SeatOS is on a mission to transform and digitize the land & sea travel industry, making all routes instantly bookable by anyone. Part of the leading land & sea transportation group, Travelier, SeatOS is building the dominant Transport Management System (TMS) in APAC. 

We are hiring for an Account Growth Manager to join us on this mission. This role is ideal for someone who thrives at the intersection of customer success and commercial growth, and is excited to help define what great looks like as we scale. You'll work closely with customers to ensure they're getting the most value from SeatOS, while also identifying opportunities to deepen and grow the relationship.

This is a hybrid role—leaning towards Customer Success (70%) with a light commercial focus (30%)—and will report into our Head of Sales & Accounts. This role will be based out of Bangkok and cover accounts across Southeast Asia.

Responsibilities will include:

Success & Adoption (70%)

• Lead onboarding for new accounts and ensure smooth handover from implementation to active usage.
• Drive ongoing product adoption through training, relationship-building, and proactive check-ins.
• Monitor customer health using data and define interventions before problems arise.
• Run regular business reviews with clients to surface wins, gather feedback, and reinforce ROI.
• Act as the customer’s internal advocate—helping us shape roadmap priorities and fix pain points.
• Collaborate with support and product teams to resolve issues quickly and improve CX.

Commercial & Expansion (30%)

• Spot upsell opportunities (e.g. adding POS, white-label, additional locations) and qualify for AE/founder handoff.
• Own smaller upsell motions end-to-end where commercial complexity is low.
• Support renewal planning by ensuring high usage and stakeholder alignment ahead of term.
• Help maintain account documentation (contract terms, usage metrics, relationship maps).
