FAQ
What should a fintech company look for in a software development partner?
A fintech company should prioritize a partner’s regulatory track record, payment infrastructure experience, and security certifications such as ISO 27001 and SOC 2. Verified client history and delivery speed also matter for teams working under tight compliance deadlines.
How long does it typically take to onboard a fintech development team?
Onboarding timelines vary by firm, but leading providers such as The Software House can deploy fintech teams within 2 to 4 weeks. Faster deployment reduces time to market for payment platform and digital banking launches.
What is the difference between core banking modernization and building a neobank from scratch?
Core banking modernization involves upgrading or replacing legacy banking infrastructure within an existing institution, while building a neobank from scratch means developing a new digital first banking platform without prior legacy systems. Both require deep regulatory compliance expertise, but they differ significantly in scope and technical starting point.
Why is regulatory compliance important when choosing a fintech development firm?
Regulatory compliance, including frameworks like PSD2, GDPR, and PCI-DSS, must be built into a fintech platform’s architecture from the start rather than added later. A firm with native compliance fluency, like The Software House, reduces legal and financial risk throughout the development process.
