Buildpad▲543Hello people of Hacker News, I’m Felix and I’ve spent the last few months building Buildpad together with my brother David. About two and a half months ago we launched Buildpad on Product Hunt and got a very positive response. Since then we’ve been constantly improving the product and grown to over 2,400 founders using the platform and 70 active paying customers. - If you’re a founder who’s wasted time building products no one wants, then Buildpad might be for you. Buildpad is an AI-guided product building platform that helps founders build products people actually want. Buildpad guides you…

BrainGrid▲26Hi HN, I’m Nico, one of the co-founders of BrainGrid. We built this after spending the last year building software almost entirely with AI coding tools like Claude Code and Cursor. Writing code was fast. Finishing anything reliably was not. Coding was not the bottleneck. planning was. It was everything before the code: unclear scope, missing edge cases, poor sequencing, and vague intent. Once a project went beyond a single prompt, small changes started breaking unrelated parts of the app. In traditional teams, product managers and tech leads handle this. I was a Director of Product at Twilio…

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

FoundersWall▲35I used to be just a blogger. Now I build internet products, still without code, using AI, design, and taste. I was building in public on X for last 2 months. And honestly, I got tired of how it became performative and started to feel fake. I shipped 2 products. Both failed to get any real traction. I kept sneaking into popular builders’ profiles, hoping to learn how they do it. One thing I kept seeing everywhere, product launch directories. I thought here is the scope. So I started building one. Same UI like the rest. Nothing special. Suddenly one day when it was half built, I realized…

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…

I'm a solo indiehacker and just made Makeform AI — an AI form-building copilot that lets you build complex forms by chatting, kind of like how Cursor helps you code. Instead of dragging and dropping fields or wrestling with logic conditions, you just tell Makeform what you need, and it generates everything: Questions Conditional logic Design Integrations (email, Slack, webhooks, etc.) For example, say “I need a lead-gen form for B2B SaaS founders” — it’ll generate a beautiful, branded form, ready to publish or embed. Why I built it: I’ve always found traditional form builders slow and…

I built a tool to solve a problem I kept running into: I was making product decisions based on guessing instead of real users. I kept building stuff nobody wanted as I was usually wrong. So, I built HolyShift: AI agents that validate product ideas by talking to real people on Reddit, HN, X, and LinkedIn … then generate a detailed GTM and “Should we build this?” report. No synthetic data (ChatGPT). No predictions. Only real conversations from real people. What it does • Posts platform-native questions (where allowed) • Collects real reactions, objections, pricing signals • Clusters feedback…
