I’m stuck on what to build next for Crazy Sajangnim
I’ve been building Crazy Sajangnim, a community-based fashion shopping platform focused on the moment between “I found this” and “should I actually buy it?”The original idea started with discovering discounted fashion, but over time I’ve been trying to make the community side much more important. Instead of just browsing products, users can share finds, ask for opinions, talk about fit, quality, styling, price, and whether something is actually worth buying.At this point, though, I’m a little stuck.The basic product works, and I have a clearer idea of what makes it different from a normal shopping site, but I’m not sure what the next meaningful feature should be. I don’t want to keep adding features just for the sake of making the product look bigger.Some ideas I’ve considered are better co-shopping tools, voting or “buy / skip” reactions, shared shopping lists, stronger user profiles, price tracking, product comparison, more detailed discussion around items, and ways to bring products in from any shopping website.But I’m not sure which of these would actually make people come back regularly.So I’d really appreciate suggestions from other founders and shoppers:If you were using Crazy Sajangnim, what would you want me to add next?Especially curious about:What would make the community genuinely useful rather than just another comment section?What would make you post a product and ask other people for opinions?What feature would make you come back every week?Is there anything I should actually remove or simplify instead of adding more?I’m at the stage where outside perspective would probably be more useful than another week of me brainstorming features alone.
I’m intentionally making Crazy Sajangnim show you less
A lot of shopping products are built around the same idea: more products, more stores, more recommendations, more things to scroll through.While building Crazy Sajangnim, I’ve started thinking in almost the opposite direction.One of the constraints I gave myself from the beginning was that the shopping side should focus on items that are actually on sale. Not a giant designer-fashion catalog where you have to dig through hundreds of full-price products before finding something interesting.That sounds like a small product decision, but it has affected almost everything I’m building.Crazy Sajangnim currently brings together discounted designer fashion from Korean and U.S. retailers and lets you narrow it down by market, brand, and category. The goal isn’t to become another endless fashion marketplace. I want opening the site to feel more like:“What is actually worth looking at today?”I’m a fashion enthusiast myself, and I realized that when I check multiple stores, I’m rarely browsing every product they carry. I’m usually looking for the interesting overlap between:a brand I already like + a meaningful discount + something I would genuinely consider wearing.So instead of optimizing for the size of the catalog, I’ve been thinking more about the signal-to-noise ratio.The social side of Crazy Sajangnim fits into that idea too. Once you find something interesting, the next problem isn’t discovery anymore. It’s deciding whether it deserves your money.That’s where the community comes in: sharing a find, asking what other people think, talking about styling or fit, and occasionally having someone tell you, “No. Do not spend $600 on that.” 😂There are still a lot of things I want to improve, especially around how products are collected, how quickly new sales appear, and how useful the browsing experience feels as the number of supported brands grows.But one product principle I’m becoming increasingly convinced about is:A shopping platform doesn’t necessarily become more useful by giving people more things to buy. Sometimes the better product is the one that removes everything that isn’t worth considering.That’s the direction I’m experimenting with for Crazy Sajangnim.If you shop online often, I’d be curious about one thing:Would you rather use a fashion site with a massive catalog, or a much smaller feed that aggressively filters for things that are actually worth checking out?https://saashive.com/view-product/8fc6144e-8f3c-40b0-87d2-a788f8af885a
I’m looking for honest feedback on Crazy Sajangnim 👀
