What it does
BuildSignal hands you a fully-researched startup opportunity every day. Each is a 15-section brief — real Reddit pain, who's paying for bad alternatives, where incumbents are failing, TAM, build estimate, and an honest BUILD or SKIP. 90+ live. Every quote sourced and cited.
Deep opportunity briefs for founders who've built before. 15 sections of real validation — Reddit quotes, WTP signals, competitive gaps, build estimates, and honest GO/NO-GO verdicts. 90+ briefs live, a new one added every day.
Daily startup ideas. Each one a full 15-section brief — who's in pain, what they're paying for, who's failing them, and exactly what you'd build to win. One-time $99. Lifetime access. We're moving to a monthly subscription soon — lock it in before we do. “I spent 3 weeks validating an idea last year. This brief had more signal in 15 sections than everything I gathered on my own.” A new validated opportunity added every day. Each one: real user pain, real quotes, real WTP signals, and our honest GO/NO GO. Every quote sourced. Every data point cited. Every URL verified. Every brief ends with a verdict: BUILD or SKIP. We don't hedge. We deep-dive G2 reviews for every niche — not the 5-star…from buildsignal.today

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…
Don't Build Things No One Wants!Oct 2025 · artalabs.com · ▲8We'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…

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
