Banking & neobanks
Account management, card issuance, transaction feeds, and multi-currency support. Built on Stripe Treasury or similar BaaS providers.
Trading & portfolio tools
Trading dashboards, portfolio trackers, crypto wallets, and market data visualization. Real-time pricing and historical charting.
Personal finance apps
Budgeting apps, expense trackers, savings goals, and spending insights. Plaid integration for account aggregation.
B2B financial tools
Accounting integrations, invoice management, expense reporting, and treasury dashboards for growing businesses.
How much does it cost to build a FinTech app?
FinTech app development typically starts at $2,500 for a simple MVP and can reach $100,000+ for a fully featured platform with compliance workflows, multi-currency support, and third-party integrations. LSD Dev Studio publishes transparent pricing tiers — most FinTech MVPs fall between $8,000 and $25,000.
How do you handle PCI-DSS and financial compliance?
We build on compliant infrastructure (Stripe, Plaid, AWS) and follow PCI-DSS best practices — tokenization, encryption at rest and in transit, secure key management, and minimal card data storage. We don't claim to be lawyers or compliance officers, so for regulated use cases we work alongside your compliance team.
Can you integrate with banking APIs like Plaid or Yodlee?
Yes. We regularly integrate Plaid for account connection, balance checks, and transaction history. We also work with Stripe, Stripe Treasury, Square, Adyen, and other payment processors. For international banking, we use providers like Wise and Currencycloud.
How long does it take to build a FinTech MVP?
A simple FinTech MVP (user accounts, payment integration, basic dashboard) takes 6-10 weeks. A more complex product (KYC, multi-user roles, transaction workflows, admin panel) takes 12-20 weeks. Timeline depends on compliance complexity and integration count.
What tech stack do you use for FinTech apps?
Next.js and React for web, React Native for mobile, TypeScript across the stack, PostgreSQL for relational data, and Node.js for backend services. For payment and banking integrations, we use Stripe, Plaid, and Stripe Treasury. Infrastructure runs on AWS or Vercel.
Do you build trading or crypto platforms?
We build trading dashboards, portfolio trackers, and crypto wallets. For exchange-level infrastructure (order matching engines, custody solutions), we typically partner with specialized providers and build the user-facing layer. We avoid regulated custody and lending without a licensed partner.
How do you ensure FinTech app security?
Security is baked in from the start — encrypted data at rest and in transit, secure authentication (MFA, biometrics, OAuth), input validation, rate limiting, audit logging, and regular dependency updates. We follow OWASP Top 10 practices and use security headers, CSRF tokens, and proper session management.
Can you build a FinTech mobile app for both iOS and Android?
Yes. We typically use React Native to build one codebase that deploys to both platforms, with native feel and biometric authentication. For apps requiring deeper platform integration, we can build native iOS (Swift) and Android (Kotlin) separately.
