Design that gets to the core of complex health tech.
An experienced product design team embedded at the core of health tech that actually matters. 10+ years designing complex, regulated app, web and SaaS products where getting it wrong has real consequences. Health and wellbeing apps, medical wearables, CQC regulated care platforms, AI powered symptom checkers, surgical tools. End to end, from discovery to shipped with care and craft.
• WHO WE ARE
Safety must be architected before it is designed.
Every complex system has a nucleus, the point everything else depends on. That's what Nucleus is built around.
Evidence over opinion
Every decision traces back to a user, a constraint, or a number.
Warm, never cold
Clinical grade clarity that still feels human to patients and staff.
Senior hands only
You work directly with us, never a junior, never a hand off.
Built to be audited
Documentation and rationale that hold up to regulators and review boards.
• What we do
Three ways we help
teams ship better care.
Product & UX design
End to end design for clinical tools, patient apps, and connected devices - from first concept to shipped, validated UI.
Research & validation
Contextual inquiry with clinicians and patients, usability studies, and the human factors evidence regulated products need.
Design systems
Accessible, auditable component libraries that keep large health platforms consistent as teams and products scale.

Insights synthesised
5 systemic failure patterns identified across 6 medication workflows. Evidence framework shaped engineering decisions across critical medication risk areas.
• How We Work
A method built for high stakes.
Immerse
We embed with your clinicians, users, and constraints until the real problem is unmistakable.
Frame
We turn messy complexity into a clear model, the riskiest assumptions, and a sharp design brief.
Design
Rapid, testable interfaces - refined against real workflows, not boardroom opinion.
Validate
Evidence from real users and the documentation regulated products need to move forward.

you're building.
We take on a handful of engagements at a time. A sentence or two about your product and timeline is enough to start the conversation.
