Products that do what Bookface for Non-YC Founders does
Excited to announce my new project, Rally! It’s a useful community for early-stage startup founders, inspired by Y Combinator’s Bookface. Site: https://rally.socap.ai/ We think many problems that founders have can be solved 10x better through other founders, but there’s no tool/place to do that well and at scale. For example, instead of googling how to launch on PH, reading blog posts, etc., you could ask for an intro to a famous hunter who’ll explain all that and hunt your product. We're building this place + software to make it work really well. What Rally is: • A…

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…

Hey Everybody! Hope you had a merry christmas Today I had a bit of fun with Claude. Started by scraping YC's startups list, then ran them through OpenAI's embedding service, then UMAP'd the embedding to reduce the dimension to just two coordinates and then just forced Claude to write React that would compile to visualize that. I had fun and I think it's interesting, so take a look! Also note that you won't be able to zoom on mobile (found about this Plotly limitation way too late). If there's interest I can fix this issue by changing plotting libs tomorrow :) Merry christmas

Got rejected from YC a few times, so I built a site to collect lessons, reflections, and what people would do differently next time. Thought it could be helpful since most founders apply more than once anyway :) Hope it's helpful: https://ycrejection.com/

So a while ago I was thinking it would be neat to build a site that had the most absolute utility. The idea I came up with was a site to store those little protips that are super useful, if you know them ahead of time. I hired a guy to work on it with me, and ClueDB was born: http://cluedb.com/ Please give it a whirl (it uses Twitter auth as login but doesn't tweet anything) and tell me what you think! (Various trivia: My first try at a project coded by someone else and "product managed" by me. Runs on Flask + MongoDB. Also, this is totally unrelated to my startup.)

Hey, just wanted to share with you guys and app that I built and deployed in a day with Lovable. So, as a founder I always wanted to have an advisor but my budget would always be less, then on the other hand hand I had Paul's essays on Startup Advice, which I never read because I was busy building stuff. Hence, I built this product which comes into a sweet spot of both at the same time being more reasonable and capable than the alternative. ps: it's running on a reasoning model and tbh I've been able to gather pretty good insights from it. Note to PG: If you're seeing this. I'm your big fan.…

Hey everyone! We spent the major part of the year preparing an idea we had for the YC application. At last minute, we decided not to go through with YC. I mean, we've had our fair shares of failed startups and this was one of those make it or break it scenarios. We took everything we've ever learned and strived to make an app that we were proud of. We spent so much effort into making this app that we couldn't bear stopping short and applying to Y Combinator. (Mind you, there's nothing wrong with YC.) We didn't want to apply to Y Combinator at the last minute because if we had really gone…

I am announcing the private beta of my first web app (http://getfounder.com). The beta will launch in just one city, which will be determined by the number of entries on the location-aware sign up page. As this is my first public release, I'm looking to the HN community to offer me feedback on what I should/shouldn't be displaying on the homepage. I'd be grateful for any advice you had to offer. Thanks, and I hope to see some of you in the private beta! Colin

I'm a Computer Science student who loves creating things. Even though university is tough, I always make time for personal projects. Yesterday, I launched my first website that aims to help startup founders find their ideal team members and, at the same time, assist individuals in joining projects that align with their skills and interests. There are also a ranking of the most popular startups and some filters you can use to search what you are looking fot

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 built this using investor tools. I really wanted to know which startups to work for. Are we on the right track? PS - there's a paywall but if you want to explore more, just DM me your email and I'll give you free access in our db!

website: dashboard.io I've been thinking about this idea for a while now and finally got around to building the prototype this weekend. The idea is that you'd drop my JS snippet on your site and I'd start building the "AARRR" table (which I'm actually building this week but imagine slide 4: http://www.slideshare.net/dmc500hats/startup-metrics-for-pirates-long-version). Basically, the system will build that table out for you and then show you how your startup stacks up against others in your space. To be clear, I'll never share your data with anyone. So, if you're a "hosting" company, I'd…

We hatched this idea of a Kickstarter + Groupon + Etsy model last week, threw up a super simple landing page that day, then launched a more detailed landing page last night. What do you think of the idea as a whole? The landing page itself? Since the Etsy / crafting world is so large and diverse, we're really trying to focus on the sharing of our site to get the word out. We are doing some minimal google ads and will be doing various tests to see what brings in the best traffic and converts the best. Interestingly enough, good old fashioned twitter searching with hand authored tweets has had…

Hey HN, I built this tool that maps out every YC company worldwide. You can zoom into cities, explore clusters, and click to see details like batch, location, and website. Why I made it? I thought it’d be fun to visualise it, using the same infrastructure I already use in my other project: FoundersAround Some things I’m still improving: • Improve performance • More filters (industries, stages, etc). Would love your feedback. https://yc.foundersaround.com

Hey HN, I'm Aydin, a 13-year-old developer and indie maker looking to improve the world with my small startups. Recently, I built 2 micro SaaS projects. I spent days & weeks coding features, always telling myself that after coding one more feature I was for sure to get traction. This never happened. The reason: I never launched. With IndieReq, you can launch your startup fast and get real user feedback so you know exactly what features to ship and improve. All you have to do is sign up for free, create a feedback board, and share the public link with your users. It's that easy! If you've…

Hi guys I know ur time is valuable so I will keep this short. Ever since I was in uni I saw that its been difficult for people finding collaborators for your project/startup. Building something is easier than ever but finding collaborators has never been more difficult. so I interviewed 1083 users (yea i know thats a lot but i needed some validation hehe). Half of them did not hear about yc cofounder matching and other platforms and the ones who were using them still found it quite painful and exhausting and they got no one from there. I found that in most cases for my users the only…

I created this tool, RantGPT, to let you share ideas with gpt-4o and connet with others who have similar thoughts. I made it to help us find cofounders and soul mates more easily, but you can share anything and see if anyone else has thought something similar. Please let me know what you think!?

Hello HN! I'm excited to share my product that helps companies to track their competitors, their website updates, new features, social media activity etc. I already have the first set of early adopters (thanks to a pretty good ProductHunt launch) who're using it on the daily basis so I'm excited to remove the waiting list and share it with everyone. Cheers!
