Don't Build Things No One Wants!
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…

What it does
Validation Lab | Many founders waste months building something only to discover no one wants it. We help you validate ideas first so you can find out if real users care in weeks. Is your idea worth building? Let’s prove it together with a validation sprint.
Arta Labs is a community for people working on startups and ideas, big or small, who want to build alongside others. Check out our subreddit, r/ArtaLabs or join our exclusive members community for mentorship, co-working and more.
If most people around you aren't building anything, that shapes what feels normal. Arta Labs' Coworkathons change that. We run dedicated coworking days to bring those working on projects of all kinds together, in-person, to work alongside other productive people. Just bring yourself and something to do, stay as long as you want. It's low pressure, networking is organic, not forced. Arta Labs is a community for existing or aspiring entrepreneurs, creatives, freelancers, researchers or just anyone seeking to work, build, grow and learn alongside others. If you usually work from home especially, come try a coworkathon! Arta Labs is part of a Community Interest Company. To support us, consider…from artalabs.com

FounderaJul 2026 · foundera.app · ▲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…
- PTPlace to support and validate early startup ideas2022 · ideas.dynamate.io · ▲52
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…
FoundersWall2025 · founderswall.com · ▲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…
a community for collaborating on sideprojects2025 · relentlessly.no · ▲48TLDR: I made a community where you can find builders or product owners to collab on sideprojects together with <3 A year ago i completed my first sideproject, a digital course on how to "cold email a chief information security officer". I thought and think its a great course, but of course I fell into all the traps (didnt verify a need, i thought id make it and everyone would buy automatically), i tested google ads but hated nerding on that, so i decided to find a marketing person to partner up with! But i knew no one! That got me thinking how many people with relevant knowledge that isnt…
- IAI accidentally built a startup idea validation tool2025 · validationly.com · ▲15
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/
- IMI made a tool to help collect and validate startup ideas2024 · keepmyidea.app · ▲38
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 went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
