Who our FinTech Software Development service is for

Our fintech work combines engineering with our in-house security practice: VAPT before launch, secure coding, encryption and least-privilege access. We integrate with regulated partners for KYC, payments and credit data rather than cutting compliance corners.

FAQs

FinTech Software Development: frequently asked questions

Do you help with RBI licences?

We are a technology partner, not a legal or licensing adviser. We build products that work with licensed partners such as banks, NBFCs and payment aggregators, and support the technical documentation your compliance advisers need.

How do you handle KYC?

Through licensed KYC and verification providers: PAN checks, Aadhaar-based and video KYC, DigiLocker document fetch and bank account verification, with consent capture and secure storage.

How is financial data secured?

Encryption in transit and at rest, strict access control, audit logs, secure key management and VAPT before every major release, with data kept in India where required.

Can you integrate with Account Aggregators?

Yes. We integrate with Account Aggregator ecosystem providers to fetch consented financial data for lending and advisory use cases.
