FinTech Web & App Development

Secure, compliance-aware digital products for financial services and payment platforms.

Fremen Consulting builds websites and applications for FinTech companies — payment platforms, lending products, wealth tools, and financial SaaS that require security, compliance-aware design, and API-first architecture.

Common Challenges

Problems we solve for businesses like yours

Trust barriers block conversion

Financial products require immediate credibility. Generic design, missing security signals, and unclear regulatory compliance messaging cause prospects to abandon signup before completing KYC.

Compliance slows product velocity

Regulatory requirements for data handling, disclosures, and audit trails add complexity to every feature. Teams without compliance-aware development practices ship slowly or take unnecessary risk.

Legacy integrations block innovation

Connecting to banking APIs, payment rails, KYC providers, and core banking systems requires specialized integration expertise that generic web agencies lack.

Frequently Asked Questions

Clear answers to common questions in this industry

What should a FinTech website or app include?

A FinTech product should include clear value proposition, security and compliance messaging, transparent pricing and disclosures, streamlined onboarding with KYC, API documentation for B2B products, and trust signals such as regulatory registrations and security certifications.

Can you integrate Plaid and Stripe for financial products?

Yes. We integrate Plaid for account linking and financial data, Stripe for payments and Connect for marketplace payouts, and other banking APIs required for your product — with proper error handling, webhooks, and audit logging.

How do you handle compliance in FinTech development?

We build with compliance-aware practices including data encryption, access controls, audit trails, disclosure placement, and architecture aligned with SOC 2 and relevant financial regulations. Full compliance certification depends on your policies, legal review, and third-party audits.

Do you build both FinTech marketing sites and product applications?

Yes. We build marketing websites for trust and lead generation, and full product applications with authentication, dashboards, API integrations, and the secure infrastructure financial products require.

How long does a FinTech product development project take?

FinTech projects vary widely. Marketing sites take six to ten weeks. Product MVPs with payment integration and KYC typically take twelve to twenty weeks depending on regulatory scope, API complexity, and compliance requirements.
