Inspiration

We started Homii from a simple but powerful question: “What if solo travelers could feel like they already have friends in every city they visit?”

After hosting over 100 travelers in Osaka and seeing how human connections made trips truly memorable, we wanted to create an app that makes these encounters natural and effortless.

What it does

Homii is a travel app that makes the real world feel magical by helping travelers connect with people, not just places.

Meet locals and other travelers — connect naturally during your trip
Chat instantly — break the ice with ease
Join or host activities — share experiences and explore cities together

AI Companion Lumi — Your AI guide knows your interests and every neighborhood, delivering intuitive recommendations for local connections and events—no chat needed, just natural discovery.

With Homii, travel isn’t just about sightseeing — it’s about people.

Challenges we ran into

Simplifying the core value: Avoiding feature overload and narrowing down to one promise — “meet people”
Onboarding design: Reducing stress from too many inputs, making the first experience fun and intuitive
Getting real reactions in Build in Public: Iterating until we reached genuine engagement and feedback
Map UI/UX: Preventing information overload while creating smooth, people-centered, animated interactions

Accomplishments that we’re proud of

Launched the mobile app (iOS & Android)
Successful pivot: From a “travel super-app” vision to focusing entirely on “meeting people while traveling”
Community co-creation: Users began posting profiles and spots themselves, sharing naturally on social media
Full-commitment team: An engineer left a large company, the designer dedicated full-time, and we spent 20 days co-living to build intensely

What we learned

Simplicity is the key to clarity: Focusing on “meet people while traveling” made the app instantly understandable
Travelers seek people, not information: Profiles and chats lit up users’ eyes far more than tourist spot details
Public sharing drives momentum: Daily/weekly updates in Build in Public created accountability and accelerated development speed
User involvement grows the product organically: Feedback and user-posted spots directly shaped improvements

What’s next

Vision

We aim to make the real world feel magical. In every city, travelers can naturally meet locals and friends, and travel as if they’re visiting people, not just places.

Short-term roadmap

Establish a U.S. legal entity
Expand activity creation/joining features so travelers can easily host and join meetups
Enhance profile + spot features to strengthen trust in “recommendations from people”
Optimize monetization (expanding RevenueCat-based subscription plans)
Experiment with our AI companion “Lumi” to lower the psychological barrier of starting conversations
