From Strategy to Safe Deployment — Without the Guesswork
We help digital health companies design, test, and deliver AI systems through a behavioural science lens, with a focus on onboarding, adherence, retention, workflow quality, and patient experience.
A tailored approach to AI safety and real-world impact.
We work with organisations to design and deliver AI systems tailored to their specific goals, whether that is supporting complex tasks, improving user engagement, or strengthening confidence in safety and governance.
Our approach is deliberately flexible. Each system is shaped around your organisational context, user needs, and risk profile, aligning with relevant industry and regulatory expectations while remaining adaptable as requirements evolve.
AI systems that interact with people must be helpful without causing harm. We design and evaluate conversational and decision support AI through a behavioural and safety lens, ensuring systems are appropriate, evidence informed, and fit for real world use.
Evaluation is built into every stage of development. Using structured frameworks and tools such as PromptSafe, we simulate real world use through synthetic personas and behavioural criteria to identify risks early and support iterative improvement before deployment.
We also support teams to translate findings into clear, credible outputs for internal stakeholders, external partners, and research or dissemination where appropriate.

How we work
We support clients across three core service areas, helping teams design, test, and deploy AI systems in a structured and practical way.
AI strategy and development
We work with teams to define the right problems, design behaviourally informed systems, and support development from early feasibility through to deployment.
Our focus is on how AI systems interact with people, addressing behavioural risk, safety, usability, and performance from the outset.
PromptSafe evaluation platform
PromptSafe is our proprietary evaluation platform for testing AI systems that interact with people.
It simulates AI human interactions using synthetic personas and custom behavioural and safety criteria, helping teams identify risks, inconsistencies, and failure patterns early. PromptSafe can be embedded within development work or used independently to support ongoing evaluation.
Applied research and dissemination
We embed structured evaluation throughout the AI lifecycle to generate evidence that supports confident decision making.
We also help teams translate findings into clear, credible outputs for internal stakeholders, external partners, regulatory discussions, and where appropriate, publication.
Whether you are exploring a new AI concept or strengthening an existing system, we help you move forward with clarity and confidence.
