24 alternatives to I built a game where you guess which startup idea succeeded
I’ve been studying real-world SaaS ideas — some that took off, others that failed hard. I turned it into a small side project: StartUp or Flop? You get two real startup ideas. One became successful, the other didn’t. You guess which is which, then you get the actual answer plus a short explanation of what made it work (or not). It’s a lightweight way to learn from real startup outcomes, uncover the patterns behind success and failure, sharpen your product instinct — and maybe even confront some of your own startup biases along the way. It’s surprising, humbling, and kind of addictive. Would…

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!

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…

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 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…

A little history first. Back in Jan 2011 I quit my day job after saving up my $ for a year and began my first startup, a hardware + SaaS business. It was exciting and at the end of 14 months I had a handful of customers but not enough incoming to keep me going so I went back into the workforce full time, running it on the side. Naturally my time is pretty limited. Users kept signing up and I had to constantly print and post them unique welcome forms, direct debit forms, post out monthly invoices etc, the list goes on. The paperwork alone took me hours. I'd have just coded up each form into a…

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!

Hey HN, I'm Aydin, a 13-year-old developer and indie maker looking to improve the world with my small startups. Recently, I built 2 micro SaaS projects. I spent days & weeks coding features, always telling myself that after coding one more feature I was for sure to get traction. This never happened. The reason: I never launched. With IndieReq, you can launch your startup fast and get real user feedback so you know exactly what features to ship and improve. All you have to do is sign up for free, create a feedback board, and share the public link with your users. It's that easy! If you've…

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.

It's called learnfrom.co, a platform for creating, hosting and selling online courses. I started building it because I wanted to solve a problem I had with existing course platforms. I kept running into things I wanted to change, so I started building them myself. The problem: I wasn't really a software engineer. Instead, I started using AI to build the product. I'd describe what I wanted, let it write the code, test it, fix things when they broke, and repeat. That somehow turned into a real product. LearnFrom is now used by 100+ creators and businesses, with real students and real payments…

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…
