AI Products Built by Experts to Serve Experts
Praxa
Knowledge, enacted.
We build AI products grounded in the domain expertise of real practitioners — not scraped from the web, but shaped by the people who have mastered their field. Expert-built AI, one domain at a time.

Praxa comes from the Greek praxis — knowledge lived out in action. It is the word Aristotle used to distinguish what domain experts do from what theorists merely know.
That distinction is the whole of our thesis. Most AI today is built on what has been written about a field. We build AI products on what is known by the practitioners who have spent careers mastering it.
The lab exists to close the gap between machine intelligence and mastered domain expertise — one domain, one expert, one product at a time.
What is expert-built AI?
Expert-built AI is not a prompt
on top of a general
model.
It is an intelligence grounded in the tacit knowledge of domain practitioners — knowledge that never appears in public datasets, never makes it into textbooks, and cannot be approximated from text alone. Praxa builds these products one domain, one expert, one product at a time.
No generalism. No compromise.

How we build expert-built AI.
A disciplined three-step process for encoding domain mastery into working AI intelligence.
Find the master
We begin with the practitioner, not the problem statement. Domain knowledge is identified at the source — in the hands and minds of those who have spent careers refining it.
What this looks like
We identify recognised practitioners in a specific domain — surgeons, structural engineers, senior litigators — whose judgment is trusted by peers, not just credentialed on paper.
The practitioner becomes a collaborator, not a data source. Their time is respected. Their methods are studied. Their edge cases are documented.
Encode the practice
We work closely with each expert to capture not just what they know, but how they reason, decide, and act under the specific pressures of their domain.
What this looks like
Structured sessions, case reviews, and protocol analysis distil tacit knowledge into explicit reasoning chains — the kind of thinking that never makes it into textbooks.
We focus on the decisions that distinguish a master from a competent practitioner. The edge cases. The weighted judgments. The knowing when not to act.
Make it operational
The result is a purpose-built intelligence grounded in real expertise — precise, auditable, and shaped by the people who do the work.
What this looks like
Each product is narrow by design. It solves one problem, in one domain, better than anything built from generalised data. That specificity is the feature.
Organisations deploy it with confidence because they can trace every output back to documented expert reasoning — not statistical approximation.
The distinction
Conventional AI
- Built on what has been written
- Generalised across all domains
- Extrapolated from text
- Knowledge at arm's length
- Theory approximating practice
Praxa
- Built on what is known by practitioners
- Mastered within a single domain
- Shaped by the people who do the work
- Expertise at the source
- Practice enacted as intelligence
Every application should reinforce our position as the thinking person's AI company — where knowledge meets action, and expertise becomes operational.

Common questions
about expert-built AI.
The difference between domain expertise and general AI is not a matter of degree. It is a difference in kind.
-
Expert-built AI combines domain-specific knowledge from industry practitioners with AI technology to create products that solve real problems with precision. Unlike generic AI, expert-built systems are shaped by professionals — surgeons, engineers, lawyers — who contribute tacit knowledge that no public dataset contains. Praxa works one domain, one expert, one product at a time.
-
Conventional AI is built on what has been written about a field — generalised across domains and extrapolated from public text. Expert-built AI is built on what is known by the people who practice in that field. The difference is between theory approximating practice, and practice enacted as intelligence. Expert-built AI products are narrower, more precise, and traceable back to documented domain expert reasoning.
-
Most AI projects fail because they are built on generalised data that lacks the tacit knowledge practitioners carry. Domain expertise covers edge cases, weighted judgments, and knowing when not to act — knowledge that never appears in textbooks or public datasets. Without a domain expert shaping the AI from the ground up, the resulting product approximates practice rather than enacting it.
-
Praxa works across domains where mastered expertise is the differentiator — including medicine, law, engineering, and finance. Each product is built in close collaboration with a recognised domain expert whose judgment is trusted by peers. Praxa takes a deliberately narrow approach: one domain, one expert, one product at a time.
-
It means every AI product is co-developed with a domain practitioner — not just validated by one — and the resulting product is designed to serve other professionals in that same field. The AI does not replace expert judgment; it operationalises it.
