24 alternatives to Share your startup Idea, find others working on it
I created this tool, RantGPT, to let you share ideas with gpt-4o and connet with others who have similar thoughts. I made it to help us find cofounders and soul mates more easily, but you can share anything and see if anyone else has thought something similar. Please let me know what you think!?

A few days ago, I responded to a comment by bloggergirl offering to read anyone's web copy and help. I shot off an email hoping for a paragraph or two of feedback on my startup's copy. Instead I received a professional, detailed deck of tons of invaluable well thought out feedback. It must have taken her an entire afternoon. Here's a link to it: http://www.slideshare.net/shereefb/recommendations-for-bettermeans To top it off, this isn't someone with a lot of free time on her hands, she's only days away from launching her own startup (page99test) This community blows my mind!

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/

I wanted to find a product idea to build. "Build things people want," right? So I thought, why not literally find people saying what they want? I wrote a script to collect thousands of Reddit posts where people are looking for a solution or complaining about a problem. Then I used GPT to filter out the noise and score each one based on how viable the idea seemed. Threw together a simple search interface so anyone can explore them. I was planning to build a more advanced paid version of this, but figured I'd share the raw version first to see if it's actually useful to anyone.

I am announcing the private beta of my first web app (http://getfounder.com). The beta will launch in just one city, which will be determined by the number of entries on the location-aware sign up page. As this is my first public release, I'm looking to the HN community to offer me feedback on what I should/shouldn't be displaying on the homepage. I'd be grateful for any advice you had to offer. Thanks, and I hope to see some of you in the private beta! Colin

I built a tool (https://1mil.app/hn) to help me test my intuition about various weird business ideas that were on my mind. Initially, I wanted to create a database with 1 million business ideas (hence the name - "1 million opportunities"). But turned out to be a dumb idea already. So instead I built this tool that returns only 10 ideas. It's all based on your input, market + your background. The first release scored on demand only and it gave false confidence. So I rebuilt the the scoring around "winnability": can a solo founder with a specific background "win" against what…

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…

Hi there, So a buddy a couple of days ago came up with the idea for a new SaaS product regarding gpt and image generation. We did a quick MVP that barely works, it breaks almost 50% of the time but we still wanted to validate the idea before going all in. We have almost 1k followers on Twitter together. Did a quick post describing the idea with a stripe link in the comments with a 5$ value, no landing page, and no shipped product. In exchange, the buyers become beta users. Around 30 mins later we got our first sale next 30 mins another 5$ and so on. Do we consider the idea validated? The…

I was frustrated with how I share ideas online. LinkedIn/X forces you to compress everything into hot takes. Research papers require months of work. And posting on social media increasingly feels like trying on outfits in ChatGPT until you find one that "fits" – performance over genuine thinking. I wanted something in between. A place where: - Half-formed ideas are okay - Thinking evolves over time (with revision history) - Garbage gets pruned naturally through format itself and status tracking (exploring → resolved → abandoned) So I built Kwegg. How it works: 1. You're in ChatGPT or…

So I've been obsessed with a weird question for the past 6 months, what happens to SEO when everyone starts asking ChatGPT for recommendations instead of Googling? The answer, apparently, is chaos. And maybe opportunity? I built FirstClick because I noticed something strange. My previous startup was getting zero traffic from AI assistants, but our competitor (objectively worse product, sorry not sorry) was getting mentioned by Claude and Perplexity constantly. It drove me crazy. So I reverse engineered why. Turns out there's a whole new game being played and most founders don't even know it…
