Yellowhead Digital is Marketing Infrastructure Intelligence — we audit the systems most companies assume are working but rarely verify. We run forensic diagnostics across ten pillars: Attribution, Tech Stack, Conversion, Compliance, Brand Voice, Marketing, Advertising, Competitors, Product, and Discoverability (Web / SEO / AEO / GEO). You self-assess. Our system independently analyses reality. The gap is your roadmap. The free diagnostic takes minutes, not meetings. No credit card, no sales call. You get a scored report showing where you're solid and where you're bleeding money, leads, or trust. Every engagement runs on domain translation: we make the technical legible. By the end, you understand your own infrastructure well enough to decide without us. Three ways to work with us: Audit — See the gap, chart the course. Diagnostic → assessment → roadmap. Assist — We do the work. Website builds, campaigns, content. Every decision explained. Architect — We build the system. Nothing ships without a specification. System builds follow Spec-Driven Development (SDD). Every project starts with a written spec — plain language, approved before work begins, owned by the client. Most infrastructure fails not because it was built wrong, but because no one defined "right" before the build started. Led by Chris Enns — built attribution systems across programmatic, search, and social, run compliance-grade tracking where a misconfigured pixel was a regulatory problem, managed evidence databases where documentation rigour wasn't optional, and executed media at scale. He knows what the tools are supposed to do and what it looks like when they're not doing it. That experience spans regulated financial services, litigation support, and global media agencies. The forensic approach isn't a framework we adopted — it's how the work was learned, in environments where "close enough" had consequences. Based in British Columbia. Clients anywhere.
