truloop - AI Native Social App

Inspiration

After building NAVER BAND to 20M users within less than 2 years, founder Suman Park noticed a global shift away from public posting toward private sharing. He envisioned that the everyday act of four friends meeting for a meal and conversation could be transformed if AI helped from scheduling the gathering to creating a recap afterward — making it possible to popularize an AI-powered social app specialized for small-group meetups.

The goal was to create a safe, private, yet personal space where small groups can gather, share, and design memories together.

What it does

Problem
People juggle hundreds of group chats but only meet a few groups regularly. According to surveys, 79% use collaboration tools, yet 41% still struggle with coordination.

Solution – truloop solves this with:

Scheduling → Loops: AI assistant organizes group plans, collects availability, and generates a D-day card with calendar integration.
Private photo space: Each member can contribute and also remove photos that include their own face for safety.
AI-powered creativity: One-tap poster templates and auto-generated Loop Stories.
Personalized memory design: Each member sets their own Loop cover, reflecting their perspective.
Cross-market support: Localized in Korean, English, and Japanese; available in KR/US/JP stores.

How we built it

Tech stack:

Swift (iOS), Kotlin (Android), React Native (shared UI)
Firebase (auth, storage), AWS (media + AI services)
Firestore (real-time sync), PostgreSQL (wallet & entitlements)
RevenueCat (subscriptions & consumables), OpenAI + custom ML (AI posters/stories), Kakao API (invites), Google Calendar/iCal integration

Monetization model:

LPY coins (consumables): pay-as-you-go for AI services.
Premium subscription: unlimited loops/scheduling, original uploads/downloads, subscriber-only templates, + 1,000 LPY monthly stipend.
RevenueCat is used as the backbone for subscription + consumable management across iOS and Android.

Challenges we ran into

Synchronizing entitlement logic across iOS and Android while keeping UX consistent.
Designing adaptive paywalls for different markets (KR/US/JP).
Creating and syncing LPY (internal currency) was difficult due to lack of prior experience in virtual economy design.
Managing automated monthly LPY grants and wallet balance logic.

Accomplishments that we're proud of

Successfully synchronized entitlement logic across iOS and Android.
Automated monthly LPY grants and wallet balance management.
Integrated adaptive paywalls across different markets (KR/US/JP).
Learned about RevenueCat’s Virtual Currency feature, which was a perfect fit for us. By adopting it, we dramatically reduced development time.
Validated that leveraging well-provided SaaS is advantageous for early-stage products, saving both time and complexity.

What we learned

Cross-platform monetization is possible with careful entitlement + consumable design.
AI-native social apps thrive when safety and personalization are prioritized.
RevenueCat’s centralized setup allowed testing offers and prices across markets efficiently.
Trust features (like face-based photo removal) are crucial in private sharing contexts.
Well-designed SaaS solutions (e.g., RevenueCat Virtual Currency) can accelerate early-stage product development.
