Stewart-Walvin

Tom Stewart-Walvin is an Associate Director at Rostrum, where he leads communications programmes for clients across professional and financial services. His remit spans media relations, content strategy, thought leadership and integrated campaigns, with a focus on translating complex subject matter into commercial narratives that move the needle for B2B brands.

Tom has spent his career advising organisations operating in technical and highly regulated markets, from law firms and accountancy practices to asset managers and fintech businesses. He works closely with senior leaders to sharpen positioning, build profile in target sectors and turn internal expertise into external authority. Clients value his ability to interrogate a brief, find the angle that journalists and buyers actually care about, and hold a campaign to a clear set of commercial outcomes.

Day to day he splits his time between counsel and craft. He chairs client strategy sessions, edits long-form thought leadership, briefs national and trade press, and coaches teams on how to land sharper stories in a crowded news environment. Colleagues describe his style as calm, considered and quietly demanding on quality, with a strong editorial instinct shaped by years spent reading the markets his clients sell into.

A Cambridge graduate, Tom brings an analytical mindset to communications work that is too often run on instinct alone. He is a believer in the long arc of reputation, the value of being genuinely useful to journalists, and the idea that good B2B communications should sound like it was written by someone who understands the business, not just the brief.

He takes a particular interest in how professional services firms are adapting to shifts in buyer behaviour, AI-driven content discovery and the changing economics of trade media, and how communications teams can stay relevant as those forces reshape the market.
