Building Crazy Sajangnim: Making Online Fashion Shopping Feel More Like Shopping With Friends
Hi SaaS Hive! I’m Jinny, a Computer Science student at Boston University and a software engineer with a passion for fashion and community-driven products.
I created Crazy Sajangnim because online shopping is convenient—but making purchase decisions alone isn’t always fun. The platform brings designer-fashion sales and social interaction together, helping shoppers discover deals across Korean and U.S. retailers while sharing finds, shopping lists, styling ideas, and honest opinions through its integrated blog.
I’m building Crazy Sajangnim to make online shopping feel more like shopping with friends. I’d love to hear your feedback, feature ideas, and thoughts on how we can make the experience even better!

Welcome to SaaS Hive, Jinny! Love the idea. Anything that has to do with building a community and uniting people is much needed, in my opinion. I went looking for Crazy Sajangnim on SaaS Hive but couldn't find it yet. Are you launching soon?
Thank you so much for the warm welcome and thoughtful words! Crazy Sajangnim has now officially launched on SaaS Hive 🎉
The platform brings product discovery and fashion community together, allowing people to find designer deals while sharing styling ideas, reviews, and shopping advice. The community is still in its early stages—most blog posts currently come from my friends and me—but I’m excited to keep developing the co-shopping experience and learn how real users interact with it.
I’d really appreciate it if you could visit the page and share any feedback or suggestions you have:

Thank you again for encouraging the community side of the idea. That is one of the most important parts of what I hope Crazy Sajangnim can become!
Welcome, Jinny. Boston University to a live cross-border shopping community is a good combination, most people either know the code or know the fashion culture, rarely both. Curious what pulled you toward Korean and U.S. retailers specifically instead of starting with just one market, was that from your own shopping habits or a gap you noticed no other app was covering?
Thank you—that’s exactly what drew me to building Crazy Sajangnim. As a Korean American who has lived and shopped in both Korea and the U.S., I often noticed that the brands, discounts, and product availability could be very different between the two markets. Finding and comparing those options usually meant searching across multiple websites, currencies, and languages.
It began with my own shopping habits, but I also saw a broader gap: most platforms focus on a single market and separate product discovery from the conversations people naturally have while shopping. I wanted to connect both sides—helping people discover deals across Korean and U.S. retailers while creating a community where they can exchange styling ideas, reviews, and honest opinions. It’s still early, but that cross-border, co-shopping experience is what I’m most excited to keep developing.
Jinny, regarding your request for a feedback. Starting from today, there is a centralized place to request feedback on your product. It is called "Feedback Exchange" and you can learn more about it here: https://saashive.com/founder-community/request-feedback
Got it. Thanks!
Jinny, thank you for sharing the Korean American shopping story behind Crazy Sajangnim. That kind of personal reason behind a product is rare to hear directly from the founder. I want to ask you for something similar to what you gave me, an honest read from someone who thinks carefully about her own users. I am building FounderFlow, an AI Executive Chief of Staff that watches a founder's business, decides what matters, and tells them what to do next. Would you be open to taking a quick look and telling me honestly what stands out or what falls short?
Absolutely, I’d be happy to take a look! FounderFlow sounds really interesting, especially the idea of going beyond just giving founders more data and actually helping them decide what deserves attention and what to do next.
I’d be glad to give you an honest perspective on what stands out, what feels useful from a founder’s point of view, and anything that might feel unclear or could be improved. Feel free to send it over!
Here it is, Jinny: https://saashive.com/view-product/5e68abcc-d229-4748-aa7a-3a380346c1b7. Please do not hold back on the honest part, if anything feels unclear or unnecessary just say so, that is the read that actually helps.
FounderFlow addresses a real problem for founders managing multiple businesses: important emails, relationships, revenue signals, and follow-ups are often scattered across too many tools.
What stands out most is its focus on decisions rather than simply presenting more information. The Daily Briefing and Priority Inbox are designed to explain what needs attention, why it matters, and what action to take. I also like the confidence-grading concept because showing the evidence and certainty behind each recommendation could make the AI more trustworthy.
My main concern is that FounderFlow currently promises a lot. Features such as CRM, Company Memory, Executive Memory, Pipeline, and Pipeline Management seem to overlap, so clearer explanations or a realistic end-to-end example would make the differences easier to understand. I also noticed that the confidence system is described using four grades in some places but as High, Medium, and Low on the website. Using one consistent system would make the product clearer.
Because FounderFlow handles sensitive email, revenue, and relationship data, its long-term value will depend heavily on accuracy, privacy, and reliable integrations. Overall, though, the product has a strong premise and solves a meaningful problem. I would be interested in seeing how well it works once the integrations are fully available.
I’m also building Crazy Sajangnim, a platform that brings discounted designer fashion from Korean and U.S. retailers together with a community blog for an online co-shopping experience. If you have time, I would really appreciate an honest review or any feedback on my product as well: saashive.com/products/crazy-sajangnim
Jinny, this is exactly the kind of honest read I was hoping for. You are right that CRM, Company Memory, Executive Memory, and Pipeline sound like they overlap, that needs a clearer explanation or one real example walking through the difference, not just a feature list. Same with the confidence grading, four grades in one place and High/Medium/Low in another is a real inconsistency, not just wording. Passing both to the team. On Crazy Sajangnim, the shopping plus community idea is clear and the Korean/U.S. price comparison angle is a genuine gap in the market. The part I would push on is the community side itself, since you mentioned most posts are still you and your friends. What is your plan for getting real strangers posting, is it more founders like here, or something tied to the retailers themselves?
