The client is a European B2B service provider managing high-volume operations across multiple business departments. Their core product is a custom internal CRM ecosystem that handles complex deal pipelines, client communications and team workflows. The platform serves four roles (Sales, Operations, Managers and Admins) and processes thousands of active deals, tasks and client records every day. Our goal was to replace fragmented legacy tools with a unified, high-performance B2B SaaS web platform, covering product strategy, UX research, information architecture, UI design and a scalable design system.
