Products that do what I built a game where you guess which startup idea succeeded does

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!

    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…

    Hey my name is Ivo and I'm a developer and a startup entusiast. My girlfriend was out of the coutry for the weekend and I decided to do something cool like building a startup. I've done a few startups over the years but that's the first I actually released, I would love to hear your feedback on it.

    I’m a non-technical idea guy and a business guy that has been successful in my work for other startups. As someone who has been a founding employee at more than one startup, I’ve gotten to a point where I am sitting on ideas I think are brilliant and would love to build. I’ve noticed how difficult it is to find a technical co-founder, let alone convince them to come on board with an idea. That turned into a project for me, learn to build something myself. So I built a site that is meant to help idea/marketing guys connect with technical co-founders and vice versa.…

    Hey all, I’ve always believed that starting a business should be easier. The brainstorming, the research, the branding—it’s exciting, but it can also be overwhelming. I wanted a tool that could take an idea and fast-track it into reality. So, I built it. StarterPilot. An AI-powered platform designed to help entrepreneurs go from “what if?” to “let’s launch” in record time. But here’s the crazy part—I used my own tool to build my startup. I started with my idea—an AI-driven assistant that could validate business concepts. Within seconds, StarterPilot analyzed market demand, revenue potential,…

    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…

    Hello HN, Later today I'll be shutting down the servers and moving on. This is my 5th startup and the 4th failure. The reason is very simple: I understimated the cost of user acquisition. This is the second time this happened. The dozens of users actually love the software and are using it on a daily basis. I'm ruthless when it comes to coding and money. So, if you are building a startup: do not ignore how much money you will have to spend to get a user. If you are not able to find that number, something could be wrong with your model. Maybe someone smarter than me could write something…

    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…
