Clinical judgement.
A clearer view of AI.

Specialist clinical feedback for medical AI teams. From preference rankings for RLHF to reference answers for SFT, we help you identify errors, improve training examples and understand clinical risk.

NEUROSURGERYORTHOPAEDICS & TRAUMASHARED SPINE EXPERTISE

WHAT WE DO

Expert insight.
Usable feedback.

Clinical review and expert-authored data for AI developers, evaluation teams and specialist data partners. Each engagement has a named reviewer, agreed criteria and defined outputs.

01

Expert-in-the-loop RLHF

Clinical feedback to support reinforcement learning from human feedback (RLHF): compare model responses, rank preferences, flag factual and safety issues, and explain each judgement against an agreed rubric.

DELIVERY: PREFERENCE RANKINGS + CLINICAL RATIONALES
02

SFT reference answers & rubrics

Specialist-authored reference answers, corrections and fictional clinical scenarios for supervised fine-tuning (SFT) datasets. Agree the clinical scope and acceptance criteria before each batch.

DELIVERY: REFERENCE RESPONSES + REVIEW CRITERIA
03

Clinical content review

Check generated summaries and educational content for factual errors, important omissions and unsupported conclusions. Provide actionable corrections.

DELIVERY: ANNOTATIONS + CORRECTIONS
04

Surgical computer vision annotation

Discuss image or video annotation with a relevant specialist, including anatomy, instruments or procedural phases. We assess the material, label definitions, platform requirements and a calibration sample before confirming delivery.

START WITH: FEASIBILITY + ANNOTATION SCOPE

A CLEAR REVIEW PROCESS

From a defined question
to explained findings.

Agree the scope first. Make the criteria explicit. Keep the reasoning behind every finding visible.

  1. 01

    Scope

    Define the use case, specialty, language and output format. Confirm the appropriate reviewer.

  2. 02

    Calibrate

    Review a small sample together and agree how the scoring criteria should be applied.

  3. 03

    Evaluate

    Record scores, supporting explanations and proposed corrections. Resolve or flag uncertainty.

  4. 04

    Deliver

    Return structured findings, recurring error patterns and a discussion of the results and limits.

SPECIALTY MATCHING MATTERS

A second review is included only when it is agreed and an appropriately qualified reviewer is available. Each report describes the review actually performed.

THE PEOPLE BEHIND THE REVIEW

Clinical reviewers.

Two distinct specialties. Every assignment is matched to the relevant expertise and current clinical practice of the reviewer.

WHERE OUR EXPERTISE MEETS

Spine surgery brings two perspectives together. Where both doctors' expertise applies, independent reviews can be compared and differences documented.

DATA SECURITY & COMPLIANCE

Define the controls.
Then begin the review.

Data access and handling requirements belong in the pilot scope. Agree the environment and contractual requirements before sharing review material.

01

Client-controlled access

Request a workflow in your virtual desktop infrastructure (VDI) or an approved annotation environment. Platform suitability, named-user access and permitted exports are confirmed during scoping.

02

Retention & local handling

Set local-download restrictions, retention periods and deletion requirements in the project agreement. A no-local-copy workflow can be assessed against the client environment before access is granted.

03

GDPR & project agreements

Where personal data is involved, confirm the applicable data-processing agreement, processing locations and any subprocessors with your team before access. Security requirements are assessed for the actual project and deployment.

Start the conversation with a description or synthetic example. Please do not send identifiable patient data by email.

A PAID PILOT WITH A DEFINED SCOPE

One use case.
Clear deliverables.

Start with a small, paid evaluation batch in an agreed specialty. Confirm the reviewer, method, data environment, acceptance criteria, timeline and fixed fee before work begins.

Request a Paid Pilot

Agree your pilot deliverables

  • A named specialist and an agreed rubric
  • Case-level scores, rankings or reference responses
  • Written reasoning, corrections and open questions
  • A concise findings report and review discussion

Findings apply to the reviewed material and agreed scope. This review does not establish whole-product clinical validation or regulatory approval.

REQUEST A PAID PILOT

Bring us a use case.
We will scope the review.

Tell us the clinical specialty, workflow, language, sample size and target timeline. Include your preferred review platform or VDI requirements. Please keep identifiable patient data out of your enquiry.
