Case Study: Monzo achieves shipping every two weeks through rapid prototyping and user testing with Marvel

How Marvel Keeps Monzo Shipping Every Two Weeks

Monzo, the fast-growing smartphone bank launched in 2015, needed design and development tools that could keep up with rapid scaling and an expectation of speed. The challenge was avoiding feedback bottlenecks and unreliable tooling while managing hundreds of concurrent projects and regularly validating ideas with stakeholders and customers.

Marvel provided a lightweight, scalable prototyping and user-testing platform that fits seamlessly into Monzo’s workflow, giving transparent, real-time visibility across teams. By replacing slow handoffs with interactive prototypes, enabling 30‑minute onboarding for new designers and supporting biweekly customer testing, Marvel removed bottlenecks, aligned teams and helped Monzo maintain a rapid two‑week shipping cadence.
