About Duncan Trevithick

Marketing operator who builds the system.

For more than eight years, I have worked across acquisition, content, SEO, analytics, lifecycle, and automation. I now focus on the connective work: building the tools and workflows that move demand into revenue.

Profile

From campaign work to operating systems.

I have worked inside B2B and B2C teams, with agencies, and as a product builder. That range helps me see the full motion: where demand begins, how data moves, which handoffs fail, and what should be built instead of managed by spreadsheet.

I am strongest where marketing operations, technical implementation, and commercial judgement meet. I work well with B2B teams that need one person to connect those layers and ship the result.
