Senior Customer Success Manager
Thrive is a leading behavior change technology company founded by Arianna Huffington in 2016 with the mission to end the stress and burnout epidemic. Thrive helps individuals and organizations improve well-being, performance and mental resilience with its AI-powered behavior change technology platform. Thrive’s Microsteps – small, science-backed steps to improve health and productivity – have been adopted by employees at more than 125 organizations in over 140 countries, from frontline and call center workers to executives at multinational companies.
If you’re not sure that you’re 100% qualified, but this sounds like a role you would Thrive in – we want you to apply! We believe skills are transferable and passion for our mission goes a long way.
The Senior CSM owns the customer relationship after the sale: delivery, adoption, ongoing engagement, renewals, and growth. This is a high-touch model. You will own a portfolio of roughly five to seven enterprise accounts so you can get deeply ingrained in each one, manage executive-level relationships, and act as a genuine strategic partner. AI is central to where we are taking this team. We are reengineering how Customer Success works so AI raises the quality of every touchpoint, from executive prep to renewal strategy, and this role helps lead that. We are looking for someone who wants to help build that way of working, not inherit a finished one!
How You'll Contribute
- A defined portfolio of enterprise customers across the lifecycle, including the renewal and expansion number.
- Executive relationships, using AI to prepare: synthesizing stakeholder context, priorities, the recommended narrative, and likely questions so you walk into every high-stakes meeting calibrated.
- Client-ready storytelling: translating Thrive research, product updates, and data into industry-specific narratives, with AI sharpening the translation.
- Executive-ready QBRs, renewal decks, and expansion proposals grounded in usage data and business impact, not just activity reporting.
- Early detection of churn risk and expansion opportunity, bringing recommended actions rather than flags.
- Renewal and expansion forecasting with Sales, and cross-functional delivery with Product, Marketing, and Leadership.
Qualifications & Skills
- BA/BS degree or relevant work experience
- 7 - 10+ years in customer success, ideally with two or more at a SaaS technology company.
- A track record of owning renewals, retention, or expansion on a small book of enterprise accounts, with deal sizes in the $100K to $5M range. We want a number you owned, not relationship management alone.
- Hands-on use of AI in your actual workflow (meeting prep, communications, decks, data synthesis) and the judgment to evaluate and refine what it produces rather than shipping raw output. You will help set the bar for how our CS team uses AI.
- Strong executive communication: you make the complex clear and you can hold your own in the room with senior stakeholders.
- US-based and eligible to work in the US, comfortable working Eastern hours.
Who You Are
- Proactive and self-directed. You see what needs to happen and move, and you own work end to end.
- Adaptable in a fast-paced environment. You stay steady when priorities shift and there is no playbook.
- Naturally curious and always learning. You go looking for context, and you fold what you learn back into the work.
- Clear and compassionately direct. You simplify the complex and deliver hard messages with care.
- Gritty and entrepreneurial. You treat constraints as facts, not excuses, and you have a healthy relationship with setback.
- Mission-aligned. You have thought about wellbeing and human performance beyond the surface.
