Common Challenges
Problems We Solve for Financial Services
We understand the unique challenges fintech companies face. Here's how we help.
Compliance Slowing Down Development
Regulatory requirements (PCI-DSS, SOC2, GDPR) adding friction to every release. We build compliance into the development process so it doesn't slow you down.
Legacy Systems Limiting Innovation
Old core systems that are hard to change and integrate with. We help modernize incrementally while maintaining stability and compliance.
Security Concerns with Third-Party Teams
Worried about giving external teams access to sensitive systems. We follow strict security protocols and can work within your security frameworks.
Finding Engineers Who Understand Finance
Generic developers who don't understand financial concepts or compliance. Our teams include engineers with direct fintech experience.

FAQs
Common Questions from Financial Services
Answers to questions we frequently hear from fintech companies and financial institutions.
Do you have experience with PCI-DSS compliance?
Yes, we've built PCI-DSS compliant payment systems and understand the requirements for handling cardholder data. We implement proper encryption, tokenization, access controls, logging, and security practices required for PCI compliance. We can also help you prepare for PCI audits.
Can you help us build a trading or investment platform?
Yes, we've built trading platforms handling real-time market data, order management, portfolio tracking, and regulatory reporting. We understand the performance requirements (low latency, high throughput) and data accuracy needed for financial applications. We've worked with market data feeds, order routing, and settlement systems.
How do you handle sensitive financial data?
We follow strict security practices: encryption at rest and in transit (TLS 1.3, AES-256), proper access controls (RBAC, least privilege), comprehensive audit logging, secure development practices (code reviews, SAST/DAST), and regular security assessments. We can work within your existing security frameworks and compliance requirements.
Do you work with startups or only established financial institutions?
We work with both. For fintech startups, we help build MVPs with proper security foundations that won't need rewrites when you scale or face audits. For established institutions, we help modernize legacy systems, build new products, or scale engineering capacity while maintaining compliance.
Can you integrate with banking APIs and payment processors?
Yes, we have experience integrating with Plaid, Stripe, Marqeta, Galileo, banking core systems, ACH networks, card networks, and various payment processors. We understand the nuances of financial integrations including idempotency, reconciliation, and error handling.
How do you handle regulatory requirements across different jurisdictions?
We build systems with regulatory flexibility in mind—configurable compliance rules, proper data residency handling, and audit trails that satisfy multiple regulators. We've worked with US, EU, and other regulatory frameworks and understand the differences in requirements.
What security certifications or practices do you follow?
We follow OWASP Top 10, implement secure SDLC practices, conduct regular code reviews for security issues, use static and dynamic analysis tools, and can work within SOC2 Type II certified processes. Our developers are trained on secure coding practices specific to financial applications.
Can you sign NDAs and work under strict confidentiality?
Absolutely. We routinely sign NDAs and work under strict confidentiality agreements. We understand the sensitivity of financial systems and can accommodate your security requirements including background checks, restricted access, and audit requirements.
