Founding Customer Success Lead
South Park | Full-time | Onsite | Enterprise AI Sales
About the company:
An early-stage AI startup building a real-time AI sales coach for enterprise sales teams, helping companies improve sales performance through AI-powered insights and workflows.
About the role
We’re looking for our first Customer Success hire in the US to help build the Customer Success function from the ground up. This is a highly hands-on founding role for someone who thrives in fast-moving startup environments and wants real ownership from day one. You’ll work closely with founders, product, and early customers, helping shape onboarding, retention, expansion, and the overall customer experience as the company scales.
We’re specifically looking for someone who has seen strong startup CS teams operate up close and is excited by the opportunity to become the foundational Customer Success leader at a growing company.
What you'll do:
- Own customer relationships end-to-end, from onboarding through ongoing success and retention
- Partner closely with founders, product, and engineering teams
- Help build and improve CS processes, playbooks, and workflows from scratch
- Act as the voice of the customer internally
- Support expansion opportunities and help drive long-term customer value
- Operate in a highly dynamic, fast-paced startup environment with significant ownership and autonomy
What we are looking for:
- 3–5 years of Customer Success experience in B2B SaaS startups
- Experience working at high-growth early-stage startups
- Ideally one of the first Customer Success hires at a company
- Strong preference for candidates who have operated in lean, fast-moving startup teams rather than large enterprises
- Hands-on individual contributor mindset
- If you have management experience, it should be limited (up to ~2 years)
- Strong communication skills and customer-facing presence
- Highly motivated, ambitious, and excited to help build something from the ground up
- Comfortable with ambiguity and wearing multiple hats
Nice to have:
- Experience working with technical or AI-driven products
- Exposure to onboarding enterprise customers
- Experience helping scale CS operations or processes early on
Compensation:
- Competitive base salary
- Meaningful equity package
This is an opportunity to join at an early stage and play a foundational role in shaping the company, product, and customer experience from day one.
