EU-funded research & innovation project

Buildchain — DKG Infrastructure & AI-Powered Knowledge Layer

Maistery contributed to Buildchain, an EU-funded initiative advancing digital infrastructure for the construction sector. Working within OriginTrail's Decentralized Knowledge Graph infrastructure, we designed and developed the Digital Building Logbook (DBL) module on DKG nodes, architected Decentralized RAG (DRAG) pipelines for Buildchain use cases, and delivered AI assistant capabilities on top of the DKG layer. The result is a tamper-proof, interoperable data layer that enables intelligent, verifiable data access across the construction supply chain.

ABOUT

Small team. Full ownership.

We stay lean by choice. AI is our structural capability, not a checkbox. We only take on what we can deliver at the highest level.

Maistery was founded on a simple belief: the most impactful software is built by people who understand both the technical depth and the intent behind every product.

We are intentionally small — not for lack of ambition, but because we refuse to take on projects we cannot deliver at the highest level. AI is our force multiplier, not a shortcut.

AI as architecture, not feature

We don't bolt AI onto existing systems. We design software where intelligence is structural — embedded in the data model, workflow, and user experience from day one.

Intentionally small

We stay lean by design. Every project we take on is one we can fully own and deliver. No handoffs to junior developers. No diluted attention. Full accountability from first commit to launch.

Zero-to-one is a discipline

Getting a product from idea to first users requires a different mindset than scaling. We specialise in the hardest part — the beginning — where clarity and speed matter most.

Quality from the first commit

We don't prototype to throw away. Every line of code is written as if it will be in production — because it usually is.

APPROACH

How we build.

We understand the problem deeply

Before any code, we invest in understanding the real problem — user behaviour, market gap, technical constraints. Good software starts with good questions.

We design with AI at the centre

We architect systems where AI is a first-class citizen. Data models, workflows, and interfaces are designed to leverage intelligent capabilities from the ground up.

We ship fast, iterate with intent

Speed matters, but not at the cost of coherence. We move fast by making smaller, better decisions — and iterate based on real feedback, not assumptions.

We own the outcome

Whether it's a product we built or a collaboration we contributed to, we take full ownership of the quality and impact of our work.

CONTACT

Let's build
something real.

Have a product idea, need a technical partner, or want to explore a collaboration? We're open to conversations that lead somewhere meaningful — and we only take on what we can deliver with mastery.
