Crazy Sajangnim
Fashion platforms with products and shareable community
Online fashion shopping is convenient, but I’ve always felt that something important was missing: the experience of shopping with other people.
When you shop with friends in person, you don’t just look at products. You ask questions like, “Would this look good on me?”, “Is this actually worth the price?”, or “How would you style this?” You compare options, exchange honest opinions, and stop each other from making questionable purchases.
Online, those conversations usually happen somewhere else. We browse products on retailer websites, search for fit information on forums, watch styling videos on social media, and message friends before deciding what to buy. The shopping and the community are separated.
That is why I created Crazy Sajangnim: a fashion-discovery platform that combines designer-sale shopping with a community for people who genuinely enjoy fashion.
The story behind the name comes from Korea.
“Sajangnim” is the romanized form of “사장님,” a respectful Korean term for a business owner, store owner, or boss. The name was inspired by the familiar Korean promotional phrase:
“사장님이 미쳤어요!”
It translates roughly to:
“The boss has gone crazy!”
Korean stores often use this playful expression when advertising discounts so large that the owner must be crazy to offer them. You might see it on a storefront sign or sale banner when prices have been dramatically reduced.
I wanted the name of my platform to capture that exact feeling: the excitement of discovering a designer item at a price that makes you stop and wonder whether the store owner has lost their mind.
Crazy Sajangnim helps shoppers discover discounted designer fashion from Korean and U.S. retailers without searching every store separately. Products are organized by market, brand, category, gender, price, and currency, making it easier to browse relevant deals and explore brands across both countries.
The platform is designed around four main ideas:
Discover designer products that are genuinely on sale.
Browse fashion from both Korean and American retailers.
Find established, emerging, and regionally popular brands.
Discuss purchases with a community instead of shopping alone.
The community is an essential part of the product—not an unrelated social feature added afterward. Members can share outfit photos, reviews, sizing information, styling ideas, sale discoveries, and honest opinions about whether an item is worth buying.
My goal is to create something that feels like co-shopping online.
If someone is considering a jacket, they should be able to ask how it fits. If another shopper owns it, they can share their experience. If someone finds the same item for less elsewhere, they can post the deal. Fashion discovery becomes a shared activity instead of a solitary product search.
Crazy Sajangnim also has a cross-border focus. Korean and American shoppers often encounter different selections, prices, currencies, and discounts. I wanted to make those markets easier to explore while also introducing international shoppers to Korean fashion culture and designers they might not otherwise discover.
I’m building this as a computer science student and software engineer who also happens to love fashion. Developing it has meant working across product search, data organization, authentication, database and storage systems, admin tools, community features, and deployment. AI-assisted development has helped me move faster, but the product direction comes from a problem I personally experienced and wanted to solve.
Crazy Sajangnim is still evolving. I’m working on improving the accuracy and speed of product discovery, adding more brands and retailers, and making the community experience genuinely useful. Future possibilities include saved products, personalized recommendations, price-drop notifications, retailer comparisons, and better ways for members to discover fashion through one another.
Ultimately, Crazy Sajangnim exists because finding great fashion should be easier—and online shopping should not have to feel lonely.
I would love feedback from other Indie Hackers:
Would you use a fashion platform that combines sale discovery with community advice?
Which would matter more to you: better deals, cross-market comparisons, or conversations with other shoppers?
What would make you return to a fashion community regularly?
If you have built a marketplace or community product, what helped you attract your first active members?

I’m working on Crazy Sajangnim because I love fashion, but I found the online shopping experience fragmented and isolating. Finding a genuinely discounted designer item often requires searching multiple Korean and U.S. r

The “co-shopping online” idea is the part I’d be most curious to see tested.
Right now, do you have any early users returning for the community itself, or is most of the observed behavior still around discovering products and deals?
I’m still in the early stages of development, so I don’t have enough user activity yet to identify a clear retention pattern. Most blog posts currently come from my friends and me, while the broader usage is still centered on discovering products and deals. Testing whether co-shopping and community interaction can become a reason for users to return is one of my main priorities.
That makes sense. It’ll be interesting to see whether the community layer becomes a reason people return, or whether discovery remains the main value people come for.
