It started out when I thought about how to help founder to validate their idea, not just coming up one but how to turn the idea into real business by not relying on AI but making them more involved into their product, understand the market by doing research, check what user want. It's like a checklist, a step for someone who want to get start. This is not an AI to go tool, it's a tool to drag user back to reality, simple but important. I don't think I'm gonna make money with it so I decide it will be a free to use. Use referral code "beyondzero" to sign up. Thanks

Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years. Fast forward to now. I'm a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It's basically…

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 :)

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/

Hi Guys, I got overwhelming support and feedback from my last post about secondfounder.com but still, I felt the need of connecting founders together so that they can together buy a side project. It's very often when a non-technical founder buys a project they have to find a technical founder to take that project further. Today I have implemented this feature in secondfounder.com Link: https://secondfounder.com/find-founder Your feedback is always welcome. Thanks

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…

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/

Foundera▲30Most 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…

We built this database using the same software investors use to discover startups. My friends and I really wanted to know which startups to work for. Are we on the right track? PS - there's a paywall but if you want to explore more, just DM me your email and I'll send you a free access code! Thank you so much.

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.…

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.

Howdy friends. I've been a zero to one product manager for 12 plus years and along the way I kept borrowing pieces from different discovery frameworks until I had a methodology of my own, one that actually raises the odds of an idea succeeding. This does not replace user interviews obviously, but it leads you in the right direction. Looking forward for your feedback

Hey HN, I’m 14 and I’ve been obsessed with startups for a while. I noticed one big problem: most of us (especially first-time founders) waste months building something that nobody wants. So I built Startup Solve — an AI-powered platform that helps you stress-test your startup ideas before you write a single line of code. It includes six tools: ~ AI Co-Founder → brainstorms with you like a smart partner. ~ Startup Oracle → pressure-tests your idea and asks the brutal questions VCs would. ~ Funding Predictor → gives an estimate of whether your idea could raise funding. ~ Idea Incubator → helps…

orignally shared this on startup school... i thought id' share it here. i'm using a `nocode communication tool` (a web-based interface... a single browser tab!) for all of these things: 1. landing page — the landing page is the product and i wanted for folks to feel "transported" right into the app without having to walk through a shitty b2b marketing-style content. this is akin to my experience back in the `BBS` days of the mid-90's where you were immediately into the app, community, and tool. no terms of service, no privacy policy. just pure, immediate value. 2. building community — we…

I am working on this because I am always afraid of building things that people don't actually want. I let agents role-play analysis the idea, quote and debate with each other. Still working on the output quality, every feedback is priceless. Pls try it out!

We've just (re-)launched Arta Labs! Join our subreddit for a give-to-get feedback system. Before you can post your idea, you must review 4 other ones first. This provides a better incentive structure than the take-take environments many other forums tend to be. Additionally, we have also set up a private community for aspiring or existing entrepreneurs working on ideas, big or small, to build alongside each other. We organise co-working days, private group chat, a knowledge lab, are also building a mentor network where members can book 1-1 calls with experts. Find out more at…
