I am building a crowd-investing venture for the Swiss market and need a full digital solution—from intuitive mobile apps to a robust web portal. The core idea is simple: give investors a clear catalogue of projects, let them commit funds in a few taps, and then track performance in real time while staying compliant with Swiss regulations. Scope • Cross-platform build: iOS, Android, and a responsive web front end, all sharing a single codebase where practical (Flutter, React Native, or another modern framework—happy to hear your recommendations). • Secure Swiss-hosted backend with user authentication, KYC/AML checks, wallet or escrow integration, and a management console for project owners. • Investor dashboard showing committed capital, expected returns, payouts, and downloadable statements. • Messaging layer so investors and project sponsors can exchange updates within the app. • Multilingual interface (DE, FR, EN) with clean localisation support. If you have shipped finance or crowdfunding products before and can point to live examples, I would love to review them. Let’s discuss your proposed stack, timeline, and any questions you have to make sure we build this right the first time.
