I don't just build products.
I question why they exist — and who they serve.

MAAR. is Bert Verstappen — a T-shaped digital creative turned AI-native product maker. Two decades of challenging the status quo with work that serves people, not just profit. Now building with AI to question faster, validate smarter, and ship products that actually matter.

What I actually do.

Not a studio. Not an agency. One person with twenty years of context and an AI-native toolkit.

From vague ambitions to concrete product visions. I help teams find clarity through structured ideation, opportunity mapping, and strategic framing -- always questioning assumptions before committing to solutions.

DiscoveryWorkshopsRoadmapping

Rapid prototyping powered by AI. I build functional prototypes and MVPs at startup speed, using AI-native tools to validate ideas before they become expensive mistakes.

Vibe CodingAI AgentsRapid MVP

Small, elegant products built end-to-end. From concept to deployed infrastructure -- secure, tested, scalable solutions that actually ship. Not enterprise-scale, but production-ready apps you can trust in the real world.

Full-StackDevOpsDeployment

Agile product ownership with a creative edge. Sprint planning, backlog management, stakeholder alignment, and QA -- but always with one eye on the bigger picture.

Test before you invest. Customer development interviews, prototype testing, market validation, and lean experimentation to separate signal from noise.

Two decades of crafting digital experiences, from interactive campaigns for global brands to startup interfaces. Design that serves the product, not the other way around.
