PROJECTMinimal Chat Mobile App with Third-Party Integrations
RATIONALEFirebase Firestore gives you real-time message sync out of the box without building WebSocket infrastructure, which is critical for a seed-stage team moving fast. React Native with Expo lets your partial team ship to both iOS and Android without splitting effort. Using a managed chat SDK like Stream Chat reduces the most complex part of the build (message delivery, read receipts, media) to integration work rather than custom engineering.
TECH STACK
FrontendReact Native (Expo) for cross-platform iOS & Android

⚠ RISK FLAGS
!Vague integration scope: 'Integrations' is undefined — each third-party integration (e.g. Slack, WhatsApp Business API, payment gateways) can add 1-2 weeks and significant cost individually. Scope must be locked before dev starts.
!App Store approval delays: Apple App Store review for a new chat app can take 1-3 weeks, impacting your ASAP timeline. Plan for this buffer.
!Partial team risk: If your team is missing a mobile developer or backend engineer, hiring or contracting mid-project will cause delays and cost overruns.
!Seed budget pressure: At the lower end of seed funding, ongoing Firebase costs (Firestore reads/writes) or Stream Chat SDK fees may become a concern as user count grows — even at micro scale, monitor usage limits.
!Competing with established players: A generic chat app needs a clear differentiator or niche audience to gain traction. Lack of a defined use case is the #1 startup risk here.
