Buildstash▲168Hey HN! We just launched open sign up on Buildstash. It's a platform for managing and sharing software binaries. I'd worked across game dev, mobile apps, and agencies - and found every team had no real system for managing their built binaries. Often just dumped in a shared folder (if someone remembered!). No system for versioning, keeping track of who'd signed off what when, or what exact build had gone to a client, etc. Existing tools out there for managing build artifacts are really focused on package repository management. But miss all the other types of software not being deployed that…

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…

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…

Hi HN, I started a small newsletter to document what I’m learning while building projects — the decisions, mistakes, and experiments that usually stay behind the scenes. It’s not a growth hack or a polished media thing. Just short write-ups about what worked, what didn’t, and how I’m thinking through problems as I go. I’ve only published a couple of posts so far, but it’s grown to 1,000+ readers, which surprised me. Sharing here in case it’s useful to others who enjoy building in public or learning from real-world attempts rather than theory. Happy to hear feedback or ideas on what would be…
