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.

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/

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…
