Challenges

The problems we solve in fintech & financial services

  • Regulatory complexity

    SOC 2, PCI-DSS, KYC/AML, GDPR, CCPA, regional regulations. We architect for compliance from day one and support audits.

  • Security is non-negotiable

    Encryption, key management, threat modeling, OWASP Top 10, pen testing, secure SDLC. We treat security as a first-class engineering concern.

  • Trust signals matter

    Customers won't hand over money to a site that doesn't feel trustworthy. Design, copy, credentials, security badges and social proof all matter.

  • Real-time data complexity

    Market data, payment rails, account aggregation, transaction monitoring. We build the integration layers that make it work.

Frequently asked questions

01Do you build SOC 2 compliant applications?
Yes. We design and build with SOC 2 Type I and Type II in mind: access controls, audit logs, encryption at rest and in transit, vulnerability scanning, secure SDLC, incident response, business continuity, vendor management. We can partner with a vCISO and a compliance auditor (we work with Vanta, Drata, Secureframe) to accelerate your SOC 2 process.
02Can you integrate with Plaid, Stripe and other financial APIs?
Yes. We have deep experience with Plaid (account aggregation, identity, balance, transactions), Stripe (payments, Connect, Issuing), Adyen, Marqeta, Modern Treasury, and dozens of other financial APIs. We build the integration layers, handle the OAuth flows, and build the data normalization and reconciliation logic.
03How much does fintech development cost?
Marketing sites: $3,000–$15,000. Customer portals: $15,000–$60,000. Full lending/payment platforms: $50,000–$250,000+. We scope based on features, integrations and compliance requirements.
04Do you sign NDAs and BAAs?
Yes. We sign mutual NDAs before any confidential discussions. We can sign BAAs for healthcare and fintech engagements. We ensure all intellectual property transfers to you on final payment.
