Experience in context
Commercial judgement built across channels.
Jack has worked in digital marketing for more than 15 years, from early social and content work through paid acquisition, ecommerce, affiliate partnerships and measurement. That breadth shapes the Spires Digital model: a channel should be judged by the commercial job it performs, not by the amount of credit its own dashboard claims.
He has overseen more than £10m in cumulative advertising spend and more than 150 campaigns. Those figures describe the scale of experience behind the work; they are not presented as an average result or a guarantee for an individual client.
Jack leads the initial diagnosis, commercial model, channel strategy and major optimisation decisions. Specialist support is added where the agreed scope requires it, while the client retains direct access to the person accountable for the recommendation.
