Account Manager / Founding Customer Success Manager
Location: New York, NY
Work Model: Onsite, 5 days/week
Industry: AI / Vertical SaaS / Voice AI

About the Company

Our partner is an early-stage AI company building voice, SMS, and text agents that automate sales for businesses serving families. The company has grown to roughly $1M in revenue in about four months, is working with customers like Nike, Disney, and IMG, and is backed by notable operators and investors. The team is still very small and in true build mode.

About the Role

Our partner is hiring a Founding Account Manager / Founding CSM to build the post-sales function from scratch. This person will own the customer experience after a deal closes, including onboarding, implementation, integrations, go-live, and ongoing account management. The role is highly cross-functional and best suited for someone who wants real ownership in an early-stage environment.

What You’ll Do

• Own customer relationships end-to-end after contract signature
• Lead onboarding and implementation for new accounts
• Coordinate integrations across CRM, scheduling, Twilio, email, and related systems
• Help customers get live and ensure strong early adoption
• Run check-ins, manage campaigns, and deliver a high-touch customer experience
• Build the post-sales playbook and define processes from 0→1
• Partner closely with founders to improve deployment and customer outcomes

What They’re Looking For

• 3–4+ years of startup experience minimum
• Strong preference for someone who has worked as a founding employee or in a very early-stage startup environment
• Experience in Customer Success, Account Management, Implementation, or a similar post-sales function
• Comfortable building processes from scratch rather than inheriting a mature function
• Strong communication skills and ability to manage premium, white-glove customer relationships
• Bonus if they’ve worked at a vertical AI, voice AI, or GTM-oriented company and understand tools like CRM, lead scoring, and messaging systems
• Willing to relocate ASAP is a plus
