We implement knowledge graphs.

We help you move to a data-centric model; we help you break free of rigidity, embrace knowledge and get you ready for AI.

Our founders are all experienced Principal Consultant level specialists in the Semantic Engineering and Knowledge Graph space. We have taken Knowledge Graph implementations from concept phase into production, across multiple industries, from finance to pharmaceutical, to engineering.

Our Philosophy

Meaning before mechanics.

Technology choices follow from well-defined conceptual models - never the other way around.

Governance is not optional.

Every ontology we build includes evolution pathways, ownership models, and quality frameworks.

Semantics is a product.

We design for continuous refinement. An ontology that can't evolve with the business is already technical debt.

What our clients say

Squirro

Most partnerships move slowly because you spend the first six months explaining how the technology works. With Semantic Partners, that phase did not exist. Their knowledge graph expertise meant they understood what Squirro does and why it matters before the first customer conversation. That changes the quality of the work they bring.

Dorian Selz

CEO

Squirro

Graphwise

As a Partner Sales Director of Graphwise, I have worked with Semantic Partners on multiple customer use cases. Semantic Partners are a Graphwise trusted consulting and implementation partner globally. They are agile, hands-on, knowledgeable, strategic, efficient, and effective - everything an AI & Knowledge Graph product vendor can expect from a professional services partner! Semantic Partners can be summarized as "Everything AI & Knowledge Graph"
