About

About digital efficacy.

Digital Efficacy is an independent consultancy turning AI capability into real operating-model change for mid-to-large organizations across the Benelux and the wider EU. Run by Mathieu Van de Velde from Lochristi, Belgium — fifteen years of operator-grade depth, end-to-end from boardroom diagnosis to shipped tooling. No juniors in disguise. No slideware that doesn't ship.
At the Digital Marketing Awards

From SEM to business transformation.

My path started in 2010 at bSeen, a Search Engine Marketing agency. In 2012 I moved to The Reference (now part of EPAM) to work with larger, international clients — Fortune 500 brands, high-growth e-commerce, B2B and B2C, branding through lead generation, marketing automation and analytics. Fifteen years of operator-grade depth, not theory.

Today that depth is the foundation, not the headline. My focus has shifted into AI enablement, vibecoded internal tooling and operating-model change. The reason marketing teams used to hire me — pragmatic delivery, sharp diagnosis, tools that actually ship — is precisely what makes the broader transformation work land for leadership teams now.

01

Transformation Partner

I partner with leadership teams when AI strategy needs to become operating-model reality. Process redesign, governance, capability mapping and a 90-day execution plan that survives contact with finance. Not slides — the work.

02

Strategist & Builder

Strategy that ships. I write the brief, and I'll write the prototype too if that's what gets the team unblocked. Comfortable across the stack — Claude, Microsoft 365, GitHub, HubSpot, Supabase, Next.js, Vercel — and the LLM tooling layered on top.

03

Trainer & Coach

Hands-on workshops where teams ship a working prototype by lunch and walk out with a personal AI toolkit they actually use the next day. The half of AI adoption that lives in change management — not the half that lives in a 60-slide policy doc.
