Growth Associate | Fast-Growth Ecommerce Brand | London in England

The Client

Our client is a Fast-Growth Ecommerce Brand that has scaled at exceptional speed by building products people genuinely love to share. Operating in a highly social, content-driven category, the business has achieved massive organic reach and has become one of the standout founder-led success stories in the UK.

What sets this company apart is how it blends creativity with commercial discipline. Growth decisions are driven by experimentation, data, and a willingness to move before the market catches up. The team is small, ambitious, and hands-on, with senior leaders deeply involved in strategy and execution. This is an environment where good ideas are acted on quickly and ownership is encouraged from day one.

With strong foundations already in place, the business is now focused on unlocking its next wave of growth through new platforms, new regions, and smarter use of emerging technology.

The Role

This Growth Associate position is designed for someone who wants to sit close to the engine room of a scaling ecommerce business. You’ll play a key role in identifying, testing, and scaling new revenue opportunities, particularly across marketplaces and alternative sales channels.

Working directly with a senior growth leader, you’ll take responsibility for long-term initiatives that have the potential to materially shift revenue performance. Rather than maintaining existing channels, your focus will be on what’s next — whether that’s entering untapped markets, trialing new platforms, or building internal capabilities that give the business an edge.

The role suits someone who enjoys autonomy, thrives in fast-paced environments, and is excited by the challenge of turning loose ideas into measurable commercial outcomes. This is an office-based role (4 days per week) in central London.

Key Responsibilities

• Identify and launch new marketplace and platform opportunities
• Take ownership of high-potential growth initiatives from research through to execution
• Investigate emerging tools, technologies, and services that can unlock incremental revenue
• Lead exploratory projects that could create long-term strategic advantage
• Test, iterate, and scale ideas quickly using a data-led approach
• Contribute directly to revenue growth across international markets

What the Client Would Like to See

• A strong commercial instinct and comfort working towards clear growth targets
• Someone who naturally looks ahead and anticipates future opportunities
• Evidence of proactive idea generation and rapid experimentation
• A genuine interest in how ecommerce, marketplaces, and consumer behaviour are evolving
• Practical experience applying AI or automation to solve problems or drive results

What We Would Like to See

• Experience launching or scaling a channel, product, or marketplace from scratch
• Exposure to ecommerce or digital-first consumer brands
• Examples of projects where you’ve driven tangible revenue impact
• Confidence operating in fast-moving, low-structure environments
• A bias toward action, ownership, and continuous learning