Hi SaaS Hive! I’m continuing to build Crazy Sajangnim, a fashion discovery and co-shopping platform focused on discounted designer fashion from Korean and U.S. retailers.The idea started from a problem I kept having myself: finding something I liked was easy, but deciding whether I should actually buy it was much harder. Is the price really good? Is there a better deal somewhere else? Will I actually wear it? Is the quality worth it?Crazy Sajangnim is my attempt to make that decision more social. You can browse sale items by brand, market, and category, then use the community blog to share finds, ask “should I buy this?”, discuss fit and styling, and get opinions from other people who genuinely enjoy fashion.I’m still early, so honest feedback would be extremely useful right now. If you have a few minutes to try it, I’d especially love to know:Is it immediately clear what Crazy Sajangnim is for?Does browsing the sale products feel useful or overwhelming?Would you actually use the community/blog before buying something expensive?What would make you come back regularly instead of visiting once?Is there anything confusing, unnecessary, or missing?At what point, if any, do you feel like leaving the site?You can sign in quickly with Google and try the community features as wellPlease don’t worry about being overly positive. At this stage, hearing “I wouldn’t use this because…” is probably more valuable to me than hearing that everything looks good.If you test it, I’d really appreciate hearing what stood out to you and what you think I should improve next.https://saashive.com/founder-community/request-feedback/afe23890-c84f-437a-b4d5-25d72a704777
Shopping online is better when someone can talk you out of it
I built Crazy Sajangnim because finding a great sale is only half the experience. Sometimes you also need someone to say, “Buy it,” “Wait for a better price,” or “You already own something exactly like that.”Crazy Sajangnim brings designer fashion sales from Korean and U.S. retailers into one place, then adds a community blog where shoppers can share finds, discuss purchases, exchange styling ideas, and recreate the feeling of shopping with friends online.I’d love for you to try the actual experience:👉saashive.com/products/crazy-sajangnimSign in with Google, browse the sale listings, and explore the community features. Then tell me honestly:What made you hesitate before signing up?Was anything confusing after you entered?Where did you lose interest or feel stuck?What would make you return?Comments, candid feedback, and upvotes are much appreciated—they help me understand what to improve and introduce Crazy Sajangnim to more shoppers. Thank you!
Please try Crazy Sajangnim—and tell me where you stop
Hi everyone! I’m looking for honest, experience-based feedback on Crazy Sajangnim, my fashion-sale discovery and co-shopping platform.Rather than reviewing the idea from the description alone, I would really appreciate it if you could visit the website, try signing in with Google, browse the sale listings, and explore the community blog:saashive.com/products/crazy-sajangnimPlease be direct about anything that makes you hesitate, become confused, or leave. In particular:What, if anything, blocks you from signing up?After signing in, is it clear what you should do first?At what point would you stop using the website, and why?What would need to change for you to return or recommend it?Feedback about trust, Google sign-in, navigation, product selection, loading speed, mobile usability, or the co-shopping experience is all welcome. Even a short comment such as “I stopped on this page because…” would be genuinely useful.I’m especially interested in discovering the friction I may no longer notice as the person who built the product. Thank you to anyone willing to test it and share an honest reaction!
How I envied art to becoming a CS student
Hi, Hive! How is everyone doing?I’m the developer and founder of Crazy Sajangnim, a Korean-American fashion community:https://saashive.com/products/crazy-sajangnimI’m a Computer Science student at Boston University, and I’m currently working as a software engineering intern at a Korean startup. Working a traditional 9-to-6 job in Korea is a completely new experience for me, and I’m glad to have this opportunity—even though the heat and humidity are killing me right now!I used to love drawing and making art because of the freedom to be creative. Most of all, the idea that I could create anything I imagined felt empowering. I eventually became a Computer Science student, which might seem far removed from art—but I’m no longer sure that it is.What I loved most about art was the ability to create whatever I wanted. Software development gives me a similar freedom: I can build the tools and experiences I wish existed.That idea led me to create Crazy Sajangnim, a fashion shopping and community platform. The name comes from the Korean phrase “사장님이 미쳤어요,” which roughly means “The boss has gone crazy.” It is commonly used to describe discounts so large that the prices seem unbelievable.Building Crazy Sajangnim has allowed me to combine creativity with technical skills, so in a way, it feels like another form of art. Even though I did not become an artist, creativity is still an important part of my work as a software engineer. The things we build through code can be meaningful and inspiring, just like art.Come visit Crazy Sajangnim and use the blog to share your thoughts about fashion, creativity, or life in general!

