B2B Growth Marketing Manager

About the Role

We are seeking a B2B Growth Marketing Manager to help execute and scale Sonder Mind’s B2B growth engine across health systems, payors, Veterans Affairs (VA), and enterprise referral partners. This role plays a critical part in how Sonder Mind shows up to partners through clear messaging, thoughtful campaigns, and consistent execution that supports both pipeline growth and referral activation.

Reporting to the B2B Growth Marketing Lead, you’ll own the execution and optimization of full-funnel B2B marketing programs, working closely with cross-functional partners across Sales, Partnerships, Lifecycle Marketing, and Product Marketing.

This is a hands-on, execution-focused role for a strong B2B marketer who values ownership, precision, and measurable impact. The ideal candidate brings a growth mindset, attention to detail, and a bias for action—building repeatable processes, learning from data, and collaborating closely with stakeholders to help scale Sonder Mind’s B2B business and expand access to mental health care.

• Partner with Lifecycle Marketing and enterprise teams to support referral-to-care conversion.
• Monitor the referral journey, identify friction points, and help implement data-informed improvements that increase activation and yield.
• Support testing and iteration across referral touchpoints to reduce drop-off and improve outcomes.
• Develop and maintain sales enablement and partner-facing materials including pitch decks, one-pagers, case studies, nurture templates, and thought leadership.
• Adapt content to support different partner audiences and moments in the funnel.
• Ensure materials are easy to use, up to date, and aligned with Sonder Mind’s positioning and value proposition.

• Manage calendar and execution of industry conferences, webinars, round tables, and co-marketing initiatives.
• Coordinate lead capture, post-event follow-up, and performance reporting to ensure events contribute to pipeline and partner engagement.

Success in this role is measured by consistent, high-quality execution that translates into meaningful business impact and strong cross-functional partnership.
