Original: What Building a Fintech MVP Taught Me That SaaS Advice Never Mentions
Short summary
A founder building a fintech MVP solo learned that compliance architecture—KYC/AML, GDPR, PSD2—shapes design from day one, not licensing time. Prioritizing boring essentials (account creation, transfers) over exciting AI features, with immutable audit trails built in as a side effect of compliance-first thinking. The MVP proves product viability; real banking infrastructure and licensing come after proving the flows work.
- •Compliance considerations shape architecture early, not at licensing—KYC/AML, GDPR, and PSD2 constraints inform core design
- •MVP order matters: prove core banking flows before building AI features; boring correctness precedes innovation
- •Regulatory sandboxes like Bank of Lithuania's offer structured testing pathways; researching selection criteria early informs architectural decisions
Generated with AI, which can make mistakes.
Is this a good recommendation for you?
