Built from inside the account.
Northline is a founder-led marketplace consultancy built around hands-on Amazon and eBay operation — commercial work, advertising, catalogue, reporting and account management.
No “passion for digital commerce” paragraph required.
Northline exists for a simpler reason: marketplaces need proper ownership.
Amazon and eBay sit at the intersection of advertising, content, catalogue management, operations, pricing, fulfilment and commercial decision-making.
Northline brings those disciplines together and works directly inside the marketplace — diagnosing problems, executing priorities and reporting on what changed.
Close to the work by design.
Founder-led isn’t something Northline needs to disguise. It’s part of the proposition.
Clients are not passed from salesperson to account manager to junior executive. The person discussing the commercial problem stays close to the account, decisions and execution.
The experience behind Northline is practical marketplace work: launching and managing channels, building listings and catalogues, running advertising, monitoring account health, structuring reporting, solving operational issues and deciding where effort should go next.
What the business is being built around.
Commercial before cosmetic.
Creative and dashboards matter, but not more than understanding what makes or loses the business money.
Execution earns the strategy.
Recommendations carry more weight when they come from proximity to implementation.
Report decisions, not noise.
Data should explain what happened, why it matters and what happens next.
