Digital Efficacy

Business transformation, AI & vibecoding

Business transformation, augmented by AI.

I help mid-to-large organizations turn ambitious AI and digital roadmaps into real operating-model change — across strategy, processes, data, tooling and the teams that have to run it. Hands-on. Vibecoded where it makes sense. Measured at every step.

From strategy to results

Three layers I work across.

Most organizations don't lack ideas — they lack a system that turns ideas into shipped, measured work. I plug into all three layers.

1

Strategy that holds up under load

Clarity on audience, value and operating model — for any function, not just marketing. Channels and processes that make sense. A plan your team can actually run.

2

Data and measurement that don't lie

Solid data foundations, end-to-end visibility and visual reporting so the whole org decides on evidence, not anecdote.

3

Team effectiveness, augmented by AI

Practical coaching, vibecoded internal tools, and AI workflows that raise the bar on execution, quality and speed across functions.

Why now

The gap isn't temporary. It's structural.

A 2026 study by the National Bank of Belgium, KU Leuven and Utrecht University analyzed 267,000 Belgian companies over two decades. After every IT investment, big firms gain market share; SMBs lose it. AI will widen that gap for the next decade. Transformation is no longer optional — it's the difference between staying competitive and being squeezed out.

What's new

AI, vibecoding & business transformation.

I'm spending most of my time today building AI-augmented operations — automating the boring 40%, shipping custom internal tools in days instead of quarters, and helping leadership teams turn AI from a buzzword into a P&L line.
