Case Study: Monzo Bank achieves higher performance review completion and better calibration with Lattice

Simplifying Performance Reviews to Drive Participation with Monzo Bank

Monzo Bank, a fast‑growing UK challenger bank, faced a costly, opaque performance-review process run on Google Forms and Sheets that was time-consuming, hard to track when people moved teams, and a poor experience for managers and employees. To scale its people processes without losing its culture, Monzo selected Lattice (Platform w/ Premium Support) to modernize performance management.

Lattice implemented a centralized performance platform integrated with Monzo’s HRIS, giving managers a bird’s‑eye view, automated reminders, peer‑review and self‑review workflows, and a calibration feature. As a result, Lattice drove higher completion rates cycle‑upon‑cycle, improved the quality and usefulness of reviews, reduced people‑operations queries and admin time, and produced rating‑change data used to inform Monzo Bank’s diversity and inclusion efforts.
