The client aimed to scale their product offerings by empowering external businesses (in sectors like banking, education, healthcare, retail, professional services, nonprofit, etc.) with a plug-and-play solution for appointment booking, customer chat/call interactions, and email reminders—delivered via a unified, AI-powered interface.
Internally, the SUMO Scheduler team needed enhanced administrative tools—such as robust feedback modules and system notifications—to better support user retention, product improvement cycles, and seamless coordination with other development teams.
