Sometimes you’re stuck in a customer success role where you’re focused on solving tickets instead of building relationships and driving customer outcomes. If you enjoy understanding customers, solving business problems, and turning relationships into long-term value — then Arena is the company you’re looking for.
About the Role:
We’re looking for a Customer Success Manager to help our customers maximize the value they get from Arena.
You’ll work across the full customer lifecycle — from onboarding and adoption to retention, renewals, and expansion — while partnering closely with Sales, Product, Engineering, and Support. This is a highly collaborative and hands-on role. As part of a growing Customer Success organization, you’ll also have the opportunity to help build and improve our CS processes, playbooks, and success metrics.
What you will be doing:
•
Own a portfolio of customers and build strong, long-term relationships with key stakeholders.
•
Lead onboarding, adoption, and customer success initiatives throughout the customer lifecycle.
•
Understand customer goals and translate them into clear success plans and actionable next steps.
•
Monitor customer health, adoption, and engagement to proactively identify risks and opportunities.
•
Drive retention, renewals, and expansion opportunities in partnership with Sales.
•
Work closely with Product, Engineering, and Support to solve customer problems and communicate product feedback.
•
Conduct regular customer meetings, business reviews, and QBRs with key stakeholders.
•
Help build and improve Customer Success processes, playbooks, and success metrics.
Must-Have Experience:
•
3+ years of experience in Customer Success, Account Management, or a similar customer-facing role, preferably in B2B SaaS.
•
Experience managing the customer lifecycle, including onboarding, adoption, retention, and renewals.
•

•
Excellent communication and stakeholder management skills across both technical and business audiences.
•
Strong organizational skills and ability to manage multiple customers and priorities simultaneously.
•
Experience working cross-functionally with Sales, Product, Engineering, and Support teams.
•

Nice-to-Have Experience:
•
Experience with enterprise customers, global brands, publishers, media, sports, or creator-focused businesses.
•
Experience with SaaS, MarTech, AdTech, Creator Economy, or AI products.
•
Experience with Salesforce or other CRM platforms.
•
Technical curiosity and familiarity with APIs, integrations, and web technologies.

Experience building Customer Success processes or playbooks in a startup environment.
