Be Part of the Story
OnCommerce is constantly evolving. Everyone here plays a hands-on role in shaping what comes next, building brands that make an impact across global markets. There’s no red tape or rigid corporate structure; just smart people taking ownership and figuring things out as we build something big together. The pace is fast, priorities shift, things aren’t always perfectly set up, and you’ll often need to get stuck in and solve problems. But if you thrive in that kind of environment, you’ll have real influence, real ownership, and the chance to grow with a rapidly scaling business.
About the Role
The Head of Seller Demand- B2B Marketing is accountable for building and scaling a global seller acquisition engine, covering the full journey from awareness lead sign-up across 21 international markets. You are accountable for how sellers discover, evaluate, and choose to sign up across OnBuy, EasyShop, and Comet - driving consistent, high-quality inbound demand at scale.
You will own both B2B demand generation and seller sign-up, ensuring we attract the right sellers through localised, high-converting experiences, while accelerating speed to first sale. You will build and operate a multi-market, AI-powered acquisition system across:
-
PR
-
Social (LinkedIn-first)
-
CRM & lifecycle
-
Content & messaging
-
Partnerships (via direct report)
This is a tech-savvy, data-driven role, operating across 19+ languages and leveraging AI-powered automation across LinkedIn, email, social, and PR to scale seller acquisition. You will design and run a repeatable system that delivers predictable lead and sign-up growth, balancing Cost per Lead (CPL) and Cost per Acquisition (CPA) while driving seller quality (lead scoring).
This includes leveraging both organic and data-driven acquisition strategies, including the use of external lead data and CRM activation to scale seller demand efficiently. This role is about driving interest and intent - not managing sellers post sign-up. You do not own onboarding, activation, or seller performance.
In short: Drive high-quality seller demand at scale - turning attention into sign-ups across all markets.
This role is responsible for filling the pipeline with high-quality sellers. Seller, Sales and Onboarding teams are responsible for what happens next.
