The Flywheel Group supports HubSpot's vision to build a product that powers its own teams - "HubSpot runs on HubSpot." This team builds the core experience that enables Customer Success and Customer Service reps to operate efficiently within the HubSpot platform.

Our work focuses on creating the next generation of rep experiences: a central, intelligent interface that supports reps with contextual data and actionable alerts, tools that help identify high impact opportunities and drive consistent execution, and AI powered experiences to eliminate repetitive tasks and enhance workflows.
