Questions We Hear Every Week

FinTech app development typically ranges from $40,000 for a focused MVP to $250,000+ for a full-scale, multi-product platform. The cost depends on the app type (wallet, neobank, lending, wealthtech), compliance scope (PCI-DSS, PSD2, KYC/AML), number of integrations, and platforms. After a free scoping session we provide a detailed, fixed-price proposal. No hourly billing surprises.
A compliance-ready fintech MVP usually launches in 12–16 weeks. A full-scale platform with multiple products, admin panels, and deep banking integrations takes 5–9 months. We work in two-week agile sprints and deliver a working prototype by week 3 so you can validate early.
Yes. We build compliance in from day one: PCI-DSS for card data, PSD2 and Open Banking for the EU/UK, GDPR and CCPA for data privacy, KYC/AML with automated identity verification, and SOC 2 / ISO 27001 aligned security controls. We also support region-specific frameworks such as RBI guidelines (India), FCA (UK), and FinCEN (US).
Every app ships with a zero-trust architecture: AES-256 encryption at rest, TLS 1.3 in transit, biometric and multi-factor authentication, tokenization of sensitive data, device binding, real-time AI fraud detection, and mandatory penetration testing (VAPT) before launch. We never store raw card or credential data and follow OWASP MASVS mobile security standards.
We integrate 30+ payment and banking providers including Stripe, Adyen, Plaid, Razorpay, UPI, PayPal, Braintree, Marqeta (card issuing), Dwolla (ACH), and Wise (cross-border), plus Open Banking / account aggregation APIs. We also build direct core-banking, ledger, and card-network integrations for enterprise clients.
Yes. We build AI-powered fraud and anomaly detection, credit-scoring and risk models, robo-advisory and portfolio automation, conversational banking assistants, and document/KYC intelligence. Our AI team designs models that are explainable and audit-ready, essential for regulated financial products.
We deliver the full stack: native iOS and Android (or Flutter/React Native) apps, web dashboards, admin and compliance back-office, secure APIs, and cloud infrastructure. You get one accountable team from architecture and design through to launch, monitoring, and scaling.
Appther has shipped 200+ products across 15+ countries, including AI-driven and regulated financial platforms. We combine bank-grade security, compliance-first architecture, and modern UX with fixed-price delivery, a prototype in week 3, and 90 days of free post-launch support, so you launch fast without cutting corners on trust.
