Case Study: Radius Bank achieves 20% NPS increase, 50% lower support volume and 137% app rating boost with Narmi

Narmi Delivers State of The Art Mobile & Online Banking Platform to Radius Bank

Radius Bank, a $1.4bn digital‑only bank based in Boston, wanted to streamline its customers’ digital experience and rapidly modernize platform capabilities. To meet that aggressive timeline it selected Narmi to deliver an omni‑channel, mobile‑first online and mobile banking platform that integrates external FinTechs and supports long‑term growth.

Narmi implemented a feature‑rich solution that centralized support via its API into Radius’s Oracle CRM, improved fraud prevention by risk‑scoring transactions, and added FinTech integrations and modular components like Cards, Billshark and Lemonade. The deployment drove measurable gains: 20% higher NPS, 50% lower support volume, 63% faster support response time, a 137% jump in app store rating, and contributed to Radius being named Bankrate’s #1 Online Bank in 2020.
