What it does
Two ways to use dupay. As a validator: post an idea, real people price it in one tap, no account needed. $0 is a valid answer with its own leaderboard tab next to the ideas people would actually pay for. Become a Builder: claim an idea that priced well and inherit everyone who said yes. You start day 0 with real people ready to buy, not a blank inbox. Most tools tell you if an idea is good. dupay gives you the people who already agreed.
A market where people say what they would actually pay for products nobody has built. Not likes — declared willingness to pay, in euros and dollars, on ideas before they exist.
Name a price on something nobody has built yet. No account needed.

- ASA site to help you validate ideas in bulk2020 · ▲93
Hi HN! I made a really quick web app to help people validate their ideas. The app is a simple landing page builder, but every page includes a really simple Yes/No "Are You Interested?" poll. Every vote is recorded and tracked, and if they click yes they are brought to a page where they can submit an email. This makes validating ideas super easy because you can post your link to different communities and get statistically significant results as well as build an email list. Given an hour, you could easily create 50 different landing pages and be able to validate your ideas in bulk. The…
- WCWillpayforthis.com – Ideas people will pay for2025 · willpayforthis.com · ▲41
Ah, there's a dumb easy hack to figure out what ideas people will pay for. Search "I'd pay for" on Twitter and you'll find hundreds of posts from people talking about pain points and products they'd pay for to solve them. Do this enough and you realize you have to filter through a lot of slop. slop. slop. I created willpayforthis.com to accumulate high signal, high quality posts and save you some time. I love thoughts from the community on how I can make it better, save you time, and help you work on the best ideas.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
