Siân Killingsworth

Creative Strategist and Senior Writer for Financial Services, Fintech, and Complex B2B Brands

I develop campaign concepts, messaging platforms, and multi-channel content that help complex businesses communicate with clarity, confidence, and distinction. My work spans financial services, institutional banking, retirement, investment management, technology, and other regulated or high-consideration industries.

I partner with marketing leaders, designers, subject-matter experts, product teams, and compliance stakeholders to turn business priorities and audience needs into clear, differentiated narratives. My work includes brand messaging, campaign development, thought leadership, website and digital experience content, sales enablement, lifecycle communications, and executive content.

I bring a strategic, audience-centered approach to every project, with particular strength in translating technical, regulated, or abstract subject matter into content that feels useful, credible, and human. I am equally comfortable shaping the idea at the beginning of a project, refining the message through stakeholder feedback, and carrying the work through execution across channels.
