ABOUT THE ROLE
Manifest is hiring a Account Manager to own a portfolio of corporate accounts - the company's top growth priority for 2026 and beyond. You'll serve as the primary point of contact for your clients and the internal owner of their outcomes. You'll convert pilots into long-term partnerships and work cross-functionally with Product, Operations, Sales, and Marketing to make every engagement deliver.
WHAT YOU’LL DO
- Own accounts end-to-end from signed contract through renewal and expansion
- Run client meetings, business reviews, and escalations with confidence
- Track account health, flag risks early, and ensure client KPIs are met
- Oversee onboarding, including data migration and technical implementation
- Bring structured client feedback to Product and Engineering to shape the roadmap
- Partner with Sales and Marketing on handoffs, case studies, and growth plays
- Build the playbooks and dashboards that make great account management repeatable
WHAT WE'RE LOOKING FOR
Must-haves:
- 6+ years in account management, client success, or a client-facing B2B SaaS role
- Proven track record growing accounts through renewals and expansion
- Ability to hold cross-functional teams accountable to client outcomes
- Strong judgment and bias toward action in ambiguous, fast-moving environments
- Analytical fluency and comfort using AI tools to increase output
Nice-to-haves:
- Experience building account management processes or playbooks from scratch
- Familiarity with legal tech, professional services, or regulated industries
THIS IS FOR YOU IF....
You want end-to-end ownership, not a narrowly scoped support role. You're energized by building structure where none yet exists. You want equity and real impact at a company reshaping access to justice.
THIS IS NOT FOR YOU IF....
You prefer a fully defined playbook over building one yourself. You're uncomfortable with full accountability for client outcomes. Five days a week in-office in New York City doesn't work for you.
