FAQs
What is bespoke fintech software development?
Bespoke fintech software development is the process of designing, building, and maintaining custom digital solutions for financial services companies. Unlike off-the-shelf platforms, bespoke software is built around your specific business model, regulatory requirements, and user needs. This can include trading portals, KYC and onboarding systems, wealth management platforms, customer rewards programmes, market reporting tools, and payment processing solutions. At Buzz Interactive, we build fintech solutions on Microsoft .NET and Azure, with ISO 27001-certified security processes from day one, giving you a platform that's built to scale and built to comply.
How do you ensure the security of financial data?
Financial data security is non-negotiable. We've held ISO 27001 accreditation since 2017, the international standard for Information Security Management Systems (ISMS), with annual audits to verify our controls. In practice, this means encrypted data at rest and in transit, role-based access controls, multi-factor authentication, penetration testing, and infrastructure hosted on Microsoft Azure, which holds its own financial services compliance certifications.
What is the typical process for developing fintech software?
Our process follows an agile methodology adapted for the demands of financial services. It begins with a Discovery phase where we map out your business model, user journeys, regulatory requirements, and technical architecture. From there, we move into iterative development sprints, delivering working software regularly so you can test, gather feedback, and adjust priorities. Throughout development, we build in security reviews, compliance checks, and performance testing. We often recommend starting with a minimum viable product (MVP) to validate your concept with real users.
What technologies do you use to build fintech software?
Our core stack is built around Microsoft .NET and Azure, which provides the enterprise-grade performance, scalability, and security that financial services demand. For content-managed elements, we use Orchard Core CMS. We develop for both web and mobile, and can integrate with market data feeds, payment gateways, banking APIs, and third-party identity verification services as your product requires.
Do you offer ongoing support after launch?
Yes, and for fintech software, post-launch support is essential. Financial software requires continuous security monitoring, regulatory compliance updates, and performance optimisation to remain secure and compliant. Our after-launch support can be tailored to your needs, whether that's full system monitoring, security patching, infrastructure management, and compliance updates, or a lighter-touch arrangement where we're on hand when you need us. We also work with you to evolve the product as regulations change, markets shift, and your user base grows.