How I went from my friends request to a full-on website
Hey everyone! I’m the developer and founder of Crazy Sajangnim, a Korean-American fashion community:https://saashive.com/products/crazy-sajangnimI’m a student at Boston University, and I have a friend with whom I’m always discussing fashion. In Korea, we have Naver Cafes—online communities where people gather to discuss shared interests. My friend and I actually became friends because we belonged to the same fashion community.We enjoy shopping together and talking about fashion, which gave me an idea: What if I combined online shopping with a community?My friend also asked me to build a website where he could browse only sale items from his favorite brands. I built it, but I felt that it needed something more. I added a “Share to Blog” button to every product listing. When someone clicks it, they are taken to the blog, where they can create a post about the item they selected.It makes what my friend and I already do much simpler. We used to send each other product links through Instagram DMs. Now, we can share an item with one click and receive feedback through comments and likes.The blog is not limited to products listed on the website. Members can also upload their own photos and use it like a regular fashion community—sharing outfits, styling ideas, shopping finds, reviews, or anything else they would like to discuss.I would really love to grow this community. Please join the blog and share your thoughts on fashion—or anything else that interests you! I’m very active in the community and will personally engage with your posts.Come visit Crazy Sajangnim and experience online co-shopping with us:https://saashive.com/products/crazy-sajangnim (Upvotes are very appreciated😊)
A Korean-American CS Student Building a Different Kind of Fashion Platform
Hi everyone! I’m Jinny 👋I’m a Korean-American Computer Science student at Boston University, currently working as a Software Engineer at EXTORY in Seoul. I spend most of my time building products, working on frontend and admin systems, experimenting with AI-powered developer tools, and learning as much as I can about what makes people actually want to use a product.Outside of software, one of my biggest interests has always been fashion. I love discovering designer brands, comparing prices between Korea and the U.S., finding pieces on sale, looking at how other people style things, and having those very serious conversations with friends that start with:“Should I buy this?”That interest eventually turned into a project of my own: Crazy Sajangnim.Crazy Sajangnim is a fashion shopping platform I built around discounted designer fashion from Korean and U.S. retailers. The name comes from the Korean phrase “사장님이 미쳤어요”, which roughly means “The boss has gone crazy” and is often used when a store is running a huge sale.But I didn’t want to build another website that just shows products and sends people to checkout.One of my favorite parts of shopping is the social side of it: sending clothes to friends, asking for opinions, talking about fit, sharing styling ideas, and helping each other decide whether something is actually worth buying.So Crazy Sajangnim also has a community blog where shoppers can share finds, outfit photos, reviews, styling ideas, fit notes, and “Should I buy this?” posts. My goal is to make online shopping feel a little more like shopping with other people instead of endlessly scrolling alone.I’m still very much in the building and learning stage, and that’s one of the reasons I joined SaaS Hive. I’m interested in meeting other founders, seeing how people approach distribution and product development, getting thoughtful feedback, and learning from people who are also figuring things out as they build.I’m especially interested in software engineering, AI products, fashion tech, online communities, consumer products, and the strange process of turning an idea you personally want into something other people might want too.If you’re building something, especially in consumer, community, AI, or e-commerce, I’d love to hear about it.And if you love fashion, you should definitely come say hi. 🙂saashive.com/products/crazy-sajangnim
I’m building the place I wish existed between “I found it” and “I bought it.”
Finding clothes online is actually the easy part.The harder part is everything that happens after:“Is this actually a good price?”“Does anyone know how this fits?”“Would I still wear this six months from now?”“Is there a better version somewhere else?”“Should I buy it before it sells out?”Most shopping sites are designed to get you from product page → checkout as quickly as possible.But that’s not really how people make fashion decisions.When I shop with friends, we send screenshots, compare prices, argue about whether something is worth it, talk about sizing, and sometimes convince each other not to buy something.That last part is important.So with Crazy Sajangnim, I’m experimenting with a different kind of shopping experience.The platform brings together discounted designer fashion from Korean and U.S. retailers, but the part I’m most interested in building is what happens around the product.You can discover something on sale, then bring that item into a community where other shoppers can react to it, discuss it, share styling ideas, talk about fit, or simply answer:“Would you buy this?”I don’t want Crazy Sajangnim to become another endless catalog.I want it to feel more like walking through stores with people who are just as obsessed with clothes as you are.There’s also something slightly funny about building a platform whose name basically comes from the Korean phrase “사장님이 미쳤어요” — “The boss has gone crazy.”It’s the phrase you see when a store is advertising prices so low that apparently the owner has lost their mind.So the name started as a joke about discounts.But the product is slowly becoming an experiment in something bigger:Can online shopping feel social without becoming another social network?Crazy Sajangnim is still early, and I’m actively figuring that out.If you shop designer fashion online, I’d especially love to know:Would seeing other shoppers’ opinions actually change whether you buy something?Or do you still prefer to make that decision alone?saashive.com/products/crazy-sajangnim
