At HubSpot, we’re on a mission to help millions of organizations grow better. Our platform is used by businesses worldwide to manage their marketing, sales, service, and operations — and under the hood, our product is built to be flexible, secure, and empowering for both our customers and our own engineering teams. We believe in autonomy, curiosity, and building a workplace where everyone can thrive.

Flywheel: Help HubSpot’s internal sales teams become the most efficient and effective in the industry by creating AI-powered tools to eliminate repetitive tasks, enhance collaboration, and drive consistent deal progression.

Our goal is to enable each sales rep to improve deal velocity, adopt best practices seamlessly, and spend more time engaging with prospects/customers, providing an excellent buying experience.

The AI Tools & Context team is building internal tools that power smarter and more efficient AI agents. There are multiple agents used across the Flywheel Group, and our mission is to build a reusable set of tools that allows us to rapidly extract, reuse, and act on contextual insights. We also aim to create a more unified user experience by allowing multiple agents to seamlessly share context when a user is transferred between them.
