App Name - OppRadar( Opportunity Radar )
Category — Business
1. Concept
OppRadar is a personalized opportunity discovery platform designed to help users never miss life-changing opportunities.
Ironically, many people who would benefit most from opportunities like this Bubble x Contra challenge may never discover them simply because they didn’t know they existed, found out too late, or were overwhelmed by scattered information online. OppRadar exists to solve exactly that problem — making opportunities visible, personalized, and actionable before deadlines are missed.
The vision for OppRadar goes beyond a hackathon prototype. With the right support, it can become a trusted platform helping students, builders, creators, and professionals consistently discover opportunities that change careers and lives. Winning this challenge would help kickstart that vision — improving discovery systems, expanding opportunity coverage, and making personalized access to life-changing opportunities more accessible globally.
The app intelligently curates opportunities such as:
Hackathons
Scholarships
Remote jobs
Startup funding
Fellowships
Grants
Open-source programs
Users select their interests during onboarding, and OppRadar creates a personalized feed tailored to what matters most to them.
Unlike many prototype-only experiences, monetization in OppRadar is implemented with an actual fully working payment infrastructure(Stripe), making the business model immediately testable and scalable. This creates a believable path to revenue while keeping the free experience useful and accessible.

1. Personalized onboarding and interest-based recommendations
2. Fully functional Stripe-powered premium subscription flow(Video accompanied below)
3. Intelligent opportunity feed powered by selected interests

Built fully using Bubble’s Native Mobile Editor as a polished, mobile-first experience for the Bubble Spring Hackathon.

Awesome stuff!
LoopIn - My entry for the @Contra HQ x @Bubble challenge! 🌿
Category - Communication
Concept
LoopIn is a hyperlocal social network that connects neighbors inside the same apartment building through a private community feed, a neighbor directory, and a simple invite code system.
The app gives every building its own space where residents can share updates, ask for help, offer things, and stay informed about what's happening where they live — without the noise of generic social media or chaotic group chats.
Inspired by the energy of spring, connection, and new beginnings, LoopIn encourages neighbors to step out of anonymity, meet the people around them, and build a small but real community starting from their own front door.
Core Features:
- Private building feed with 4 post categories: Alert, Help, Offer, Question
- Neighbor directory with floor and apartment details
- Invite code onboarding — residents join only with a verified building code
- Image support on posts
- Like and comment on every post
- Admin dashboard with pinned announcements
- Automatic subscription tier based on number of apartments
Monetization Strategy - LoopIn uses a building-level subscription model paid by the administrator. The plan is calculated automatically based on apartment count.
Plans include:
Micro — 1 to 20 apartments — 29 RON/month
Standard — 21 to 60 apartments — 59 RON/month
Large — 61 to 150 apartments — 99 RON/month
Complex — 151+ apartments — 179 RON/month
30 days free trial, no credit card required. Residents always use the app for free.
Why It Matters - Most neighbors don't know each other's names. There is no local app in Romania that solves this. LoopIn is the first hyperlocal building community app in a market of 4.5 million urban apartments, with zero direct competitors.
Built With Bubble - Built fully using Bubble's native mobile editor as a polished mobile-first experience for the Bubble Spring Hackathon.
