…

    hey y'all -- can you please tell us if our job search tool sucks? :D we built it using an investor platform called Harmonic.ai to gather startup data, then contextualize it so that job seekers could find out about the most exciting startups hiring first (like if they just raised, growing headcount fast, have an ex-unicorn founder, etc). pretty sure we're the first platform doing anything like this. anyway, let me know what you think. really excited to launch this thing soon! getting feedback from the hn community first is really fun :)

    I'm tired of seeing founders building stuff for months and years that nobody would ever pay for. They just don't see it, like most other founders learn to do. Business validation = making money, and nothing else really. If you really wanna make money this year, I can help you do it.

    Hey, just wanted to share with you guys and app that I built and deployed in a day with Lovable. So, as a founder I always wanted to have an advisor but my budget would always be less, then on the other hand hand I had Paul's essays on Startup Advice, which I never read because I was busy building stuff. Hence, I built this product which comes into a sweet spot of both at the same time being more reasonable and capable than the alternative. ps: it's running on a reasoning model and tbh I've been able to gather pretty good insights from it. Note to PG: If you're seeing this. I'm your big fan.…

    Hey HN, If you're like me, you have more startup ideas than free time, but turning those ideas into actual products often feels impossible. Coming up with a name, validating the idea, making a logo, and building even a basic landing page can take weeks of work...for just one idea. I built StarterPilot to fix that. It's an AI-powered tool that drastically shrinks the time from idea to launch, so you can test all your ideas, not just the one you bet the farm on. With StarterPilot you can: Validate ideas instantly: Get quick feedback on market demand, scalability, competitors, and risk.…
