Marketbridge Promotes Katie Jeffries to Client Partner, Growth

Marketbridge has promoted Katie Jeffries to Client Partner, Growth, expanding her responsibilities as the agency continues to develop its presence across Europe.

Jeffries is returning to Marketbridge after taking a summer break with her family. In her new role, she will work with Sian Church, Fiona McKenzie, and the wider team on growth initiatives and client relationships across the region.

The promotion comes as B2B marketing agencies face increasing pressure to connect strategic planning with measurable commercial outcomes. Clients are looking for partners that can bring together marketing, sales, data, technology, and customer insights while maintaining a clear focus on business priorities.

For client leadership teams, this means managing more than campaign delivery. Growth-focused roles increasingly involve understanding client objectives, coordinating specialist capabilities, identifying new opportunities, and helping organizations respond to changes in buyer behavior and market conditions.

Jeffries’ expanded remit also comes at a time when B2B marketing is becoming more complex. Longer buying cycles, multiple stakeholders, changing digital channels, and the growing use of AI are influencing how businesses approach demand generation and customer engagement.

Marketbridge has been shortlisted eight times at the 2026 B2B Marketing Awards, including in the Global B2B Marketing Agency of the Year category. While awards recognition does not determine business performance, it provides context for the agency’s current focus on growth and client work.

The appointment highlights the changing role of client leadership within B2B agencies. As marketing programs become more integrated, client partners are increasingly expected to connect commercial objectives with strategy, execution, and long-term relationships.

For MarTech and B2B marketing professionals, Jeffries’ promotion reflects the continued importance of growth leadership in helping agencies and clients navigate a market shaped by data, technology, and evolving customer expectations.
